5.1 This test method may be used for routine inspection purposes by subjecting a required number of specimens to the test conditions for a specified time and noting the number that fail. The cracking obtained with the test reagent is indicative of what may be expected from a wide variety of surface-active agents, soaps, and organic substances that are not absorbed appreciably by the polymer. 5.2 Environmental stress-cracking is a property that is highly dependent upon the nature and level of the stresses applied and on the thermal history of the specimen Condition |

5.3 Information from this test
method is not intended to be used for direct application to
engineering problems.
1.1 This test method covers the
determination of the susceptibility of ethylene plastics, as
defined in Terminology D883, to environmental stress-cracking when
subjected to the conditions herein specified. Under certain
conditions of stress and in the presence of environments such as
soaps, wetting agents, oils, or detergents, ethylene plastics may
exhibit mechanical failure by cracking.
1.2 The values stated in SI units are to be regarded as standard.
1.3 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.
