DSC testing has been used for decades as a way to predict the behaviors d33418 polymeric materials under different thermal xstm. Active view current version of standard Translated Standard: Most commonly used for detecting glass transition temperature and other thermal properties, differential scanning calorimetry is one of the most efficient and cost-effective polymer test methods available. Link to Active This link will always route to the current Active version of the standard.

Differential Scanning Calorimetry, aastm known as DSC, is a thermo-analytical technique for polymeric and non-metallic materials. Engage with an expert today. Need more than one copy? If the sample under test requires more energy compared to the reference, it is indicated as an endotherm.

Differential Scanning Calorimetry (DSC) Analysis

The peak of an endotherm indicated melting temperature. Using a DSC differential scanning calorimeter the following are commonly determined: Validating the specifications, value xstm safety of your raw materials, products and assets.

Note 2—This test method does not apply to all types of polymers as written see 6. E Terminology Relating to Thermophysical Properties. 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.

Historical Version s – view previous versions of standard. Element offers a variety of methods for determining glass transition temperature and other important polymeric characteristics. This difference in energy is recorded as a astk on the DSC scan which indicates the temperature and energy of the transition.

Certain equipment allows the temperature range to be extended. Weak glass transitions such as in polyethylene and polypropylene are usually not strong enough to detect.

Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Formally confirming that your products and services meet all trusted external and internal standards. This test method does not apply to all types of polymers as written see 6. The DSC head area contains equivalent sample and reference compartments located adjacent to each other.

Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
