中文名称:橡胶.总硫含量的测定.第1部分:氧气燃烧瓶法
英文名称:Rubber — Determination of total sulfur content — Part 1: Oxygen combustion flask method
发布日期:1992-07
标准范围
适用于NR、CR、SBR、BR、IR、IIR、EPDM、NBR和硬质橡胶(见ISO 1629)。该方法的原理是在有过氧化氢存在的氧气环境中通过点火进行氧化,将硫转化为硫酸,并通过高氯酸钡滴定测定硫酸盐。本方法适用于测定橡胶或橡胶制品中的所有硫,硫酸钡中的硫除外。
Is applicable to NR, CR, SBR, BR, IR, IIR, EPDM, NBR, and ebonite (see ISO 1629). The principle of the method is oxidation by ignition in an atmosphere of oxygen in the presence of hydrogen peroxide, conversion of sulfur to sulfuric acid, and determination of the sulfate by titration with barium perchlorate. The method is applicable for the determination of all the sulfur present in a rubber or rubber product, except that contained in barium sulfate.
