ASTM E1867-22

5.1?Dynamic mechanical analyzers monitor changes in the viscoelastic properties of a material as a function of temperature and frequency, providing a means to quantify these changes. In most cases, the value to be assigned is the temperature of the transition (or event) under study. Therefore, the temperature axis (abscissa) of dynamic mechanical analysis thermal curves must be accurately calibrated by adjusting the apparent temperature scale to match the actual specimen temperature over the temperature range of interest.

5.2?This test method is useful for research, quality assurance, and specification acceptance.

1.1?These test methods describe the temperature calibration of dynamic mechanical analyzers (DMA) from 100 ?C to 300 ?C.

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.
