Qstm polymer testing experts have years of experience across a variety of industries, and can help you overcome the unique challenges inherent with non-metallic materials. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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. This test method does not apply to all types of polymers as written see 6. Active view current version of standard Translated Standard: Element offers a variety of methods for determining glass transition temperature and other important polymeric characteristics.

Differential Scanning Calorimetry Analysis – DSC – ASTM D, ASTM D | Element
Doing business with one of our laboratories enables our clients’ access to our global platform of expertise, capacity and capabilities. Due to copyright restrictions, we are not able to provide copies of standards. A sample weight of 10 to 15 mg. 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 d4318 FTIR.
Certain equipment allows the temperature range to be extended.
True heats of fusion are to be determined in conjunction with structure investigation, and frequently, specialized crystallization techniques are needed.
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 also used to characterize materials for their thermal performance. Like all calorimeters, this technique tracks the amount of energy required to increase the temperature of a material by a certain amount.
The peak of an endotherm indicated zstm temperature. Note 2—This test method does not apply to all types of polymers as written see 6. Proceed to Checkout Continue Shopping.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Material testing you can trust since Note 3—This standard is similar but not equivalent to ISO-2, Phenolic materials typically give off water as a by product of curing which boils and shows a downward endothermic peak in the same range as the curing exothermic peak so they cancel each other out.

We have asgm amendments or corrections for this standard. Differential Scanning Calorimetry, commonly known as DSC, is a thermo-analytical technique for polymeric and non-metallic materials.
The pan filled with sample will require extra energy to heat through d34188 transition such as a melting point because extra energy is required to change the molecule from a solid to a molten state. The reference compartment contains an empty aluminum pan and cover equivalent to those used to encapsulate a asstm sample. Melting or boiling points look like a downward endothermic peak since they absorb energy, glass transitions look like a stair step, and most curing reactions show an upward exothermic peak.
E Terminology Relating to Thermophysical Properties. Certain equipment allows the temperature range to asym extended. Standards can be obtained from appropriate standards authorities.
