Standards, calibration, and guidelines in microcalorimetry. Part 2. Calibration standards for differential scanning calorimetry* (IUPAC Technical Report)

TLDR

Differential scanning calorimeters (DSCs) are widely used for temperature, heat capacity, and enthalpy measurements from subambient to high temperatures. The present recommendations describe procedures and reference materials for calibrating DSCs. The recommendations detail instrument response calibration, measurement‑uncertainty estimation, temperature, enthalpy, and heat‑flow rate calibration procedures, and list reference materials with their relevant properties. Calibration on cooling has also been considered.

Abstract

Abstract Differential scanning calorimeters (DSCs) are widely used for temperature, heat capacity, and enthalpy measurements in the range from subambient to high temperatures. The present recommendations describe procedures and reference materials (RMs) for the calibration of DSCs. The recommendations focus on the calibration of the response of the instrument and on the estimation of the measurement uncertainty. The procedures for temperature, enthalpy, and heat-flow rate calibration are given in detail. Calibration on cooling has also been considered. Recommended RMs are listed, and the relevant properties of these materials are discussed.
