ASTM D1492 – Standard Test Method for Bromine Index of Aromatic Hydrocarbons by Coulometric Titration
Description:
Significance and Use
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.
Scope
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.
