1 Scope
This International Standard specifies a method for the determination of the bromine number of the following materials:
a) petroleum distillates that are substantially free of material lighter than 2-methylpropane, and that have 90 %( V/V ) (i.e. volume fraction 90 %) distillation recovery temperatures under 327 °C. The method is generally applicable to gasolines (including leaded, unleaded and oxygenated fuels), kerosines and distillates in the gas oil range that fall within the following limits:
90 %( V/V ) recovery distillation temperature (ISO 3405)
Bromine number , max. (see note 1)
