This specification covers the two types of joints, mechanical joint and push-on-joint, required for plastic pipe pressure systems with a wall thickness equal to or greater than that of SDR 64 intended for use in supply and distribution lines for water using flexible elastomeric seals. The joint shall be designed to provide a permanent seal, with surfaces free of imperfections that could adversely affect its performance. Internal hydrostatic pressure and vacuum tests shall be conducted on the assembled joints under standard laboratory temperature and relative humidity conditions. The joint assemblies shall conform to the pressure rating, stiffness, and deflection requirements.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers the types of joints required for plastic pipe pressure systems with a wall thickness equal to or greater than that of SDR 64 and intended for use in supply and distribution lines for water, using flexible elastomeric seals. This specification covers the test requirements, test method, and materials. The test methods described are not intended to be routine quality control tests, but are to evaluate the performance characteristics of the joint.

1.2 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.

1.3 The following safety hazards caveat pertains to the test method portion, Section 6, 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
