ASTM E2038-99(2004)

Отменен
Standard Test Method for Temperature Calibration of Dielectric Analyzers (Withdrawn 2009) — 4 стр.
Причина отмены

This test method describes the temperature calibration of dielectric analyzers over the temperature range from 100 to 300 °C and is applicable to commercial and custom-built apparatus.

Formerly under the jurisdiction of Committee E37 on Thermal Measurements , this test method was withdrawn in September 2009 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Значение и использование

This test method permits interlaboratory comparison and intralaboratory correlation of instrumental temperature scale data.

Dielectric analyzers are used to characterize a broad range of materials that possess dielectric moments. One of the desired values to be assigned by the measurement is the temperature at which significant changes occur in the properties of the test specimen. In order to obtain consistent results from one period of time to another and from one laboratory to another, the temperature signal from the apparatus must be calibrated accurately over the temperature range of interest.

Область применения

1.1 This test method covers the temperature calibration of dielectric analyzers over the temperature range from -100 to 300°C and is applicable to commercial and custom-built apparatus. The calibration is performed by observing the melting transition of standard reference materials having known transition temperatures within the temperature range of use.

1.2 Electronic instrumentation or automated data analysis and data reductions systems or treatment equivalent to this test method may be used.

1.3 The values stated in SI units are to be reported as the standard.

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 to determine the applicability of regulatory limitations prior to use.
