1. Scope

1.1 This test method describes a procedure for qualifying the performance of joint restraint products for use on PVC pressure pipe systems by evaluating the effect of the joint restraint product on the performance characteristics of PVC pipe during cyclic pressure tests and static pressure tests. The PVC pipe property values referenced in this test method are for Compounds 12454A and 12454B as described in Specification D1784. That includes, but is not limited to, pipe produced in accordance with the following standards:Specifications D1785 and D2241, AWWA C900, and AWWA C905.

1.2 This test method determines the short-term performance of a joint restraint product on PVC pipe, which involves the testing of restrained joint test sections to the minimum burst pressure requirements of the pipe to determine quick burst performance.

1.3 This test method determines the long-term effect of a joint restraint product on PVC pipe, which involves the testing of restrained joint test sections to the sustained pressure requirements of the pipe for a period of 1000 h.

1.4 This test method addresses restraint products that are rated at the full pressure capacity of the PVC pipe on which they are used. There are joint restraint devices available that are not rated at the full pressure capacity of the pipe. While those products have proven acceptable and useful in the marketplace, this test method does not apply to those products.

1.5 This test method determines the performance of a joint restraint product on PVC pipe subjected to cyclic pressure surges. The performance is compared to the baseline performance of pipe without joint restraint products established by Herbert W. Vinson.

1.6 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information purposes only.

1.7 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.
