Overview
ASTM E 967 Temperature Calibration Testing: The standardized testing procedure to calibrate the temperature scale of differential scanning calorimeters and differential thermal analyzers using certified reference materials to ensure traceable accuracy in the range of temperatures that can be achieved in a defined melting point calibration procedure. The reference materials to be used in the calibration process, as well as the procedure for correcting the accuracy of DSCs and DTAs, are defined in the ASTM E 967 testing procedure to ensure accurate data can be obtained in DSC/DTA testing.
Scope, Applications, and Benefits
Scope
ASTM E 967 standards are used to calibrate the temperature scale of DSC and DTA instruments by determining the onset melting points of certified reference standards within the equipment’s operating range. The onset melting points are compared to the certified reference standards to establish the temperature correction factors and accuracy of the equipment temperature scale.
ASTM E 967 temperature calibration testing evaluates:
- Temperature scale accuracy of DSC and DTA instruments across the operating temperature range
- Onset melting temperature measurement of certified reference materials per ASTM E 967
- Temperature correction factor determination for DSC and DTA instrument calibration
- Instrument temperature linearity and accuracy across defined calibration temperature points
- Compliance with ASTM E 967 temperature accuracy acceptance criteria for thermal analysis instruments
Applications
- DSC and DTA instrument temperature calibration for polymer thermal analysis programs
- Pharmaceutical DSC temperature calibration for melting point and purity assessment
- Materials research DSC and DTA temperature accuracy verification programs
- Production laboratory thermal analysis instrument temperature calibration programs
- Calibration laboratories requiring ASTM E 967 DSC and DTA temperature calibration data
Benefits
- Provides reliable DSC and DTA temperature calibration data for thermal analysis accuracy assurance
- Supports thermal analysis instrument compliance and measurement traceability requirements
- Identifies temperature accuracy deficiencies in DSC and DTA instruments before analysis programs
- Delivers traceable temperature calibration records for laboratory and regulatory submissions
- Reduces thermal analysis measurement risk by verifying instrument temperature accuracy early in calibration
