scope:
NEN-ISO 19242 specifies a method for the determination of the total sulfur content of raw rubber, unvulcanized or vulcanized rubber compounds by ion chromatography following the preparation of sample solution using either tubular furnace combustion or oxygen combustion flask method. Tubular furnace combustion method is recommended for rubbers with sulfur content less than 0,1 % as oxygen combustion flask method may not give a result with sufficient accuracy. Oxygen combustion flask method is not applicable to rubbers with metal salt that forms insoluble metal sulfate such as barium sulfate.
