ISO 16962:2017规定了辉光放电光发射光谱法,用于测定由锌和/或铝基材料组成的金属表面涂层的厚度、单位面积质量和化学成分。所考虑的合金元素为镍、铁、硅、铅和锑。
本方法适用于质量分数在0.01%至100%之间的锌含量;铝含量在0.01质量%和100质量%之间;镍含量在0.01质量%和20质量%之间;铁含量在0.01质量%和20质量%之间;硅含量在0.01质量%和15质量%之间;
镁含量在0.01质量%和20质量%之间;铅含量在0005质量%和2质量%之间,锑含量在0005质量%和2质量%之间。
注:由于环境和健康风险,目前避免使用铅和锑,但本文件也适用于包括这些元素的旧产品。
ISO 16962:2017 specifies a glow-discharge optical-emission spectrometric method for the determination of the thickness, mass per unit area and chemical composition of metallic surface coatings consisting of zinc- and/or aluminium-based materials. The alloying elements considered are nickel, iron, silicon, lead and antimony.
This method is applicable to zinc contents between 0,01 mass % and 100 mass %; aluminium contents between 0,01 mass % and 100 mass %; nickel contents between 0,01 mass % and 20 mass %; iron contents between 0,01 mass % and 20 mass %; silicon contents between 0,01 mass % and 15 mass %; magnesium contents between 0,01 mass% and 20 mass%; lead contents between 0,005 mass % and 2 mass %, antimony contents between 0,005 mass % and 2 mass %.
NOTE Due to environmental and health risks, lead and antimony are avoided nowadays, but this document is also applicable to older products including these elements.
