标准摘要
[中文适用范围]: 本标准规定了用二甲基乙二肟分光光度法测定钢中镍的方法。 该方法适用于0.10%和2.0%范围内镍质量分数的测定。 钴、铜和锰会引起干扰(见 7.3.2)。 [外文原描述]: ISO 4939:2016 specifies a spectrophotometric method for the determination of nickel in steel using dimethylglyoxime. The method is applicable to the determination of nickel mass fractions in the range of 0,10 % and 2,0 %. Cobalt, copper and manganese can cause interferences (see 7.3.2).
英文名称Steel — Determination of nickel — Dimethylglyoxime spectrophotometric method
