标准摘要
[中文适用范围]: 本标准规定了测定钢和铁中铬含量的电位滴定法。 该方法适用于铬含量在 1% (mlm) 至 35% (mlm) 之间。 对于铬含量高于 10 % (m/m) 的钢和铁,钒含量应低于 1 % (m/m);对于铬含量低于 10 % (mlm) 的钢和铁,钒含量应低于 0.2 % (m/m) )。 [外文原描述]: This International Standard specifies a potentiometric titration method for the determination of chromium content in steel and iron. The method is applicable to chromium contents between 1 % ( m / m ) and 35 % ( m / m ). Vanadium contents in steel and iron should be less than 1 % ( m / m ) for chromium contents higher than 10 % ( m / m ) and less than 0,2 % (m/m) for chromium contents less than 10 % ( m / m ).
