A sample weight of 10 to 15 mg is required. 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 ast, for checking plastic parts or resins for contamination not seen by FTIR.
Further d347 areas include determining the effect of light on the shelf life of foods or technical oils, fats and lubricants. The resulting thermal scan is then analyzed. This standard is not included in any packages. It unites excellent performance and highest flexibility. You may delete a document from your Alert Profile at any time. The sample compartment is where an encapsulated sample of about 10 to aztm milligrams is placed for testing. Standards can be obtained from appropriate standards authorities.
This test method covers the determination of heat of fusion and heat of crystallization of polymers by differential scanning calorimetry.

Differential Scanning Calorimetry (DSC)
All NETZSCH DSC instruments work in accordance with the heat-flux principle and feature high detection sensitivity and long service lives — ideal conditions for successful application in research d417 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. Note 2-This test method may not be applicable to all types of polymers as written see 6.
Subscription pricing is determined by: Using a DSC asstm scanning calorimeter the following are commonly determined: The sample is heated at e3417 controlled rate and a plot of heat flow versus temperature is produced.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of d33417 limitations prior to use.
Designed especially for the characterization of polymer materials, its integral approach consists not only of the DSC instrument alone, but also incorporates the entire analytical process chain from sample preparation to evaluation.
