This standard BS 7164-24:1996 Chemical tests for raw and vulcanized rubber is classified in these ICS categories:
- 83.060 Rubber
1.1 This International Standard specifies three methods for the determination of free sulfur in vulcanized rubber: two versions of the copper spiral method, and the sodium sulfite method.
1.2 The copper spiral methods are also applicable, subject to the limitations described in clause 4, to unvulcanized compounds.
1.3 Annex A gives a table listing the sulfur contribution, as a percentage by mass, to these free-sulfur methods for various commercial accelerators.
