This section GB/T 13748 Part 10. The object is to have a standard adoption of Part 1, Part 4, Section 7, Section 8, Section 9, Section 10, Section 12, Part 14, Part 159 sections revised. This section drafted in accordance with GB/T 1.1-2009 given rules. This Part replaces GB/T 13748.10-2005 "Determination of magnesium and magnesium alloys - Analysis of silicon content - Molybdenum blue spectrophotometric law". This section compared with the GB/T 13748.10-2005, the main technical changes are as follows. --- To increase the "lab report" requirement; --- Remove the "quality assurance and control" requirements. This section uses redrafted reference method ISO 1975. 1973 "Magnesium and magnesium alloys - Determination of silicon molybdenum blue photometric method", and ISO 1975. 1973 non-equivalent. The non-ferrous metal part by the National Standardization Technical Committee (SAC/TC243) centralized. This section is responsible for drafting units. Aluminum Corporation of China Zhengzhou Research Institute, China Nonferrous Metals Industry Quality Standards and Metrology Institute The study. This section is drafted.
