The DSC head area contains equivalent sample and reference compartments located adjacent to each other.


One of the pans is filled with sample and the other is kept empty as a control. This standard is not included in any packages.

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. Melting or boiling points look like a downward endothermic peak since they absorb energy, glass transitions look like a stair step, and most curing reactions show an upward astmm peak.

Phenolic materials typically give off water as a by v3418 of curing which boils and shows a downward endothermic d34188 in the same range as the curing exothermic peak so they cancel each other out. Our polymer testing experts have years of experience across a variety of industries, and can help you overcome the unique challenges inherent with non-metallic materials.

The ISO procedures provide additional information not supplied by this test method. Combined with an Asstm analysis, a DSC asmt scan can be used to help further identify certain types of materials by their melting points and is a useful tool for checking plastic parts or resins for contamination not seen by FTIR.

Note 2—This test method does not apply to all types of polymers as written see 6. Add to Alert PDF. Contact an expert today to let us know how we can make your next project a success.

Active view current version of standard. Your Alert Profile lists the documents that will be monitored. The peak of an endotherm indicated melting temperature.


Weak glass transitions such as in polyethylene and polypropylene are usually not strong enough to detect. Element offers a asmt range of experience in consulting, analytical testing, and industrial chemistry.

By making accurate measurements of heat capacity and temperature, differential scanning calorimetry can detect changes in material properties at exact temperatures, revealing important transition ranges and deterioration points.


Certain equipment allows the temperature range to be extended. This standard is also available to be included in Standards Subscriptions. As the voice of the U.

Differential Scanning Calorimetry Analysis – DSC – ASTM D, ASTM D | Element

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 is used to assist in ast specific polymers, polymer alloys, and certain polymer additives, which exhibit thermal transitions. Please first log in with a verified email before subscribing to alerts. The pan filled with sample will require extra energy to heat through a transition such as a melting point because extra energy is required to change the molecule from a solid to a molten state.

The signal from the DSC is usually plotted with temperature on the X-axis and heat energy on the Y-axis. You may delete a document from your Alert Profile at any time. The reference compartment contains an empty aluminum pan and cover equivalent to those used to encapsulate a test sample.
