本欧洲标准规定了用于测定锌和锌合金中的铅，铜和镉的火焰原子吸收光谱法。它适用于EN 988，EN 1179，EN 1774，EN 12844和prEN 13283中规定的产品。 适用于测定镉含量（质量分数）在0.0005％至0.3％之间的铅含量（质量分数）在0.0005％和2.5％之间，铜质量分数在0.0005％和4％之间

This European Standard specifies a flame atomic absorption spectrometry method for the determination of lead, copper and cadmium in zinc and zinc alloys. It is applicable to the products specified in EN 988, EN 1179, EN 1774, EN 12844 and prEN 13283. It is suitable for the determination of lead contents (mass fractions) between 0,000 5 % and 2,5 %, cadmium contents (mass fractions) between 0,000 5 % and 0,3 %, and copper mass fractions between 0,000 5 % and 4 %.
