Standard Test Method for Linear Dimensional Changes of Plastics Caused by Exposure to Heat and Moisture

Significance and Use

4.1 This test method is intended only as a convenient test method for measurement of linear dimensional changes in plastics subjected to defined conditions of test as outlined in Sections 7 and 8.


1.1 This test method is designed to provide a means for measuring in plastic specimens the dimensional changes such as shrinkage or expansion, developed under specific heat and water conditionings.

1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered 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.
