Thermal analysis provides a rapid method for determining transition temperatures in HC resins that possess them.

This practice is useful for both quality assurance and research.

1.1 This practice covers determination of glass transition temperatures of hydrocarbon (HC) resins by differential scanning calorimetry (DSC).

1.2 This practice is applicable to HC resins as defined in Terminology D6440. The normal operating temperature range is from the cryogenic region to approximately 180^oC. The temperature range can be extended.

1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

1.4 Further discussion of glass transition can be found in Test Method D3418, and Test Method E1356.

1.5 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.
