This test method covers the determination of heat of fusion and heat of crystallization of polymers by differential scanning calorimetry. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Characteristic temperatures melting, crystallization, polymorphous transitions, reactions, glass transition Melting, crystallization, transformation and reaction heats enthalpies Crystallinity of semi-crystalline substances Decomposition, thermal stability Oxidative stability OIT, OOT — oxidative-induction time and oxidation onset temperature, respectively Degree of curing in resins, adhesives, etc.
A sample weight of 10 to 15 mg is required. Play Differential Scanning Calorimeter Video. The reference compartment contains an empty aluminum pan and cover equivalent to those used to encapsulate a test sample.
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.

Differential Scanning Calorimetry (DSC) / Differential Thermal Analysis (DTA)
Note 4- To date, there is no similar or equivalent approved ISO standard. Due to copyright restrictions, we are not able to provide copies of standards.
The sample is heated at a controlled rate and a plot of heat flow versus temperature is produced. All NETZSCH DSC instruments work in atm with the heat-flux principle and feature high detection sensitivity and long service lives — ideal conditions for successful application in research and academia, material development and quality control. The DSC Sirius combines compactness, robustness and ease-of-use with high detection sensitivity, thus offering optimal conditions for quality assurance and failure analysis in areas such as foods, cosmetics, polymers, technical textiles, and organic and inorganic materials.

The resulting thermal scan is then analyzed. Combined with an FTIR analysisa 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. Further application areas include determining the effect of light on the shelf life of foods or technical oils, fats and lubricants.
Due to its versatility and the high significance of its analytical output, differential scanning calorimetry DSC is the most often employed method for thermal analysis.
