[Current]Lead alloys, Part 1: Determination of antimony content — Flame atomic absorption spectrometric method
Sets out a flame atomic absorption spectrometric method for the determination of antimony in lead alloys in the concentration range 0.1 to 3.5 percent antimony. The method is suitable in the presence of up to 2.5 percent tin and 2.5 percent arsenic. This Standard is a new edition of AS 1671.1-1974 without technical alterations.
