Scope of standard 1.1 This test method determines the resistance of polyethylene materials to slow crack growth under conditions specified within.1.2 The test is generally performed at 80oC and at 2.4 MPa, but may also be done at temperatures below 80oC and with other stresses low enough to preclude ductile failure and thereby eventually induce brittle type of failure. Generally, polyethylenes will ultimately fail in a brittle manner by slow crack growth at 80oC if the stress is below 2.4 MPa.1.3 The test method is for specimens cut from compression molded plaques. See Appendix X1 for information relating to specimens from pipe.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.
