NOMENCLATURE IN THERMAL-ANALYSIS .4.

The recommendations in the earlier reports of the Nomenclature Committee of the International Confederation for Thermal Analysis (ICTA)1-3 and its Sub-Committees4-7 have been well received and have been accepted by such international and national bodies as IUPAC8, ISO9, ASTM10 and AFNOR11. An integrated version of the second and third reports2,3 is currently being considered for adoption by IUPAC12. The unofficial and accurate translations that have appeared in several other languages3 are welcomed. A Working Group on Symbols has now been established under the Chairmanship of Dr.J. H. Sharp, U.K., and a Sub-Committee on nomenclature in the Chinese language, convened by Dr. D. T. Y. Chen, Hong Kong, has issued its firs publication.13. It has become evident since the first report1 was published that the definition of thermal analysis given therein is not entirely satisfactory; moreover, over the years several new techniques have emerged or minor techniques have assumed increasing importance. The Committee, having considered both these factors, presented the following report to the Fifth International Conference on Thermal Analysis, Kyoto, Japan, in August 1977, where it was accepted at the Business Session. Council of ICTA have therefore directed that it be published as a definitive document of ICTA with the request that the recommendations herein be adhered to in all publications in the English language. © 1979.
