The 19th Sectional Committee (Steel) of the Japan Society for the Promotion of Scientific Research was formed in 1935 by Professor Kuniichi Tawara, and the Analysis Sub-Committee of it has been actively engaged in the study of methods of chemical analysis of iron and steel, endevouring to standardizing them. In recent years a great amount of research work on the methods for the determination of gases and non-metallic inclusions in iron and steel, and on the very rapid analytical methods for use on the furnace stage have been undertaken and published in the papers of. the Sub-Committee and the following books: K. Tawara, Tekko Kagaku Bunseki Zensho (Chemical Analysis of Iron and Steel),1951; Japan Society for the Promotion of Scientific Research, Rapid Methods of Chemical Analysis of Iron and Steel,4 th ed.,1955.
Recent development in the following methods is also written: classical methods of chemical analysis, rationalization of analysis, standard methods and specification methods, electrochemical methods, spectrographic methods, metallurgical analysis (metallkundliche Analyse), gas analysis, application of radio-isotopes, and application of statistical methods.
