Significance and Use
This test method is intended for use as a control, acceptance, and assessment test.
Moisture can seriously affect the processability of plastics. It is possible that high moisture content will cause surface imperfections (that is, splay or bubbling) or degradation by hydrolysis. Low moisture (with high temperature) has been known to cause solid phase polymerization.
The physical properties of some plastics are greatly affected by the moisture content.
Scope
1.1 This test method covers the quantitative determination of moisture by means of loss in weight technology down to 50 ppm as it applies to most plastics.
1.2 The values stated in SI units are to be regarded as the standard.
1.3 Specimens tested in this method can reach or exceed 250C, use caution when handling them after testing has been completed.
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.
