Scope

This document specifies an inductively coupled plasma optical emission spectrometry routine
method for the analysis of unalloyed and low alloyed steels, with an iron content of at least 95 %.
This method is applicable to the elements listed in Table 1 within the ranges shown.
Table 1 - Application ranges
(...)
In all cases, the ranges specified can be extended or adapted (after validation) for the
determination of other mass fractions, provided that the iron content in the samples under
concern is above 95 %.
Other elements may be included. However such elements and their mass fractions are to be
carefully checked, taking into account the possible interferences, the sensitivity, the resolution
and the linearity criteria of each instrument and each wavelength.
Depending also on the sensitivity of each instrument, suitable dilutions of the calibration and the
test sample solutions may be necessary.
Moreover, even if the method described is "multi elemental", it is not absolutely necessary to
carry out the determination of all the elements of its scope simultaneously: the measurement
conditions have to be optimised by each laboratory, depending on the performances of each
apparatus available.
NOTE 1 The accuracy of the method is unsatisfactory for phosphorus contents from 0,05 to 0,1 %.
NOTE 2 The trueness of the method couldn't be checked for vanadium contents below 0,05 %.
NOTE 3 The precision of the method is unsatisfactory for aluminium (total) contents below 0,02 %.
