标准摘要
[中文适用范围]： 本标准规定了测定橡胶中锌含量的原子吸收光谱法。该方法的适用范围为：锌含量不低于0.05%（质量分数）的生胶及橡胶制品；若对试样质量及/或所用溶液浓度进行适当调整，亦可测定低于此限值的锌含量。采用标准加入法有助于进一步降低方法的检出限。 [外文原描述]： 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.
