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 the 12454 compound as described in Specification D1784 and a 4,000 HDB shall be obtained by categorizing the LTHS in accordance with Table 1 in Test Method D2837. That includes, but is not limited to, pipe produced in accordance with the following standards: Specifications D1785 and D2241, and AWWA C900. 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. 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. 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.
