This test method describes the determination of the enthalpy (heat) of fusion (melting) and crystallization by differential scanning calorimetry (DSC). This test method is applicable to solid samples in granular form or in any fabricated shape from which an appropriate specimen can be cut, or to liquid samples that crystallize within the range of the instrument. Note, however, that the results may be affected by the form and mass of the specimen, as well as by other experimental conditions. The normal operating temperature range is from -120 to 600°C. The temperature range can be extended depending upon the instrumentation used. This test method is generally applicable to thermally stable materials with well-defined endothermic or exothermic behavior.
WJE laboratories are accredited by ANAB (ISO/IEC 17025) to perform testing standard ASTM E793 for Enthalpies of Fusion and Crystallization by Differential Scanning Calorimetry.
