Description / Abstract:

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

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

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.

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

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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

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.
