ASTM E2425-21 PDF

Scope: 1.1 This test method describes the performance confirmation or measurement of conformance for the loss modulus scale of a commercial or custom-built dynamic mechanical analyzer (DMA) at 21 °C using ultra-high molecular weight polyethylene as a reference material. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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.
