Full title and description
ASTM E967-18 — Standard Test Method for Temperature Calibration of Differential Scanning Calorimeters (DSC) and Differential Thermal Analyzers (DTA). This method defines procedures and acceptance practices for calibrating the temperature axis of DSC and DTA instruments so that measured transition temperatures can be reported with known traceability and uncertainty.
Abstract
ASTM E967-18 provides a concise, practical procedure to calibrate the temperature measurement of differential scanning calorimeters and differential thermal analyzers. The standard covers selection and use of calibration materials, apparatus requirements, controlled heating through thermal transitions, data collection and interpretation (peak identification), and documentation needed to establish temperature accuracy and traceability over the stated temperature range.

Scope
This test method describes temperature calibration procedures for differential thermal analyzers and differential scanning calorimeters across a wide temperature range (nominally −40 °C to +2000 °C). It specifies apparatus types, controlled heating through known thermal transitions, the use of reference calibration materials, atmosphere control where required, and techniques for recording and determining transition temperatures for the purpose of establishing the instrument temperature axis.
Key topics and requirements
- Apparatus requirements: DSC or DTA configurations, furnace and temperature sensors capable of the applicable range and controlled heating rates.
- Selection and use of calibration materials with well-characterized transition (melting, phase change) temperatures.
- Calibration procedure: heating rates, atmosphere control, sample and reference preparation, and repeat measurements.
- Data collection and interpretation: recording heat flow or temperature difference, identification of endothermic/exothermic peaks, and assignment of transition temperatures.
- Traceability and uncertainty: documentation of reference material values, measurement uncertainty assessment, and traceability to recognized standards.
- Reporting and acceptance criteria: how to present calibration results, corrections to the temperature axis, and criteria for accept/reject.
- Safety and applicability notes: user responsibilities for laboratory safety and environmental considerations.
Typical use and users
Used by analytical laboratories, instrument manufacturers and service engineers, quality assurance/quality control departments, and research groups that perform thermal analysis. Typical industries include polymers and plastics, pharmaceuticals, chemicals, materials research, petrochemicals, and academia. The standard is applied when instruments require verification, periodic calibration, method validation, or when reporting absolute transition temperatures for regulated testing.
Related standards
Closely associated documents include ISO 11357‑1 (DSC general principles), ASTM E473 (terminology relating to thermal analysis and rheology), ASTM E1142 (terminology relating to thermophysical properties), and ASTM practices for heat‑flow calibration such as the withdrawn/related practice E968 (heat flow calibration) and other thermal analysis methods (for example ASTM E793, E794, E928 series). Note: a formal ASTM work item (WK93743) to revise E967-18 and to merge with the withdrawn E968 was initiated on February 5, 2025.

FAQ
Q: What is this standard?
A: ASTM E967-18 is a test method that defines how to calibrate the temperature axis of differential scanning calorimeters and differential thermal analyzers so transition temperatures can be reported accurately and with traceability.
Q: What does it cover?
A: It covers apparatus requirements, selection and use of calibration materials, controlled heating through thermal transitions, data recording and peak identification, assessment of uncertainty and traceability, and reporting of calibration results over the nominal range −40 °C to +2000 °C.
Q: Who typically uses it?
A: Instrument manufacturers and service engineers, analytical and materials testing laboratories, QA/QC teams in pharmaceuticals, polymers, chemicals and petrochemical industries, and academic researchers using DSC/DTA.
Q: Is it current or superseded?
A: As of February 21, 2026, E967-18 (approved March 15, 2018) is the current published edition. A revision work item (WK93743) was opened on February 5, 2025 to update the practice and to merge material from a withdrawn related practice; that work item indicates a revision is in progress but does not by itself indicate the 2018 edition has been superseded.
Q: Is it part of a series?
A: Yes. E967 is part of a set of ASTM standards and practices for thermal analysis and calorimetry administered by Committee E37 (Subcommittee E37.01). It is intended to be used alongside terminology standards (ASTM E473, E1142) and complementary test methods/practices for heat‑flow calibration and other thermal measurements.
Q: What are the key keywords?
A: temperature calibration, DSC, DTA, thermal analysis, calibration materials, transition temperature, heat flow, traceability, uncertainty.
