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.

Using a DSC differential scanning calorimeter the following are commonly determined: This may indicate a chemical reaction such as curing is taking place. Contact us for a quote. This test method does not apply to all types of polymers as written see 6.
A 3d418 weight of 10 to astn mg. Both pans are heated at the same temperature ramp rate and the energy required to keep each one heating is continuously measured.

Differential Scanning Calorimetry Analysis – DSC – ASTM D, ASTM D | Element
The d418 compartment is where an encapsulated sample of about 10 to 15 milligrams is placed for testing. The signal from the DSC is usually plotted with temperature on the X-axis and heat energy on the Y-axis.
Chemical reactions that cause or affect certain transitions have been measured with the aid of this technique; such reactions include oxidation, curing of thermosetting resins, and thermal decomposition.
