标准范围

适用于表1规定范围内的精炼、锻造和铸造镍。该方法适用于所列任何一种或多种元素的独立测定。如果制备了特殊的标准溶液，铁的较低水平可延长至低于00025%（m/m）。对该方法稍加修改，即可将钴和铜的测定上限提高到2%（m/m）。有关潜在干扰，请参见第10条。

Applies to refined, wrought and cast nickel within the ranges specified in table 1. The method is applicable to the independent determination of any one or more of the elements listed. The lower level for iron can be extended to less than 0,0025 % (m/m) provided a special standard solution is prepared. The upper limit for the determination of cobalt and copper can be raised to 2 % (m/m) by a minor modification to the method. For potential interferences, see clause 10.
