ASTM D7999-15 PDF

Scope: 1.1 This classification system covers the properties of vulcanized rubber materials (natural rubber, reclaimed rubber, synthetic robbers, alone or in combination) that are intended for use in rubber products found in natural gas pipeline applications (for example, elastomeric couplings, o-rings, quad seals, and diaphragms).

1.2 This classification system is based on the premise that the material properties of all rubber products can be arranged into characteristic material designations. These designations are determined by types and classes as described in Classification System D2000. For gas industry pipeline applications, materials can be further described using additional requirements herein in conjunction with Classification System D2000. It must be noted that there are other types of elastomers covered in Classification System D2000 that are not covered by this standard.

1.3 In all cases where the provisions of this classification system would conflict with those of the detailed specifications for a particular product, the latter shall take precedence.

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 and health practices and determine the applicability of regulatory limitations prior to use.
