标准范围
This International Standard specifies a method for the determination of the total sulfur content ofraw rubber and unvulcanized or vulcanized rubber compounds by ion chromatography following thepreparation of a sample solution using either a tubular furnace combustion or an oxygen combustionflask method.The tubular furnace combustion method is applicable for rubbers with sulfur content less than 0,1 % asit is possible that the oxygen combustion flask method will not give sufficiently accurate results.The oxygen combustion flask method is not applicable to rubbers containing a metal salt that forms aninsoluble metal sulfate, such as barium sulfate.
