JIS G 1258-1:2014

This Japanese Industrial Standard specifies ICP atomic emission spectrometric method using decomposition in acids and fusion with potassium disulfate to determine the content rate of 16 components specified in Table 1 (silicon, manganese, phosphorous, nickel, chromium, molybdenum, copper, vanadium, cobalt, titanium, aluminium, calcium, magnesium, arsenic, zirconium and zinc) in steel. This method is not applicable to steels in which the iron content (mass fraction) is less than 92 %, steels which contain one or more components of content rate over the maximum limit of determination specified in Table 1, or steels which contain components not specified in Table 1 (e.g. carbon) by mass fraction 1.0 % or more (for tungsten, mass fraction 0.1 % or more).
