DESCRIPTION
BS ISO 19242:2021
This standard BS ISO 19242:2021 Rubber. Determination of total sulfur content by ion chromatography is classified in these ICS categories:
- 83.060 Rubber
This document specifies a method for the determination of the total sulfur content of raw rubber and unvulcanized or vulcanized rubber compounds by ion chromatography following the preparation of a sample solution using either a tubular furnace combustion or an oxygen combustion flask method.
The tubular furnace combustion method is applicable for rubbers with sulfur content less than 0,1 % as it 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 an insoluble metal sulfate, such as barium sulfate (CAS 7727?43?7).
