本文件规定了测定橡胶中锌含量的原子吸收光谱法。 该方法适用于锌含量至少为0.05%（质量分数）的生橡胶和橡胶制品。如果对试验部分的质量和/或所用溶液的浓度进行适当调整，则可确定低于该限值的锌含量。使用标准加入法可能会降低检测下限。

This document specifies an atomic absorption spectrometric method for the determination of the zinc content of rubbers. The method is applicable to raw rubber and rubber products having zinc contents at a minimum of 0,05 % (mass fraction). Zinc contents below this limit can be determined, provided that suitable adjustments are made to the mass of the test portion and/or to the concentrations of the solutions used. The use of the standard additions method might lower the bottom limit of detection.
