It is also used to characterize materials for their thermal performance. The ISO procedures provide additional information not supplied by this test method. Send us a request Wilton UK: The sample compartment is where an encapsulated sample of about 10 to 15 milligrams is placed for testing. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. One of the pans is filled with sample and the other is kept empty as a control.

This standard is also available to be included in Standards Subscriptions. Like all calorimeters, this technique tracks the amount of energy required to increase the temperature of a material by a certain amount. The resulting thermal scan is then analyzed. Measures the temperature and energy of thermal transitions such astmm melting point, glass transition, and curing reactions.

Auditing Consulting Sourcing Training. Differential scanning calorimetry is used to assist in identifying specific polymers, polymer alloys, and certain polymer additives, which exhibit thermal transitions.

Standards can be obtained from appropriate standards authorities. If the document is revised or amended, you will be notified by email. When less energy is required to heat the sample as compared to the inert reference, an exothermic peak is observed.

Link to Active This link will always route to the current Active version of the standard. Element offers a variety of methods for determining glass transition temperature and other important polymeric characteristics. This standard is not included in any packages.


Both pans are heated at the same temperature ramp rate and the energy required to keep each one heating is continuously measured. The signal from the DSC is usually plotted with temperature on the X-axis and heat energy on the Y-axis. 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.

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. The sample is heated at a controlled rate and a plot of heat flow versus temperature is produced.
