Differential Scanning Calorimetry

Differential Scanning Calorimetry Testing

Stress Engineering Services provides Differential Scanning Calorimetry (DSC) for thermal analysis of polymers, elastomers, polymer based composites and liquids to support a variety of industrial market sectors and functions.

DSC can be used to determine the effect of thermal aging, chemical aging and medical sterilization. It is also a valuable compositional analysis tool, making it useful for reverse engineering. Material samples can be as small as 0.5 mg. Our expert engineering staff conducts analysis using both standardized and customized methodology. The common test methods performed are as follows.

Standard Tests:

ASTM D7426, E1356:  Glass Transition Temperature (Tg)

ASTM D3895, E1858:  Oxidative Induction Time via DSC

ASTM D3418: Transition Temperatures of Polymers

ASTM D2070:  Kinetic Parameters via Isothermal DSC

ASTM E928:  Determination of Purity via DSC

ASTM E1269: Determination of Specific Heat Capacity

ASTM E793:  Enthalpies of Fusion/Crystallization

ISO 11357/22768:  Melting and Crystallization/Tg Analysis
