本文件规定了测定镍合金中钛含量的分子吸收分光光度法。 该方法适用于0.3%（质量分数）至5.0%（质量分数）之间的钛含量。 如果合金中存在钼，则会导致报告的钛值出现高偏差，每1,0%钼的钛含量为0001%。 注1:有证据表明，当钛含量降至0.05%（质量分数）时，可以扩展该方法。 注2:通用方法中的修改允许测定含钨和/或钽合金中的钛。

This document specifies a molecular absorption spectrophotometric method for the determination of titanium content in nickel alloys. The method is applicable to titanium contents between 0,3 % (mass fraction) and 5,0 % (mass fraction). Molybdenum, if present in the alloy, can cause a high bias in the reported titanium value to the extent of 0,001 % Ti for every 1,0 % Mo. NOTE 1 Evidence exists that extension of this method is possible for titanium contents down to 0,05 % (mass fraction). NOTE 2 Modifications in the general method allow the determination of titanium in alloys containing tungsten and/or tantalum.
