Like all calorimeters, this technique tracks the amount of energy required to increase the temperature of a material by a certain amount. Formally confirming that your products and services meet all trusted external and internal standards. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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. Material testing you can trust since 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 by FTIR.

Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Advanced Plastic and Material Testing, Inc. Standards Subsctiption may be the perfect solution. Certification Formally confirming that your products and services meet all trusted external and internal standards.

To perform DSC testing, a small amount of material is heated at a predetermined rate. Certain equipment allows the temperature range to be extended.

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.

Auditing Consulting Sourcing Training. One of the pans is filled with sample and the other is kept empty as a control. 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.

Our deliverable is certainty – high quality data, test reports and certifications that you can rely on when making decisions about your materials and components.

Certain equipment allows the temperature range to be extended. 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.

Please first verify your email before subscribing to alerts.

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.

The energy required to heat the sample is compared to an inert reference material at the same temperature. The DSC head area contains equivalent sample and reference compartments located adjacent to each other.
