适用范围：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. 2 The copper spiral methods are also applicable, subject to the limitations described in clause 4, to unvulcanized compounds. 3 Annex A gives a table listing the sulfur contri-bution, as a percentage by mass, to these free-sulfur methods for various commercial accelerators.
