标准摘要
[中文适用范围]： 本文件规定了用原子吸收分光光度法测定橡胶中铜含量的方法。该方法适用于铜含量高于1 ppm的生胶及橡胶制品；若铜含量低于此限值，可通过调整试样质量或所用溶液浓度（或两者同时调整）进行测定。采用标准加入法可进一步降低检测下限。 [外文原描述]： This document specifies an atomic absorption spectrometric method for the determination of the copper content of rubbers. The method is applicable to raw rubber and rubber products having copper contents above 1 ppm. Copper contents below this limit can be determined, provided that suitable adjustments are made to either the mass of the test portion or to the concentrations of the solutions used, or both. The use of the standard additions method can lower the bottom limit of detection.
