中文名称：炼铝用碳素材料.电极沥青.用氧弹法测定硫含量

英文名称：Carbonaceous materials for the production of aluminium — Pitch for electrodes — Determination of sulfur content by the bomb method

发布日期：1988-12

标准范围

样品在装有氧气的炸弹中加压燃烧氧化。硫以硫酸钡的形式通过重量法测定炸弹清洗液中的硫。该方法适用于煤沥青和石油沥青，前提是其含硫量至少为0.1%（m/m）。

A sample is oxidized by combustion in a bomb containing oxygen under pressure. The sulphur is gravimetrically determined in the bomb washings in the form of barium sulfate. The method is applicable to pitches of both coal ta and petroleum origin, provided that they contain at least 0,1 % (m/m) sulfur.
