ASTM D3418 – MELTING POINT BY DSC TESTING SERVICES
Note 3—This standard is similar but not equivalent to ISO-2, When less energy is required to heat the sample as compared to the inert reference, an exothermic peak is observed. Weak glass transitions such as in polyethylene and polypropylene are usually not strong enough to detect. Differential scanning calorimetry is used to assist in identifying specific polymers, polymer alloys, and certain polymer additives, which exhibit thermal transitions.
Add to Alert PDF. Element offers a variety of methods for determining glass transition temperature and other important polymeric characteristics. As the voice of the U.
Please first verify your email before subscribing to alerts. The energy required to heat the sample is compared to an inert reference material at the same temperature. Both pans are heated at the same temperature ramp rate and the energy required to keep each one heating is continuously measured.
One of the pans is filled with sample and the other is kept empty wstm a control.

Note 2—This test method does not apply to all types of polymers as written see 6. Using a DSC differential scanning calorimeter the following are commonly determined: 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.
It is asm responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
