DESCRIPTION
BS EN 12441-3:2002
This standard BS EN 12441-3:2002 Zinc and zinc alloys. Chemical analysis is classified in these ICS categories:
77.120.60 Lead, zinc, tin and their alloys
77.040.30 Chemical analysis of metals
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 %.
