本文件规定了在使用管式炉燃烧法或氧气燃烧瓶法制备样品溶液后，通过离子色谱法测定生橡胶和未硫化或硫化橡胶化合物中总硫含量的方法。 管式炉燃烧法适用于硫含量小于0.1%的橡胶，因为氧燃烧瓶法可能无法给出足够准确的结果。 氧气燃烧瓶法不适用于含有形成不溶性金属硫酸盐的金属盐的橡胶，如硫酸钡（CAS？7727？43？7）。

This document specifies a method for the determination of the total sulfur content of raw rubber and unvulcanized or vulcanized rubber compounds by ion chromatography following the preparation of a sample solution using either a tubular furnace combustion or an oxygen combustion flask method. The tubular furnace combustion method is applicable for rubbers with sulfur content less than 0,1？% as it is possible that the oxygen combustion flask method will not give sufficiently accurate results. The oxygen combustion flask method is not applicable to rubbers containing a metal salt that forms an insoluble metal sulfate, such as barium sulfate (CAS？7727？43？7).
