4.1 These procedures can be used to evaluate chemicals or materials expected to come in contact with plastic piping relative to causing environmental stress-cracking in thermoplastic materials. This testing results in determining time-to-failure versus engineering stress. This procedure can also be used in stress-rupture regression analysis, where a variety of stress levels are needed. The methodology can be readily adapted to conducting immersion tests in liquids or testing temperatures other than 73 °F (23 °C).View Less
1.1 This test method is used for determining chemical compatibility of substances in contact with thermoplastic pipe and fittings materials.
1.2 This test method is not intended to evaluate the suitability of solvent cements or adhesives used to join plastic piping.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
