scope:

This document specifies seven inductively coupled plasma emission spectrometry methods (A to G) for the determination of alloying elements and impurities in copper and copper alloys in the form of unwrought, wrought and cast products. These methods are applicable to the elements listed in Tables 1 to 7 within the composition ranges shown: Table 1 - Coppers Table 2 - Copper-zinc alloys Table 3 - Copper-tin alloys Table 4 - Copper-aluminium alloys Table 5 - Copper-beryllium alloys Table 6 - Copper-nickel alloys Table 7 - Copper-tin-lead alloys NOTE 1 The ranges specified for each method can be extended or adapted, for the determination of lower mass frac-tions. NOTE 2 Other elements may be included. However such elements and their mass fractions should be carefully checked, taking into account interference, sensitivity, resolution and linearity criteria for each instrument and each wave-length.
