In order to establish a standard analytical method for the determination of trace amounts of tin and lead in magnesium and its alloys, which could be found in neither JIS nor ISO standards, an interlaboratory testing with inductively coupled plasma atomic emission spectrometry (ICP-AES) has been put into practice. Simple dissolution with nitric and hydrochloric acids and sample nebulization procedures were finally concluded to be suitable for standardization. The analytical methods, proposed in this study have been provided as newly established JIS standards.
