硫化橡胶 - 通过气相色谱（Gc）和高效液相色谱（Hplc）测定游离硫

[中文适用范围]： 本文件规定了测定橡胶硫化过程中未消耗的无机游离硫（Sx）的色谱法。该方法主要用于比较不同样品中的游离硫含量。注 1 本文件中使用“游离硫”代替“无机游离硫”。注 2 含硫残留硫化剂不在本测量范围内。 [外文原描述]： This document specifies chromatographic methods for the determination of the inorganic free sulfur (Sx) not consumed during the vulcanization of the rubber. This method is used primarily to compare the free sulfur content in different samples. NOTE 1 In this document, "free sulfur" is used instead of "inorganic free sulfur". NOTE 2 The residual curing agent containing sulfur is not concerned by this measure.
