Formally confirming that your products and services meet all trusted external and internal standards. The energy required to heat the sample is compared to an inert reference material at the same temperature. 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.

The sample is heated at a controlled rate and a plot of heat flow versus temperature is produced. When less energy is required to heat the sample as compared to the inert reference, an exothermic peak is observed.

This standard is not included in any packages. 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. Subscription pricing is determined by: Active view current version of standard. It is also used to characterize materials for their thermal performance.
