1.1This test method covers determination of transition temperatures and enthalpies of fusion and crystallization of polymers by differential scanning calorimetry.
Note 1:True heats of fusion are to be determined in conjunction with structure investigation, and frequently, specialized crystallization techniques are needed.
1.2This test method is applicable to polymers in granular form or to any fabricated shape from which it is possible to cut appropriate specimens.
1.3The normal operating temperature range is from the cryogenic region to 600°C. Certain equipment allows the temperature range to be extended.
1.4The values stated in SI units are the standard.
Note 2:This test method does not apply to all types of polymers as written (see 6.8).
1.5This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 3:This standard is similar but not equivalent to ISO 11357-1, -2, -3. The ISO procedures provide additional information not supplied by this test method.
1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
