This document specifies the housing dimensions for class A O-rings for general industrial applications conforming to ISO 3601-1, as well as housing dimensions for class B O-rings used on selected metric-dimensioned hardware, e.g. fluid power cylinder bores and piston rods. These O-rings are for use in general hydraulic and pneumatic applications without and with anti-extrusion rings (back-up rings). The dimensions of the O-rings (d1 and d2), size codes (SC) and tolerances conform to ISO 3601-1. This document also addresses different design approaches in industry, and this is reflected in the table structures for hardware dimensions. Using the O-ring as a starting point to design the optimal hardware dimensions is reflected in REF Table_tab_3 \r \h Tables 3 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000C0000005400610062006C0065005F007400610062005F0033000000 , REF Table_tab_5 \r \h 5 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000C0000005400610062006C0065005F007400610062005F0035000000 , and REF Table_tab_8 \r \h 8 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000C0000005400610062006C0065005F007400610062005F0038000000 .

SIGNIFICANCE AND USE
4.1 When more than one elastomer seal material is tested, the test methods yield comparative data on which to base judgements as to expected service quality. Suggested in-service property change limits are provided. Property changes beyond these limits will indicate limited service life of the elastomer seal.
4.2 These test methods attempt to simulate service conditions through controlled aging and evaluation of property changes but may not give any direct correlations with actual part performance since actual service conditions vary widely. These test methods yield comparative data and indications of property changes of the elastomeric seal material under ideal service conditions. These test methods can be used for quality control purposes, for engineering assessments, for service evaluation, and for manufacturing control. The information from these test methods can be used to anticipate expected service quality.
SCOPE
1.1 These test methods cover the procedure for measuring physical properties of elastomer seals in the form of O-rings after exposure to industrial hydraulic fluids and thermal aging. The measured properties are then compared to the physical properties of elastomer seals that have not been exposed to the industrial hydraulic fluids and thermal aging. The changes in these properties form a basis for assessing compatibility when these changes are compared against the suggested limits in Table 1.
1.2 While these test methods involve the use of O-rings, they can also be used to evaluate the compatibility of the elastomeric compounds of specialty seals with industrial hydraulic fluids and their resistance to thermal aging. The compounds can be molded into O-rings for evaluation purposes.
1.3 These test methods provide procedures for exposing O-ring test specimens to industrial hydraulic fluids under definite conditions of temperature and time. The resulting deterioration of the O-ring material is determined by comparing the changes in work function, hardness, physical properties, compression set, and seal volume after immersion in the test fluid to the pre-immersion values.

SIGNIFICANCE AND USE
5.1 Many sealants have been observed to dimensionally change following a period of compression or tension, such as occurs during exposure in accordance with Practice C1589. It has been shown that for some sealants, increasing exposure to weathering increases the time required for dimensional stability and decreases the magnitude of dimensional change. Dimensional stability and knowledge of the stable sealant dimensions are critical to the accurate measurement of the sealant’s modulus by a test such as Test Method C1735.
5.2 This practice will find application in improving the accuracy of the modulus determined by a standard such as Test Method C1735 by using the accurate dimensions determined by this practice after stability is attained.
SCOPE
1.1 This practice covers a procedure for measuring and monitoring the physical dimensions of an elastomeric joint sealant in a test specimen configuration described in Test Method C719 following a period of compression or tension. These sealant materials are typically highly filled elastic materials. The dimensional change of these sealant materials is determined by measuring the dimensions at specific intervals over a period of time.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units 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.

SIGNIFICANCE AND USE
4.1 Sealants are supplied with various rheological properties ranging from pourable liquids to nonsagging pastes. Single-component sealants are supplied ready for use upon opening the container. Multicomponent sealants are supplied as a base component(s) and a curing agent separately packaged. After mixing the two or more parts, the sealant is ready for application. This test method is intended to provide a means to measure the extrusion rate spanning the range of rheological properties.
4.2 This test method also covers the option of measuring the freeze-thaw and heat stability of such sealants.
4.3 This test method provides for an option of either a metal or plastic nozzle. It is intended that the metal nozzle be used when greater precision is required, such as in ASTM specifications. The plastic nozzle may be used for general screening of sealant properties or for developmental purposes when a large number of test specimens are being tested.
4.4 This test method measures the volume of sealant extruded over a given period of time at a given pressure (kPa or psi).
SCOPE
1.1 This test method covers two laboratory procedures for determining the extrusion rate of elastomeric sealants for use in building construction.
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 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.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

ISO 9631:2018 specifies material requirements for vulcanized rubber seals for hot drinking and non-drinking water supply (up to 110 °C). The different seal designations specified are defined according to seal type, seal application and the requirements for a particular seal (see Table 2). General requirements for finished joint seals are also given. Any additional requirements called for by the particular application are specified in the relevant product standards, taking into account that the performance of pipe joints is a function of the seal material properties, seal geometry and pipe joint design. This document is intended to be used where appropriate, in conjunction with product standards which specify performance requirements for joints. ISO 9631:2018 is applicable to joint seals for use with all pipeline materials, including metals, clay, fibre cement, concrete, reinforced concrete, plastics and glass-reinforced plastics. ISO 9631:2018 is applicable to elastomeric components of composite and non-composite seals. In the case of composite seals made from materials with hardness ranging from 76 IRHD to 95 IRHD, the requirements for elongation at break, compression set and stress relaxation apply only when the material participates in the sealing function or contributes to the long-term stability of the seal. The material requirements specified in this document are designed for long term performances and a potential lifetime of 50 years. The lifetime of a sealing depends not only on material performance but also on other parameters which are not defined in this document like the mounting design, the quality of assembly and the combination with operating conditions. Joint rings made from cellular rubber materials are not covered by this document.

ABSTRACT
This specification covers the material requirements for preformed elastomeric strip seals and the corresponding steel locking edge rail used in expansion joint sealing. The scope of this specification is limited to preformed non-reinforced strip seals that mechanically lock into structural steel locking lugs. The sealing element can consist of a single layer strip or have multiple webs depending on individual project requirements. When used on highway bridges, limits on maximum joint opening and minimum steel thicknesses need to be addressed. The adhesive-lubricant used to install the preformed seal into the steel locking edge rail shall be a one part moisture curing polyurethane compound. The elastomeric seals shall conform to the physical properties prescribed for (1) tensile strength, (2) elongation at break, (3) hardness, (4) oven aging, (5) oil swell, (6) ozone resistance, (7) low temperature stiffening, and (8) compression set. Requirements for preformed elastomeric seal dimensions, sampling, and test methods to determine compliance with the specified physical properties are given.

ABSTRACT
This specification covers the material requirements for preformed thermoplastic vulcanizate (TPV) elastomeric joint seals for bridges. The seal consists of a multiple-web design composed of a TPV and functions only by compression of the seal between the faces of the joint with the seal folding inward at the top to facilitate compression. The seal is installed with a lubricant adhesive and is designed to seal the joint and reject incompressibles. The physical properties for which the seals shall be tested on and conform accordingly to are tensile strength, elongation at break, hardness, oven aging, ozone resistance, low- and high-temperature recovery, and compression-deflection properties.

This European Standard specifies the material requirements and test methods for prefabricated elastomeric seals for use in flue liners. It also specifies the requirements for evaluation of conformity.
These seals are components in flue liners of different materials such as metal, plastic, clay, concrete.
Performance requirements of elastomeric seals in flue liners are covered by the relevant product standards.
In the product standards, chimney products, including seals, are tested under operational conditions (e.g. temperature, pressure, mechanical load, flue gas, condensate) to relevant properties such as leakage and deformation.
This European Standard covers seals intended for use in both dry and wet conditions. Therefore all seals are tested for functioning under wet conditions.
This European Standard does not contain all the requirements necessary for chimneys with the following classification:
- corrosion resistance class 2 concerning natural wood ),
- corrosion resistance class 3.
This European Standard is also applicable for sealants, in case nothing else is defined. The specimens are made from the sealants, which have been brought into a practical form, cured under manufacturers' instructions. The cured sealants will fulfil the same requirements as seals.
NOTE Cured sealants are operationally seals in application.
