SIGNIFICANCE AND USE
5.1 This practice is for use by designers and specifiers, regulatory agencies, owners, contractors, and inspection organizations who are involved in rehabilitation of pressurized piping systems.
SCOPE
1.1 This standard is intended to establish the minimum criteria necessary for use of a mechanically mixed, blended, epoxy barrier coating (AWWA Class I) that is applied to the interior of 1/2 in. (12.7 mm) to 36 in. (914.4 mm) metallic pipe or tube used in pressurized piping systems for corrosion protection and to improve flow rates. There is no restriction as to the developed length of the piping system other than the method of application (“blow through”, spin cast or hand sprayed) and the characteristics of the epoxy coating being applied but the manufacturer’s engineer shall be consulted for any limitations associated with this product, process and its application for the end user.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Breaks or holidays in a coating applied over steel exposes the substrate to a potential corrosion cell. When the steel is subjected to cathodic protection by the polarization of the steel via sacrificial anodes or impressed current, the exposed steel at the holiday becomes the cathode in the corrosion cell. When the electrolyte is neutral or slightly alkaline, hydroxyl ions form from the reduction of oxygen and, when paired with a suitable cation from the electrolyte, form an alkaline solution. Depending on the strength of this alkaline solution and the concentration of the alkaline compound, this alkalinity may disrupt the adhesion between the coating and the steel, disbonding the coating from the steel.  
4.2 Current density of the cathodic cell also can affect the degree of cathodic disbondment. The greater the current density generated by the concentration of electrons at the anode, the greater the number of hydroxyl ions formed, thus increasing the alkalinity available for disrupting the adhesion between the coating and the steel substrate. Likewise, the concentration of oxygen in the electrolyte will affect the concentration of hydroxyl ions formed at the cathode.  
4.3 For these reasons it is often useful to measure pH, oxygen, and current density when conducting a cathodic disbondment test.
SCOPE
1.1 These test methods apply to procedures for determining the degree of disbondment of a coating from a steel substrate when placed in contact with an electrolyte and a potential is applied to the steel. Specimens may include coated steel pipe or coated flat or curved steel plate. The coating applied to the steel substrate shall be non-metallic and shall not show flow characteristics at the test temperature.  
1.2 These test methods apply to specimens that are immersed in an electrolyte bath or specimens with an attached electrolyte cell at ambient room temperature, 21 °C to 25 °C (70 °F to 77 °F), conditions. If higher temperatures are required, use Test Method G42.  
1.3 These test methods apply to methods of polarization including sacrificial anodes or impressed current applied to the steel by a rectifier.  
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
5.1 The purpose of this practice is to outline a procedure for using GWT to locate areas in metal pipes in which wall loss has occurred due to corrosion or erosion.  
5.2 GWT does not provide a direct measurement of wall thickness, but is sensitive to a combination of the CSC and circumferential extent and axial extent of any metal loss. Based on this information, a classification of the severity can be assigned.  
5.3 The GWT method provides a screening tool to quickly identify any discontinuity along the pipe. Where a possible defect is found, follow-up inspection of suspected areas with ultrasonic testing or other NDT methods is normally required to obtain detailed thickness information, nature, and extent of damage.  
5.4 GWT also provides some information on the axial length of a discontinuity, provided that the axial length is longer than roughly a quarter of the wavelength of the excitation signal.  
5.5 The identification and severity assessment of any possible defects is qualitative only. An interpretation process to differentiate between relevant and non-relevant signals is necessary.  
5.6 This practice only covers the application specified in the scope. The GWT method has the capability and can be used for applications where the pipe is insulated, buried, in road crossings, and where access is limited.  
5.7 GWT shall be performed by qualified and certified personnel, as specified in the contract or purchase order. Qualifications shall include training specific to the use of the equipment employed, interpretation of the test results and guided wave technology.  
5.8 A documented program that includes training, examination and experience for the GWT personnel certification shall be maintained by the supplying party.
SCOPE
1.1 This practice provides a procedure for the use of guided wave testing (GWT), also previously known as long range ultrasonic testing (LRUT) or guided wave ultrasonic testing (GWUT).  
1.2 GWT utilizes ultrasonic guided waves, sent in the axial direction of the pipe, to non-destructively test pipes for defects or other features by detecting changes in the cross-section or stiffness of the pipe, or both.  
1.3 GWT is a screening tool. The method does not provide a direct measurement of wall thickness or the exact dimensions of defects/defected area; an estimate of the defect severity however can be provided.  
1.4 This practice is intended for use with tubular carbon steel or low-alloy steel products having Nominal Pipe size (NPS) 2 to 48 corresponding to 60.3 mm to 1219.2 mm (2.375 in. to 48 in.) outer diameter, and wall thickness between 3.81 mm and 25.4 mm (0.15 in. and 1 in.).  
1.5 This practice covers GWT using piezoelectric transduction technology.  
1.6 This practice only applies to GWT of basic pipe configuration. This includes pipes that are straight, constructed of a single pipe size and schedules, fully accessible at the test location, jointed by girth welds, supported by simple contact supports and free of internal, or external coatings, or both; the pipe may be insulated or painted.  
1.7 This practice provides a general procedure for performing the examination and identifying various aspects of particular importance to ensure valid results, but actual interpretation of the data is excluded.  
1.8 This practice does not establish an acceptance criterion. Specific acceptance criteria shall be specified in the contractual agreement by the responsible system user or engineering entity.  
1.9 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

SIGNIFICANCE AND USE
5.1 Method A—Low voltage holiday detection is used to locate holidays and pinholes in thin-film coatings (up to 0.508 mm (20 mils) using a sponge wetted with tap water (and a wetting agent for coatings thicker than 10 mils). The water carries the current from the electrode through the holiday to the conductive substrate. The detector is grounded to the coated substrate. When the detector senses this flow of current it alarms.  
5.2 Method B—High voltage holiday detection is used to locate holidays and pinholes in thick-film coatings (greater than 20 mils), but can be used on coatings as low as 10 mils thick. A test voltage is selected and set. A charged Electrode is placed in contact with the coating, and the Detector is grounded to the coated substrate. When Electrical Breakdown occurs, electric current flows between the Detector’s electrode and the conductive substrate and emits an audible alarm.  
5.3 This standard does not apply to holiday detection of tape wraps used to protect pipe or coatings containing conductive raw materials such as conductive pigments and extenders.  
5.4 The thickness of a coating applied to ductile iron pipe, fittings, or other iron castings may vary substantially due to the inherent roughness of the substrate. For these applications, consult the coating manufacturer for their recommended test voltage setting when using Method B. The coating manufacturer’s recommended test voltage setting may be subject to approval by the owner.
Note 1: Use of voltage settings lower than those listed in this standard may increase the likelihood of non-detection.
SCOPE
1.1 These test methods cover the apparatus and procedures for detecting pinholes and holidays in coatings used to protect pipelines.  
1.2 Method A is designed to detect pinholes and holidays in thin-film coatings from 0.025 mm to 0.254 mm (1 mils to 10 mils) in thickness using ordinary tap water and an applied voltage of less than 100 V d-c. It is effective on films up to 0.508 mm (20 mils) thickness if a wetting agent is used with the water.  
1.3 Method B is designed to detect pinholes and holidays in thick-film coatings >0.508 mm (20 mils) This method can be used on any thickness of pipeline coating and utilizes applied voltages between 3.4 and 35 kV d-c.  
1.4 The values stated in SI units to three significant decimals are to be regarded as the standard. The values given in parentheses are for information only.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 When permitted by a specification or the order, this test method may be used for detecting leaks in tubing in lieu of the air underwater pressure test.
SCOPE
1.1 This test method provides procedures for the leak testing of tubing using pneumatic pressure. This test method involves measuring the change in pressure inside the tubing over time. There are three procedures that may be used, all of which are intended to be equivalent. It is a qualitative not a quantitative test method. Any of the three procedures are intended to be capable of leak detection and, as such, are intended to be equivalent for that purpose.  
1.2 The procedures will produce consistent results upon which acceptance standards can be based. This test may be performed in accordance with the Pressure Differential (Procedure A), the Pressure Decay (Procedure B), or the Vacuum Decay (Procedure C) method.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

SIGNIFICANCE AND USE
5.1 Elemental sulfur impacts the quality of pipeline natural gas and deposits on pipeline flanges, fittings and valves, thereby impacting their performance. Natural gas suppliers and distributers require a standardized test method for measuring elemental sulfur. Some government regulators are also interested in measuring elemental sulfur since it would provide a means for assessing the contribution of elemental sulfur in pipelines to the SOx emission inventory from burning of gaseous fuels. Use of this method in concert with sulfur gas laboratory test methods such as Test Methods D4084, D4468, D5504, and D6228 or on-line methods such as D7165 or D7166 can provide users with a comprehensive sulfur compound profile for natural gas or other gaseous fuels. Other applications may include elemental sulfur in particulate deposits such as diesel exhausts.
SCOPE
1.1 This test method is primarily for the determination of elemental sulfur in natural gas pipelines, but it may be applied to other gaseous fuel pipelines and applications provided the user has validated its suitability for use. The detection range for elemental sulfur, reported as sulfur, is 0.0018 mg/L to 30 mg/L. The results may also be reported in units of mg/kg or ppm.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

5.8 A documented program which includes training, examination, and experience for the GWT personnel certification shall be maintained by the supplying party.
SCOPE
1.1 This practice provides a guide for the use of waves generated using magnetostrictive transduction for guided wave testing (GWT) welded tubulars. Magnetostrictive materials transduce or convert time varying magnetic fields into mechanical energy. As a magnetostrictive material is magnetized, it strains. Conversely, if an external force produces a strain in a magnetostrictive material, the material’s magnetic state will change. This bi-directional coupling between the magnetic and mechanical states of a magnetostrictive material provides a transduction capability that can be used for both actuation and sensing devices.  
1.2 GWT utilizes ultrasonic guided waves in the 10 to approximately 250 kHz range, sent in the axial direction of the pipe, to non-destructively test pipes for discontinuities or other features by detecting changes in the cross-section or stiffness of the pipe, or both.  
1.3 GWT is a screening tool. The method does not provide a direct measurement of wall thickness or the exact dimensions of discontinuities. However, an estimate of the severity of the discontinuity can be obtained.  
1.4 This practice is intended for use with tubular carbon steel products having nominal pipe size (NPS) 2 to 48 corresponding to 60.3 to 1219.2 mm (2.375 to 48 in.) outer diameter, and wall thickness between 3.81 and 25.4 mm (0.15 and 1 in.).

This includes pipes that are straight, constructed of a single pipe size and schedules, fully accessible at the test location, jointed by girth welds, supported by simple contact supports and free of internal, or external coatings, or both; the pipe may be insulated or painted.  
1.6 This practice provides a general practice for performing the examination. The interpretation of the guided wave data obtained is complex and training is required to properly perform data interpretation.  
1.7 This practice does not establish an acceptance criterion. Specific acceptance criteria shall be specified in the contractual agreement by the cognizant engineer.

This document provides information on methods suitable for assessing the likelihood of leakage due to external corrosion of well casings and to evaluate the need for cathodic protection, as well as methods of providing cathodic protection to the external part of these wells in contact with the soil. It also defines requirements for monitoring of performance of CP systems.
Onshore and offshore wells are included in the scope. However, for offshore wells where protection is provided by anodes on the wellhead structure, it is recognized that it might not be practical to achieve full protection of well casings.
This document applies to any gas, oil or water well with metallic casing, whether cemented or not.
However, in special conditions (shallow casings: e.g. 50 m, and homogeneous soil), EN 12954 can be used to achieve the cathodic protection and assess its efficiency.
The general requirements of EN 12954 apply; this document details additional, specific, requirements for CP of well casings.
This document applies to production and injection wells. References later in this document to production also apply to injection.

As for any practice, modifications may be required for specific job conditions.
SCOPE
1.1 This practice covers requirements and test methods for the sectional cured-in-place lining (SCIPL) repair of a pipe line (4 in. through 60 in. (10.2 cm through 152 cm)) by the installation of a continuous resin-impregnated-textile tube into an existing host pipe by means of air or water inversion and inflation. The tube is pressed against the host pipe by air or water pressure and held in place until the thermoset resins have cured. When cured, the sectional liner shall extend over a predetermined length of the host pipe as a continuous, one piece, tight fitting, corrosion resistant, and verifiable non-leaking cured-in-place pipe.

SIGNIFICANCE AND USE
5.1 Test Method A—This test method is the most frequently used in leak testing components. Testing of components is correlated to a standard leak, and the actual leak rate is measured. Acceptance is based on the maximum system allowable leakage. For most production needs, acceptance is based on acceptance of parts leaking less than an established leakage rate, which will ensure safe performance over the projected life of the component. Care must be exercised to ensure that large systems are calibrated with the standard leak located at a representative place on the test volume. As the volume tends to be large (>1 m3) and there are often low conductance paths involved, a check of the response time as well as system sensitivity should be made.  
5.2 Test Method B—This test method is used for testing vacuum systems either as a step in the final test of a new system or as a maintenance practice on equipment used for manufacturing, environmental test, or conditioning parts. As with Test Method A, the response time and a system sensitivity check may be required for large volumes.  
5.3 Test Method C—This test method is to be used only when there is no convenient method of connecting the LD to the outlet of the high-vacuum pump. If a helium LD is used and the high-vacuum pump is an ion pump or cryopump, leak testing is best accomplished during the roughing cycle, as these pumps leave a relatively high percentage of helium in the high-vacuum chamber. This will limit the maximum sensitivity that can be obtained.
SCOPE
1.1 This practice covers procedures for testing the sources of gas leaking at the rate of 1 × 10 −8 Pa m3/s (1 × 10−9  standard-cm3/s at 0 °C) or greater. These test methods may be conducted on any object that can be evacuated and to the other side of which helium or other tracer gas may be applied. The object must be structurally capable of being evacuated to pressures of 0.1 Pa (approximately 10−3 torr).  
1.2 Three test methods are described;  
1.2.1 Test Method A—For the object under test capable of being evacuated, but having no inherent pumping capability.  
1.2.2 Test Method B—For the object under test with integral pumping capability.  
1.2.3 Test Method C—For the object under test as in Test Method B, in which the vacuum pumps of the object under test replace those normally used in the leak detector (LD).  
1.3 Units—The values stated in either SI or std-cc/sec units are to be regarded separately as standard. The values stated in each system may not be exact equivalents: therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document provides information on methods suitable for assessing the likelihood of leakage due to external corrosion of well casings and to evaluate the need for cathodic protection, as well as methods of providing cathodic protection to the external part of these wells in contact with the soil. It also defines requirements for monitoring of performance of CP systems.
Onshore and offshore wells are included in the scope. However, for offshore wells where protection is provided by anodes on the wellhead structure, it is recognized that it might not be practical to achieve full protection of well casings.
This document applies to any gas, oil or water well with metallic casing, whether cemented or not.
However, in special conditions (shallow casings: e.g. 50 m, and homogeneous soil), EN 12954 can be used to achieve the cathodic protection and assess its efficiency.
The general requirements of EN 12954 apply; this document details additional, specific, requirements for CP of well casings.
This document applies to production and injection wells. References later in this document to production also apply to injection.

SIGNIFICANCE AND USE
5.1 The corrosion observed on steel and other materials under thermal insulation is of great concern for many industries including chemical processing, petroleum refining and electric power generation. In most cases, insulation is utilized on piping and vessels to maintain the temperatures of the operating systems for process stabilization and energy conservation. However, these situations can also provide the prerequisites for the occurrence of general or localized corrosion, or both, and in stainless steels, stress corrosion cracking. For example, combined with elevated temperatures, CUI can sometimes result in aqueous corrosion rates for steel that are greater than those found in conventional immersion tests conducted in either open or closed systems (see Fig. 1).3 This figure shows actual CUI data determined in the field compared with the corrosion data from fully immersed corrosion coupons tests.
FIG. 1 Comparison of Actual Plant CUI Corrosion Rates Measurements (Open Data Points Shown is for Plant CUI) with Laboratory Corrosion Data Obtained in Open and Closed Systems  
Note 1: The actual CUI corrosion rates can be in excess of the those obtain in conventional laboratory immersion exposures.  
5.2 This guide provides a technical basis for laboratory simulation of many of the manifestations of CUI. This is an area where there has been a need for better simulation techniques, but until recently, has eluded many investigators. Much of the available experimental data is based on field and in-plant measurements of remaining wall thickness. Laboratory studies have generally been limited to simple immersion tests for the corrosivity of leachants from thermal insulation on corrosion coupons using techniques similar to those given in Guide G31. The field and inplant tests give an indication of corrosion after the fact and can not be easily utilized for experimental purposes. The use of coupons in laboratory immersion tests can give a general indication of corrosio...
SCOPE
1.1 This guide covers the simulation of corrosion under insulation (CUI), including both general and localized attack, on insulated specimens cut from pipe sections exposed to a corrosive environment usually at elevated temperature. It describes a CUI exposure apparatus (hereinafter referred to as a CUI-Cell), preparation of specimens, simulation procedures for isothermal or cyclic temperature, or both, and wet/dry conditions, which are parameters that need to be monitored during the simulation and the classification of simulation type.  
1.2 The application of this guide is broad and can incorporate a range of materials, environments and conditions that are beyond the scope of a single test method. The apparatus and procedures contained herein are principally directed at establishing acceptable procedures for CUI simulation for the purposes of evaluating the corrosivity of CUI environments on carbon and low alloy pipe steels, and may possibly be applicable to other materials as well. However, the same or similar procedures can also be utilized for the evaluation of (1) CUI on other metals or alloys, (2) anti-corrosive treatments on metal surfaces, and (3) the potential contribution of thermal insulation and its constituents on CUI. The only requirements are that they can be machined, formed or incorporated into the CUI-Cell pipe configuration as described herein.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
5.1 This test method is intended to standardize the cyclic movement of a through-penetration firestop system prior to a fire resistance test. If the amplitude of movement in a design application can be predicted, then the numerical values of allowable movement can be used as one data point in helping to establish suitability of the through-penetration firestop system for the given application.
Note 4: The fire resistance rating of a through-penetration firestop system is established in accordance with a relevant fire test, as acceptable to the Authority Having Jurisdiction. Examples of such tests include Test Method E814, CAN/ULC-S115, UL 1479, and ISO 10295-1.  
5.2 This test method will assist users, producers, building officials, code authorities, and others in understanding relative movement capabilities of representative test specimens of through-penetration firestop systems under standardized test conditions.  
5.3 This test method is not intended to predict the absolute movement capabilities of all likely permutations of through-penetration firestop systems under all likely types of real-life movement.  
5.4 This test method does not provide information on:  
5.4.1 Durability of the through-penetration firestop system under actual service conditions, including the effects of cycled temperature on the through-penetration firestop system;  
5.4.2 Rotational shear capabilities of the test specimen;  
5.4.3 Any other attributes of the test specimen, such as wear resistance, chemical resistance, air infiltration, water-tightness, and so forth; and  
5.4.4 Compatibility of through-penetration firestop system components and the penetrating items.  
5.5 This test method is only to be used as one element in the selection of a through-penetration firestop system for a particular application.  
5.6 This is not a fire test standard. To determine the effect of cyclic movement on the fire resistance rating of a though-penetration firestop system, conduct a fire ...
SCOPE
1.1 This test method covers testing procedures for through-penetration firestop systems. This test method is intended for the following uses:
Note 1: Refer to Test Method E814 for definition of “through-penetration firestop system.”  
1.1.1 To determine relative movement capability in two separate and distinct planes of movement for different types of through-penetration firestop systems,  
1.1.2 To standardize a comparison of movement capability by establishing standardized test conditions, in order to allow the type of through-penetration firestop system’s movement capabilities to be examined,  
1.1.3 To provide the user with information on amplitudes of relative movement between the penetrating items and the substrate (concrete-based or gypsum-based).
Note 2: Amplitude is the measure of change over a single cycle.  
1.2 This test method is intended to be used only as part of a specification or acceptance criteria due to the limited movements tested, and limited number of variables examined.  
1.3 This test method uses standardized configurations for the test specimen. Test results will not be representative of all possible through-penetration firestop systems.

This document describes the general principles for the implementation and management of a system of cathodic protection against corrosive attacks on structures which are buried or in contact with soils, surface fresh waters or underground waters, with and without the interference of external electrical sources. It specifies the protection criteria to be achieved to demonstrate the cathodic protection effectiveness.
For structures that cannot be electrically isolated from neighbouring influencing structures, it may be impossible to use the criteria defined in the present document. In this case, EN 14505 will be applied (see 9.4 "Electrical continuity/discontinuity").
To assist in forming a decision whether or not to apply cathodic protection the corrosion likelihood can be evaluated using Annex A. Annex A summarizes the requirements of EN 12501-1 [2] and EN 12501-2 [3].
Cathodic protection of structures immersed in seawater is covered by EN 12473 and a series of standards more specific for various applications.
Cathodic protection for reinforced concrete structures is covered by EN ISO 12696.
This document is applicable in conjunction with:
-   EN ISO 15589-1 for application for buried or immersed cathodically pipelines,
-   EN 50162 to manage d.c. stray currents,
-   EN ISO 18086 to manage corrosion due to a.c. interference from high voltage power sources and a.c. traction systems,
-   EN 13509 for cathodic protection measurement techniques
-   EN 50443 to manage protection for touch and step voltage.

SIGNIFICANCE AND USE
4.1 This guide provides basic information on the application of cathodic protection to polyethylene encased ductile iron pipe for engineers, owners, water companies, corrosion consultants, ductile iron (DI) pipe manufacturers and others who have an interest in providing underground corrosion protection to ductile iron pipe.  
4.2 There are many publications, standards, recommended practices, and specifications for the application of coatings and cathodic protection to steel pipe. However, the metallurgy, chemistry, physical properties, surface composition and texture, coating requirements and electrical continuity of standard production ductile iron pipe are significantly different than those of steel pipe, and coating and cathodic protection specifications written specifically for steel pipe may not be directly applicable to ductile iron pipe. The latest revision of a commonly accepted cathodic protection specification (NACE SP0169) states the following in the forward: “This standard does not include corrosion control methods based on injection of chemicals into the environment, on the use of electrically conductive coatings, or on the use of non-adhered polyethylene encasement (refer to NACE Publication 10A292).” It is the purpose of this guide to summarize publications, case histories, and studies which are available regarding cathodic protection installations of polyethylene encased ductile iron pipe to give the reader guidance on this unique method of protection.  
4.3 This guide may be utilized with galvanic or impressed current cathodic protection.  
4.4 This guide is written specifically for ductile iron pipe and does not apply to any other type of piping material. It may also be used for ductile iron fittings, valves, and appurtenances specific to ductile iron piping systems.  
4.5 This guide references requirements for vendor provided information which should be requested and reviewed by the user.
SCOPE
1.1 This guide will discuss standard practices which have been successfully utilized in the field for over 35 years to provide external corrosion protection of polyethylene encased ductile iron pipe supplemented with cathodic protection (CP). This guide may also be used for ductile iron fittings, valves, and other appurtenances specific to ductile iron pipe systems. Case histories and publications reporting on the use of cathodic protection to supplement polyethylene encasement are included as an Appendix in this guide.  
1.2 Other external corrosion control methods which have been used for ductile iron pipe include, but are not limited to: cathodic protection, metallic zinc coatings, bonded dielectric coatings, dielectric coatings with cathodic protection, and trench improvement. Detailed information on these methods of protection are available from other sources and are beyond the scope of this guide.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
3.1 Holidays in pipeline coatings may be repaired by circumferential wrapping with a suitable pipe wrap tape. However, this technique is not always practicable and patching may be required. The effectiveness of a patch material depends upon its adhesion to the original pipeline coating to effect sealing.  
3.2 The results of this accelerated test have been found to yield comparative data useful for the selection of patching materials. The user is cautioned against the use of this method for absolute material properties characterization.  
3.3 This procedure provides an accelerated method by exposing the patch to a severe radius of curvature on small-diameter pipe. The specimen is also exposed to a stress voltage in the presence of a highly conductive electrolyte.
SCOPE
1.1 This test method provides an accelerated means of determining the relative sealing abilities of pipeline patching materials that are used to seal holidays in pipeline coatings on steel pipe. This test method is intended for utilization of specimens of pipeline coatings on small-diameter pipe, for representing coatings used for buried or submerged service, and where the purpose of the coating is to provide an electrical barrier between the steel pipe and its environment.  
1.2 This test method is not intended for evaluating patch materials that are overlapped upon themselves.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

This document, in conjunction with ISO 11296-1, specifies requirements and test methods for pipes which are formed on site by spirally winding and jointing a pre-manufactured profiled plastics strip, or a profiled plastics strip and integral locking joiner strip, and used for the renovation of underground non-pressure drainage and sewerage networks.
It applies to spirally-wound pipes of fixed or variable diameter made of profiled plastics strips, with or without steel stiffening elements, and installed by one of two methods.
The first method employs a dedicated winding machine in front of the open end of an existing pipeline, e.g. in a manhole. The pipes thus formed are simultaneously inserted into the existing pipeline by the winding forces, and by certain techniques can also be expanded in diameter after or during insertion.
The second method employs a dedicated winding machine which forms the pipe as it traverses the existing pipeline from one manhole to the next.
It applies to profiled plastics strips of unplasticized poly(vinyl chloride) (PVC U) with integral locking mechanism, or of high density polyethylene (HDPE) with integrally welded joints.

ABSTRACT
This specification covers fabrication techniques for cellular glass block into billets to fabricate pipe and tubing insulation. The optimization of the thermal performance of installed cellular glass insulation systems is discussed. This is best achieved by limiting the number of joints, in particular through joints. Cellular glass pipe and tubing insulation shall be fabricated from the minimum number of insulation blocks. Sectional pipe insulation shall contain not more than four through joints per full section of insulation, excluding the half section mating plane. Fabrication adhesive shall be hot asphalt, Type II operating at some temperature. For operating temperatures above ambient, fabrication adhesive shall include but not be limited to Type II hot asphalt, elastomeric asphalt, or gypsum-based cement of the type and grade specified. Fabricating adhesive shall be applied such that there is 100% coverage of adhesive on the mating surfaces. Billet and miter construction shall conform to the following: insulation blocks or sections shall be hand rubbed if necessary to fit prior to bonding and bond joints shall be made with a full depth of approved adhesive. Bond joints can be classified as “non-through” joints which start at the outside circumference and run continuously in a straight line to the opposite side terminating at the outside circumference. “Through” joints start at the outside circumference and runs continuously in a straight line to the opposite side and terminates at the inside circumference. All segmented pipe insulation shall be edge trimmed at the fabrication site. Either a grinder or a saw shall be used to edge trim segmented pipe insulation. If segmented pipe insulation is edge trimmed using a saw blade, edges shall be rubbed to remove uneven patterns caused by flexing blade where needed. Fittings for all sizes shall be either factory ground or factory mitered.
SCOPE

ABSTRACT
This test method describes a procedure for qualifying the performance of joint restraint products for use on PVC pressure pipe systems by evaluating the effect of the joint restraint product on the performance characteristics of PVC pipe during cyclic pressure tests and static pressure tests. This test method is useful for establishing any effects that a joint restraint product has on the performance of PVC pressure pipe. This test method is designed so that success in all three parts of the test provides reasonable assurance that a joint restraint product may be used on PVC pipe at the full pressure rating and capacity of the pipe. Pipe specimen length, minimum burst pressure test, sustained pressure test, and cyclic surge pressure test shall be performed to conform with the specified requirements.
SIGNIFICANCE AND USE
4.1 This test method is useful for establishing any effects that a joint restraint product has on the performance of PVC pressure pipe. This test method is designed so that success in all three parts of the test provides reasonable assurance that a joint restraint product may be used on PVC pipe at the full pressure rating and capacity of the pipe.  
4.2 Restrained joint test specimens shall be subjected to internal pressures that are equal to the minimum burst pressure requirements for the pipe alone. The minimum burst pressure requirements for some common dimension ratios are shown in Table 1. The minimum burst pressures for other dimension ratios of pipe produced from 12454 PVC Compound (that is, pipe conforming to Specification D1785) may be determined based on a hoop stress of 6400 psi (44.13 MPa).  (A) The pressures listed approximate a hoop stress of 6400 psi (44.13 MPa). Some minor adjustments have been made to keep the test pressures uniform in order to simplify testing.  
4.3 Testing of restrained joint test specimens for 1000 h at the sustained pressure requirements indicates any tendency of the restraint to fail in the long term. The minimum sustained pressure requirements for some common dimension ratios are shown in Table 2. The minimum sustained pressure for other dimension ratios of pipe produced from 12454 PVC Compound (for example, pipe conforming to Specification D1785) may be determined based on a hoop stress of 4200 psi (28.96 MPa).  (A) The pressures listed approximate a hoop stress of 4200 psi (28.96 MPa). Some minor adjustments have been made to keep the test pressures uniform in order to simplify testing.  
4.4 A cyclic surge pressure test of restrained joint test specimens determines the effect of the joint restraint product on the cyclic fatigue life of PVC pipe. This test method provides a means for quickly identifying any reduction in performance that might result from the combination of the joint restraint product and the pipe. The...

1.1 This test method describes a procedure for qualifying the performance of joint restraint products for use on PVC pressure pipe systems by evaluating the effect of the joint restraint product on the performance characteristics of PVC pipe during cyclic pressure tests and static pressure tests. The PVC pipe property values referenced in this test method are for the 12454 compound as described in Specification D1784 and a 4,000 HDB shall be obtained by categorizing the LTHS in accordance with Table 1 in Test Method D2837. That includes, but is not limited to, pipe produced in accordance with the following standards: Specifications D1785 and D2241, and AWWA C900.  
1.2 This test method determines the short-term performance of a joint restraint product on PVC pipe, which involves the testing of restrained joint test sections to the minimum burst pressure requirements of the pipe to determine quick burst performance.  
1.3 This test method determines the long-term effect of a joint restraint product on PVC pipe, which involves the testing of restrained joint test sections to the sustained pressure requirements of...
