Significance and Use

5.1 The bias or offset temperature value provided by this practice may be used to calibrate or to evaluation the performance of standard, apparatus, technique, or software.

Note 2: Calibration or calibration verification is recommended for all signals at least annually.

5.2 The glass transition temperature is a function of heating rate. The observed values at a heating rate different from that of the calibration need to be assessed using thermal lag (see Test Method E3142).

Scope

1.1 It is the purpose of this practice to provide accepted reference values for the glass transition temperature that may be used for evaluation of dynamic mechanical analysis methods, apparatus, and software.

Note 1: Suggested additional or alternative reference materials or values are requested and may be submitted to the E37 Staff Manager at ASTM International, West Conshohocken PA for consideration.

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.
