1.1 This test method covers the determination of Bromine Index in aromatic hydrocarbons, their derivatives, and related chemicals.

1.2 This test method is applicable to samples with Bromine Index concentrations to 100 Bromine Index. The limit of detection (LOD) is for 1.5 Bromine Index and the limit of quantitation (LOQ) is 4.9 Bromine Index.

Note 1: LOD and LOQ were calculated using data from the D16 PTP program. This estimate of LOD includes within-lab variability.

1.3 The following applies for the purposes of determining the conformance of the test results using this test method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 8.

1.6 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.


5.1 This test method is useful as an internal quality control tool, and for use in development or research work on industrial aromatic hydrocarbons and related materials. This test method gives a broad indication of olefinic content. It will not differentiate between the types of aliphatic unsaturation.
