ASTM D6980-25

1.1 This test method covers the quantitative determination of moisture by means of loss in weight technology down to 50 mg/kg (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 by this method will be hot, 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, 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.

5.1 This test method is intended for use as a control, acceptance, and assessment test.

5.2 Moisture will affect the processability of some materials. For these materials, defects will occur if they are processed with a moisture content outside of the recommended range. This test method does not identify any components.

5.3 The physical properties of some plastics are greatly affected by the moisture content.
