ISO 3815-2:2005规定了根据ISO 301和ISO 752通过电感耦合光发射光谱法测定锌和锌合金化学成分的分析方法。 ISO 3815-2:2005包括锌和锌合金试验溶液和校准溶液的制备规定。 每种方法规定的范围可以扩展和/或适用于低浓度的测定。 ISO 3815-2:2005可适用于其他元素（如镍、铬和钛）。然而，这些结果需要仔细检查，考虑到每个仪器和每个波长的干扰、灵敏度、分辨率和线性标准。

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.
