|Publication Date:||24 November 1989|
|ICS Code (Films and sheets):||83.140.10|
1.1 This test method is intended to measure batch-to-batch uniformity in initial shrinkage from mold to molded dimensions of either thermoplastic or thermosetting materials when molded by compression, injection, or transfer under specified conditions.
1.2 This test method does not provide for the measurement of shrinkages that may occur as molded materials age, after the first 48 h out of the mold.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
