Additional information
| Significance and Use | ||||||
|
5.1 This test method is useful to measure the slow crack growth resistance of molded plaques of polyethylene materials at accelerated conditions such as 80°C, 2.4-MPa stress, and with a sharp notch. 5.2 The testing time or time to failure depends on the following test parameters: temperature; stress; notch depth; and specimen geometry. Increasing temperature, stress, and notch depth decrease the time to failure. Thus, in reporting the test time or time to failure, all the conditions of the test shall be specified. |

|
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 80°C and at 2.4 MPa, but may also be done at temperatures below
80°C 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 80°C if the stress is below 2.4 MPa.
1.3 The test method is for specimens cut from compression molded plaques.2 See 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. |
