By making accurate measurements of heat capacity and temperature, differential scanning calorimetry can detect sstm in material properties at exact temperatures, revealing important transition ranges and deterioration points. Like all calorimeters, this technique tracks the amount of energy required to increase the temperature of a material by a certain d348. The ISO procedures provide additional information not supplied by this test method.

The peak of an endotherm indicated melting temperature. To perform DSC testing, a small amount of material is heated at a predetermined rate. Material testing you can trust since Note 3—This standard is similar but not equivalent to ISO-2, Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are xstm provided as part of the standard.
