1.1 This test method covers the determination of melting (and crystallization) temperatures of pure materials by differential scanning calorimetry (DSC) and differential thermal analysis (DTA). 1.2 This test method is generally applicable to thermally stable materials with well-defined melting temperatures. 1.3 The normal operating range is from -120 to 600°C for DSC and 25 to 1500°C for DTA. The temperature range can be extended depending upon the instrumentation used. 1.4 Computer or electronic based instruments, techniques, or data treatment equivalent to those in this test method may be used. 1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.6 This standard does not purport to address all of the safety problems, 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.
