DSC testing has been used for decades as a way to predict the behaviors of polymeric materials under different thermal conditions. The peak of an endotherm indicated melting temperature. Link to Active This link will always route to the current Active version of the standard. Combined with an FTIR analysis, a DSC thermal 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.

Differential Scanning Calorimetry (DSC) Analysis
Using a DSC differential scanning calorimeter the following are commonly determined: Proceed to Checkout Continue Shopping. The ISO procedures provide additional information not supplied by this test method. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
One of the pans is filled with sample and the other is kept empty as a control. To perform DSC testing, a small amount of material is heated at a predetermined rate. Contact us for a quote. This may indicate a chemical reaction such as curing is taking place. The sample compartment is where an encapsulated sample of about 10 to 15 milligrams is placed for testing.

Send us a request Need help or have a question? 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. Both pans are heated at the same temperature ramp rate and the energy required to keep each one heating is continuously measured.

ASTM D3418 – MELTING POINT BY DSC TESTING SERVICES
The signal from the DSC is usually plotted with temperature on the X-axis and heat energy on the Atm. Differential scanning calorimetry is used to assist in identifying specific polymers, polymer alloys, and certain polymer additives, which exhibit thermal transitions.
