ISO 3815-2:2005 specifies analytical methods for determining the chemical composition of zinc and zinc alloys in accordance with ISO 301 and ISO 752 by inductively coupled optical emission spectrometry.

ISO 3815-2:2005 includes provisions for preparation of test solutions and calibration solutions for zinc and zinc alloys.

The ranges specified for each method can be extended and/or adapted for determinations of low concentrations.

ISO 3815-2:2005 can be applied to other elements (e.g. Ni, Cr and Ti). However, such results will need to be carefully checked by taking into account the interferences, the sensivity, the resolution and the linearity criteria for each instrument and each wavelength.
