1.1 This test method determines the resistance of polyethylene materials to slow crack growth under conditions specified within.
Note 1This test method is known as PENT (Pennsylvania Notch Test) test.
1.2 The test is generally performed at 80C and at 2.4 MPa, but may also be done at temperatures below 80C 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 80C 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.
