《GB/T 6150.12-2008钨精矿化学分析方法二氧化硅量的测定硅钼蓝分光光度法和重量法》由TC243（全国有色金属标准化技术委员会）归口，TC243SC3（全国有色金属标准化技术委员会稀有金属分会）执行，主管部门为中国有色金属工业协会。
ＧＢ／Ｔ６１５０《钨精矿化学分析方法》分为１７部分,本部分为ＧＢ／Ｔ６１５０的第１２部分。本方法规定了钨精矿中二氧化硅含量的测定方法。本部分代替ＧＢ／Ｔ６１５０．１４―１９８５《钨精矿化学分析方法　钼蓝光度法测定二氧化硅量》.本方法适用于钨精矿中二氧化硅含量的测定。测定范围（质量分数）：０．５０％～３．００％。本部分与ＧＢ／Ｔ６１５０．１４―１９８５相比主要变化如下：
―――采用两种方法测定钨精矿中的二氧化硅量；
―――方法１测定范围由０．５０％～１０．００％修订为０．５０％～３．００％；增加了重复性与质量保证和控制条款；
―――方法２为新增方法，采用重量法测定高含量二氧化硅量。
