This standard specifies the determination method of calcium content in mg and magnesium alloys, which is applicable from 0.0020% to 0.050%. The method uses muriatic acid to dissolve the sample, and in the presence of chlorinated mace, the calcium content is determined at a wavelength of 422.7 nm by air-acetylene flame. The standard details the configuration of reagents, instrument requirements and operation steps, and is suitable for the detection of calcium content in magnesium alloy materials in the metallurgical industry.
