1.1 This practice covers the compression molding of thermoplastic granules and milled stock for the preparation of test specimens.
1.2 While conditions for certain materials are given, the primary source of specific conditions shall be the material specification standards for each type of material.
1.3 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 and health practices and determine the applicability of regulatory limitations prior to use.
