Description

ASTM E1640-04

Historical Standard: Standard Test Method for Assignment of the Glass Transition Temperature By Dynamic Mechanical Analysis

ASTM E1640

Scope

1.1 This test method covers the assignment of a glass transition temperature (Tg) of materials using dynamic mechanical analyzers.

1.2 This test method is applicable to thermoplastic polymers, thermoset polymers, and partially crystalline materials which are thermally stable in the glass transition region.

1.3 The applicable range of temperatures for this test method is dependent upon the instrumentation used, but, in order to encompass all materials, the minimum temperature should be about -150°C.

1.4 This test method is intended for materials having an elastic modulus in the range of 0.5 MPa to 100 GPa.

1.5 Electronic instrumentation or automated data analysis and data reduction systems or treatments equivalent to this test method may also be used.

Note 1—The user bears the responsibility for determining the precision, accuracy, and validity of the techniques and measurements made using dynamic mechanical analyzers in accordance with this standard.

1.6 SI units are the standard.

1.7 This standard is similar to IEC 61006 except that standard uses the peak temprature of the mechanical loss peak as the glass transition temperature while this standard uses the extrapolated onset temperature of the loss modulus change.

1.8 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 determine the applicability of regulatory limitations prior to use.
