标准摘要
[中文适用范围]： 样品在压力下含有氧气的炸弹中燃烧而被氧化。 硫在弹洗液中以硫酸钡的形式通过重量分析测定。 该方法适用于煤沥青和石油来源的沥青，只要它们含有至少 0.1% (m/m) 的硫。 [外文原描述]： 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.
