中文名称：硫化橡胶 气相色谱（GC）和高效液相色谱（HPLC）测定游离硫
英文名称：Vulcanized rubber — Determination of free sulfur by gas chromatography (GC) and high performance liquid chromatography (HPLC)
发布日期：2019-07
标准范围
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.
