(Specification)Standard Specification for Rubber Gaskets for Cast Iron Soil Pipe and Fittings
Standard Specification for Rubber Gaskets for Cast Iron Soil Pipe and Fittings
ABSTRACT
This specification covers preformed rubber gaskets used to seal joints in cast iron soil pipe and fittings. Gaskets shall be made of a properly vulcanized virgin rubber as the sole elastomer with no scrap or reclaim. Gaskets shall conform to the required physical properties such as hardness, elongation, tensile strength, tear strength and compression. The gasket material shall be tested for effects of heat aging. They shall be tested for weight increase due to water absorption and shall also be tested for volume decrease due to oil absorption. Gasket material shall be tested for ozone resistance.
SCOPE
1.1 This specification covers preformed rubber gaskets used to seal joints in cast iron soil pipe and fittings.
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 The following safety hazards caveat pertains only to the test methods section 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 and health practices and determine the applicability of regulatory limitations prior to use.
1.4 The committee with jurisdiction over this standard is not aware of another comparable standard for materials covered in this standard.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
