标准摘要
[中文适用范围]： 本文件规定了一种原子吸收分光光度法，用于测定橡胶中的锰含量。该方法适用于锰含量高于0.5 ppm的橡胶原料及橡胶制品；对于锰含量低于此限值的样品，可通过适当调整试样质量、所用溶液的浓度或两者兼施的方式予以测定；采用标准加入法可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 manganese content of rubbers. The method is applicable to raw rubber and rubber products having manganese content above 0,5 ppm. Manganese contents below this limit can be determined, provided that suitable adjustments are made either to 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.
