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.

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 (nPB). The application range is from 50 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.
