1.1 This International Standard specifies a method for determining the boiling range of liquids that boil between 30 and 300 “C at normal pressure, and that are chemically stable and do not torrode the apparatus during the disti I lation. 1.2 The method is applicable to organic liquids such as hydrocarbons, esters, alcohols, ketones, ethers and similar products. NOTE - The mthod differs from that described in ISO/R 918 with r-Pm to the volume of the distillation flask, the type of cooler and the distillation receiver.
