ISO 4626:1980

This method is applicable to organic liquids that boil between 30 and 300 C at normal pressure, and that are chemically stable and do not corrode the apparatus during the distillation such as hydrocarbons, esters, alcohols, ketones, ethers and similar products. The principle consists in distillation of a 100 ml test portion under prescribed conditions, systematic observation of thermometer readings and volumes of condensate and calculation of the results from these data with correction to standard atmospheric pressure.
