ASTM D3418 Standard Test Method for Transition Temperatures and Enthalpies of Fusion and Crystallization of Polymers by Differential Scanning Calorimetry

This standard covers the crystallization of polymers and the determination of their transition temperatures and fusion enthalpies by differential scanning calorimetry. The actual heats of fusion will be determined in conjunction with the structure investigation, and special crystallization techniques are often required.

ASTM D3418 Standard Test Method for Transition Temperatures and Enthalpies of Fusion and Crystallization of Polymers by Differential Scanning Calorimetry

This standard is applicable to polymers in granular form or to any fabricated shape where it is possible to cut suitable samples.

The normal operating temperature range is from the cryogenic zone to 600°C. Some equipment allows the temperature range to be extended.

Values ​​stated in SI units are standard.

This standard does not apply to all polymer types as written


This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.
