Thermal events in the sample thus appear as deviations from the baseline, in either an endothermic or exothermic direction, depending upon whether more or less energy is supplied to the sample compared with the reference material. The operational temperature range of DSC is less than that of DTA—being typically subambient to 750°C. Temperature and energy calibration of DSC instruments is achieved using the ICTAC certified reference materials. ...

Thermal analysis systems require calibration prior to routine use. In TGA, calibration for mass is carried out by calibrating the microbalance using a set of standard weights, as for any balance system. Temperature calibration is effected by measuring the Curie point temperatures of a suite of International Confederation for Thermal Analysis and Calorimetry (ICTAC) Certified Reference Materials, which have well-defined Curie points. ... 

The possibility of performing sample controlled thermomagnetometry is illustrated by an SCTM experiment on ICTAC nickel, with a permanent magnet placed above the thermobalance furnace (Fig. 9).

According to the definition presented by the International Confederation of Thermal Analysis and Calorimetry (ICTAC), thermal analysis is a group of techniques in which a physical property of a substance is measured while the substance is subjected to a controlled temperature programme . Table 7.3 summarizes the most important techniques that are briefly discussed below. 

Differential thermal analysis DTA is defined as a technique in which the temperature difference between a substance and a reference material is measured as function of temperature, while the substance and reference are subjected to a controlled temperature (ICTAC definition [59]).

The nomenclature of thermal analysis continues to be a controversial and incompletely resolved topic. The system proposed by the ICTAC Nomenclature Committee chaired by W. Hemminger and described in detail by Hemminger and Sarge in Volume 1 [Vol 1, p 1-31] has since been reconsidered by a further Committee and die latest recommendations, which have been approved by the Council of ICTAC and by ASTM, are presented by Rouquerol et al. in Chapter 2 of this Volume. The current Committee has followed the advice of the late Robert Mackenzie in that ... 

The present official nomenclature for Thermal Analysis is thus contained in the Report of the ICTAC Nomenclature Committee, which is reproduced (with the permission of ICTAC) in Section 2. In Section 3 a number of extra comments are provided in order to justify, explain or complement the material in Section 2. 

The scope of this document is to provide scientists working in the field of thermal analysis with a consistent definitions of terms that are commonly used within the field to allow precise communication and understanding. Since the scope of ICTAC also covers calorimetry, a further document dealing with this... 

The definition proposed in 1991 in the ICTAC booklet For Better Thermal Analysis and Calorimetry [10] was as follows ... 

This definition is more complicated than the first one and, in reality, although proposed to the ICTAC membership, was never officially endorsed by the ICTAC Council. It still does not embrace the case of sample-controlled thermal analysis, although SCTA is referred to in that 1991 booklet, in the form of controlled rate thermal analysis (CRTA). 

Then came the definition endorsed in 2006 by the ICTAC Council ... 

Reference materials for combustion calorimetry have been recommended by the lUPAC Commission Physicochemical Measurements and Standards [130-132] and by the ICTAC Thermochemistry Working Group [133]. They are classified as primary, secondary and tertiary reference materials and when their properties are certified by a national or international organization, agency or laboratory authorized they are called certified reference materials . For combustion calorimetry, the recommended reference materials must be selected according to the atoms in the molecule and its physical state [133] benzoic acid (C,H,0, cr, primary), succinic acid (C,H,0, cr, secondary), hippuric acid (C,H,0,N, cr, tertiary), acetanilide (C,H,0,N, cr, secondary), nicotinic acid (C,H,0,N, cr, tertiary), 1,2,4-triazole (C,H,0,N, cr, secondary)[134], urea (C,H,0,N, cr, tertiary), thiantrene (C,H,0,S, cr, secodary), 4-fluorobenzoic acid (C,H,0,F, cr, secondary), pentafluorobenzoic acid (C,H,0,F1, cr, tertiary), 4-chorobenzoic acid (C,H,0,C1, cr, secondary), 4-bromobenzoic acid (C,H,0,Br, cr, tertiary), 4-iodobenzoic acid (C,H,0,I, cr, tertiary), triphenylphosphine oxide...
