SIGNIFICANCE AND USE
5.1 This test method is intended to determine if a joint that is subjected to a mechanically induced cut will resist tear propagation during normal joint movement.
Note 1: A sealant with a high resistance to tear propagation may perform better than a sealant with a low resistance to tear propagation.
SCOPE
1.1 This test method evaluates the impact of an induced tear on a sealant specimen that is dimensioned, cured according to the guidelines in Test Method C719 and then subjected to a constant strain. It is effective in differentiating between sealants that are used in dynamic joints subject to abrasion, punctures, tears, or combination thereof.
1.2 Since this test method is for the evaluation of tear propagation, an adhesive failure to the substrates provides no usable data regarding tear propagation. This would be considered a failed test and that data would be discarded, or at least separated from the other data from specimens that did not experience an adhesive failure.
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 standard is similar in concept to European Technical Approval Guidelines (ETAG) 002, Part 1, Section 5.1.4.6.4—Resistance To Tearing.
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
5.1 If required by the authority having jurisdiction, pressurized gaseous testing media leak testing is conducted after installation to discover and correct or repair leaks or faults in a newly constructed or modified PA12 pressure piping system before placing the system in service. Leakage or faults most commonly occur at connections, joints, and mechanical seals where sealing under pressure is required.
5.2 Safety is of paramount importance when conducting pressurized gaseous testing media leak tests because testing results include no leaks, leaks, sudden violent rupture, or catastrophic failure.
5.3 Systems that contain lower pressure rated or non-pressure rated components that cannot be isolated or removed from exposure to test pressure, or where temporary caps or closures are not practical, are not suitable for testing in accordance with this practice.
5.4 Leakage Allowance—Leakage is not allowed for butt and electrofusion joints, and restrained gas-tight mechanical joints. See 7.6. Contact the joint, connection or component manufacturer for leakage correction information if leakage occurs at a joint, connection or component having a mechanical seal.
5.5 Poisson-Effect Expansion and Contraction—When test pressure is applied to plastic piping systems that have fully restrained joints such as heat fusion, electrofusion, bolted flanges, etc., either reduction of overall pipe length or an increase in longitudinal stress results from diametrical expansion of the pipe. Disjoining (pull-out) of partially restrained or non-restrained connections or joints, such as some in-line mechanical connectors having insufficient resistance to pull-out stress or length reduction, is possible when partially restrained or unrestrained joints are in-line with the fully restrained test section. To prevent Poisson-effect disjoining of partially restrained or non-restrained joints take measures such as installing external joint restraints (diametrical clamps and tie-rods) on...
SCOPE
1.1 This practice provides information on apparatus, safety, pre-test preparation, and procedures for conducting field tests of polyamide-12 (PA12) pressure piping systems after installation using gaseous testing media such as un-odorized inert non-toxic gas or air, and applying pressure to determine if leaks exist in the system (pneumatic leak testing). This practice applies only to testing to discover leakage. Testing for other purposes such as testing to establish operating pressure is beyond the scope of this practice.
1.2 Leak testing with pressurized gaseous testing media shall be used only if one or both of the following conditions exists:
1.2.1 The piping system is so designed that it cannot be filled with a liquid, or
1.2.2 The piping system service cannot tolerate traces of liquid testing media.
1.3 Where hydrostatic testing is specified in contract documents or by the authority having jurisdiction, testing using pressurized gaseous testing media (pneumatic) testing shall not be substituted without the express consent and authorization of the authority having jurisdiction.
1.4 Some manufacturers prohibit or restrict testing of their products with pressurized gaseous testing media. Contact component manufacturers for information. Where the manufacturer of a test section component prohibits or restricts testing with pressurized gaseous testing media testing in accordance with this practice shall not be used without the express consent and authorization of the authority having jurisdiction and the component manufacturer.
Note 1: Components that are not suitable for testing with gaseous testing media may not be suitable for service with pressurized gas.
1.5 This practice does not address leak testing using pressurized liquids (hydrostatic testing). For field leak testing using pressurized liquids, consult the manufacturer for guidance.
1.6 This practice does not apply to leak testing of non-p...

ABSTRACT
This specification covers the minimum performance and material requirements for a three piece tee connector for connection between plastic pipe and insitu pipes, manholes and wastewater structures in sanitary and storm sewer applications. The three piece seal system consists of a 4 through 30-in. PVC (polyvinyl chloride) hub pipe, an elastomeric seal (gasket) and a mechanical band. The system is installed in either a bored or cast hole opening in the host pipe or structure to a specific dimension that corresponds to the combined diameter of the PVC pipe outside diameter/tolerance and the elastomeric seal thickness. These tee connectors are designed to provide a non-pressure (gravity flow) watertight connection between the incoming pipe and an insitu pipe or manhole/structure to the limits defined in this standard. This specification deals with materials and manufacture, principles of design, basis of acceptance, test methods and requirements, rejection and rehearing, certification, markings, quality assurance, and packaging and package marking.
SCOPE
1.1 This specification covers the minimum performance and material requirements for a three piece tee connector for connection between plastic pipe and insitu pipes, manholes and wastewater structures in sanitary and storm sewer applications.
1.1.1 The three piece seal system consists of a 4 through 30-in. PVC (polyvinyl chloride) hub pipe, an elastomeric seal (gasket) and a mechanical band (Fig. 1). The system is installed in either a bored or cast hole opening in the host pipe or structure to a specific dimension that corresponds to the combined diameter of the PVC pipe outside diameter/tolerance and the elastomeric seal thickness.
FIG. 1 Three-Piece Sealing System (Connector)
1.2 These tee connectors are designed to provide a non-pressure (gravity flow) watertight connection between the incoming pipe and an insitu pipe or manhole/structure to the limits defined in this standard.
Note 1: Connections covered by this specification are adequate for laboratory hydrostatic pressures up to 13 psi (30 ft of head) without leakage when tested in accordance with the provisions of this standard. Infiltration or exfiltration quantities for an installed system are dependent upon many factors other than the connections between incoming pipe and the insitu pipe or manhole structure, and allowable quantities may need to be covered by other specifications and suitable testing of the installed pipeline and system. Where connections are made to concrete manhole sections refer to Specification C923.
Note 2: These connectors are not resilient connectors, and as such, allow for only a limited amount of lateral movement due to the tight compression seal between the PVC hub and insitu pipe/structure. Since these connectors are not rigid fittings, a significant amount of axial movement can be accommodated, but the degree of intrusion into the host pipe/structure must be regulated to minimize the impact on flow characteristics or hydraulic design conditions.
1.3 The following precautionary caveat pertains only to the test methods portion, Section 7, of this specification: 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. For a specific precaution statement, see Section 7.

SIGNIFICANCE AND USE
5.1 The values recorded are applicable only to the sewer joint being tested and at the time of testing.
SCOPE
1.1 This practice covers procedures for testing single joints of thermoplastic pipe for gravity flow (non-pressure) sewer lines, when using either air or water under low pressure to demonstrate the integrity of the joint. This practice is used for testing 27 in. (675 mm) and larger inside diameter PVC (Polyvinyl Chloride), HDPE (High Density Polyethylene) and PP (Polypropylene) sewer lines utilizing flexible gasketed joints with elastomeric seals, Specification F477.
1.2 This practice is used for assessing the watertight integrity of a joint at the time of the test. It is not a pipeline acceptance test as it does not evaluate the integrity of the pipe barrel or any long-term pipeline deformation effects from backfill settlement
Note 1: The user of this practice is advised that methods described herein is typically used as a preliminary test to enable the installer to demonstrate the integrity of a sewer pipe joint prior to placement of final backfill. Such testing after initial backfill can detect if a gasket has rolled or dirt was pushed into the joint during the mating of the pipe. Repair of these types of installation problems can be done very quickly and effectively prior to final backfill, but once final backfill is placed, repairs are very difficult and costly.
Note 2: This practice may be used at any time to check the integrity of a joint prior to acceptance testing or to locate a leaking joint when a pipeline fails a hydrostatic infiltration/exfiltration test, vacuum test or air pressure test during any time of the installation and acceptance process.
Note 3: The user of this practice is advised that no correlation has been found between air loss and water leakage.
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 Many of the tests that have been employed in the past to evaluate thread sealant products have not consistently targeted the most significant product features of a thread sealant. For instance, one of a thread sealant's primary performance features is its ability to maintain a seal under a range of conditions. The procedures in this test method assess the important characteristic properties of a thread sealant.
5.2 Because of the variability of the test specimens and the techniques employed by each operator, the assembly and test procedures and the testing apparatus have been designed to reduce the variability of the test results.
SCOPE
1.1 This test method covers procedures used to assemble, evaluate and test pipe thread sealants.
1.2 Test procedures included in this test method are cure speed versus temperature, primer cure, instant seal/sealability, heat aging, solvent resistance, hot strength, steam resistance, and specimen preparation for high pressure testing.
1.3 The values stated in inch-pound 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.
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
5.1 This practice determines the room temperature gasket constants Gb and a for initial seating and Gs for operating conditions as related to the tightness behavior of pressurized bolted flanged connections. These constants are used in determining the design bolt load for gasketed bolted joints.
5.2 This practice is suitable for all the types of gaskets and facings as are considered by the ASME Division 1 Code. This includes ASME B16.5 raised facings, nubbin-type facings, O-ring grooves, and a wide variety of gaskets including spiral wound, flat sheet, solid metal, jacketed, and other types of gaskets common to process and power industry pressurized equipment.
5.3 These constants are intended for direct use in determining ASME Code design calculations for bolted flanged joints. An appendix of the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1 will refer to the gasket constants Gb, a, and Gs produced by this practice. The user and bolted joint designer are cautioned that gasket constants Gb, a, and Gs and any gasket design stresses calculated from these may not be conservative for design stresses below S1 or beyond S13 as indicated in Table 3.
5.4 When required, this practice evaluates both the mechanical and leakage resistance of gaskets to excessive compression to determine their maximum assembly stress, Sc.
5.5 This test procedure is a gasket tightness characterization test and is not considered as a gasket manufacturing quality control test.
SCOPE
1.1 This practice determines room temperature gasket tightness design constants for pressurized bolted flanged connections such as those designed in accordance with the ASME Boiler and Pressure Vessel Code.
1.2 This practice applies mainly to all types of circular gasket products and facings typically used in process or power plant pressure vessels, heat exchangers, and piping including solid metal, jacketed, spiral wound, and sheet-type gaskets. As an optional extension of this practice, the maximum assembly stress for those gaskets may also be determined by this procedure.
1.3 Units—The values stated in SI units are to be regarded as the standard, but other units may be included.
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.

IEC 62339-1:2006 establishes properties and physical dimensions that define the interface for surface-mount fluid distribution components with elastomeric sealing devices used within process analyser and sample-handling systems. The interface controls the dimensions and location of the sealing surfaces to allow change of just one element of the system without modification of the entire system. This is what makes the system modular from both a design and a maintenance standpoint. It cancels and replaces IEC/PAS 62339-1 published in 2003. This first edition constitutes a technical revision.
