Abstract
The ICTAC Committee on Standardisation has formed a Task Group to inve stigate the suitability of the ICTAC Certified Reference Materials for DTA, covering the temperature range 450-degrees-1100-degrees-C, for a ccurate temperature calibration purposes and to evaluate their potenti al as enthalpy calibrants for DTA and DSC equipment. This paper report s the results of preliminary round-robin studies on barium carbonate a nd strontium carbonate, using a dual-point calibration method based on the melting points of aluminium and gold. In addition the fusion of I CTAC potassium sulphate has been investigated as a possible calibratio n transition.
