1 Subject Content and Application Scope This standard specifies the determination of bromine index in petroleum hydrocarbons by electrometric titration. This standard is applicable to the determination of hydrocarbon mixtures having a distillation end point under 288℃ and free from light fractions of a boiling point lower than -10℃, and hydrocarbons with bromine indexes in the range from 100 to 1000, which include such petroleum distillates as straight-run and hydrocracked naphtha, reformer feed, kerosene and aviation turbine fuel, etc. 2 Normative References GB 1884 Crude Petroleum and Liquid Petroleum Products - Laboratory Determination of Density - Hydrometer Method GB 1885 Petroleum Measurement Tables GB 6682 Water for Laboratory Use - Specification 3 Definition and Significance
