Bibliography
This document specifies a flame atomic absorption spectrometric method after extraction for the determination of tin in zinc and zinc alloys. It is applicable to the products specified in EN 988, EN 1179, EN 1774 and EN 12844.It is suitable for the determination of tin contents (mass fractions) between 0,000 5 % and 0,005 %.
