In order to ensure chromium The iron detection standards are convenient and accurate. For the analysis methods of different elements of ferrochromium, a national standard system supporting the detection of ferrochromium has been established. GB/T 5687 (all parts) is the basic standard for ferrochrome testing in my country, and it is planned to consist of the following thirteen parts. But some parts have been abolished, Need to pay attention to during use. ---GB/T 5687.1-1985 "Methods for chemical analysis of ferrochromium". The purpose is to measure chromium The chromium content in iron uses the ammonium persulfate oxidation volumetric method. This part has been abolished. ---GB/T 5687.2-2007 "Determination of ferrochromium, silicon-chromium alloys and chromium-nitride silicon content-Perchloric acid dehydration gravimetric method". Item The purpose is to measure the silicon content in ferrochrome, silicon-chromium alloy and ferrochrome nitride, using the perchloric acid dehydration gravimetric method. ---GB/T 5687.3-1985 "Methods for chemical analysis of ferrochromium, the molybdenum blue photometric method for the determination of phosphorus content". The purpose is to measure the phosphorus in ferrochrome The content is based on the molybdenum blue light method. This part has been abolished. ---GB/T 5687.4-2016 "Determination of Nitrogen Content of Ferrochromium Nitride and High Nitrogen Chromium Ferro-Nitrogen Distillation-Neutralization Titration Method". The purpose is to test To measure the nitrogen content in ferrochrome nitride and high-nitrogen ferrochrome, use the distillation-neutralization titration method. ---GB/T 5687.5-1988 "Methods for Chemical Analysis of Ferrochromium.
