Description / Abstract:

This Standard specifies decomposition with phosphoric and sulfuric acids among determinations of tungsten in steel using ICP atomic emission spectrometric method. This method is applicable to determination of tungsten content rate (mass fraction) of 10.0 % or over to and including 20.0 % in steel. However, it is not applicable to steels containing one or more coexisting components with content rate [mass fraction (%)] over the upper limits specified
