Specifies a method, the principle of which is based on evaporation of a test portion under specified conditions, using special apparatus, and weighing of the residue after evaporation. Details the procedure and provides information on the expression of results and the data to be included in the test report.
Abstract
Overview
ISO 5789:1979 specifies a standardized method for the determination of non-volatile residue in fluorinated hydrocarbons used in industrial applications. This international standard ensures the precise measurement of residue contents by employing evaporation of a test sample under controlled conditions, followed by the accurate weighing of the residue left behind. Developed by ISO Technical Committee ISO/TC 47 on Chemistry, this method provides a reliable basis for quality control and safety assessments in industries utilizing fluorinated hydrocarbons.
