1.1 本试验方法为确定 典型的 -在存在稳定剂和杂质的情况下，未经处理或回收的溴化丙酯（重量百分比） 典型的 -丙基溴( n PB）。应用范围为50 wt%至100 wt%。 1.2 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 3.1 本试验方法提供了以下重量百分比的分析: 典型的 -未净化、配制或回收的丙基溴浓度 典型的 -丙基溴:与 典型的 -丙基溴或 典型的 -庚烷（内标物）可能会干扰本试验方法。

1.1 This test method provides a basis for the determination of the normal -propyl bromide (weight %) in the presence of stabilizers and impurities, in virgin or reclaimed normal -propyl bromide ( n PB). The application range is from 50 wt % to 100 wt %. 1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 3.1 This test method provides an analysis in weight percent of the normal -propyl bromide concentration of virgin, formulated, or reclaimed normal -propyl bromide: compounds that co-elute with normal -propyl bromide or normal -heptane (internal standard) may interfere with this test method.
