Standards Subsctiption may be the perfect solution. Note 1—True satm of fusion are to be determined in conjunction with structure investigation, and frequently, specialized crystallization techniques are needed. Link to Active This link will always route to the current Active version of the standard. When less energy is required to heat the sample as compared to the inert reference, an exothermic peak is observed.
Differential scanning calorimetry is used to assist in identifying specific polymers, polymer alloys, and certain polymer additives, which exhibit thermal transitions.

Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. This test method does not apply to all types of polymers as written see 6.
Due to copyright restrictions, we are not able to provide copies of standards. The ISO procedures provide additional information not supplied by this test method. Like all e3418, this technique tracks the amount of energy required to increase the temperature of a material by a certain amount.
Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world. 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.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. 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.

Need help or have a question? Weak glass transitions such as in polyethylene and polypropylene are usually not strong enough to detect.
Element d34118 a variety of methods for determining glass transition temperature and other important polymeric characteristics. To perform DSC testing, a small amount of material is heated at a predetermined rate.
