Rubber, vulcanized — Quantitative analysis methods for volatilized sulfur and sulfur compounds under heating conditions — Part 2: Sulfur compounds

Scope

This document specifies methods for determining the amount of sulfur compounds volatilized from vulcanized rubber under heating conditions using gas chromatograph (GC) or ion chromatograph (IC). The methods apply to the sulfur compounds which are hydrogen sulfide (H2S), carbonyl sulfide (COS), carbon disulfide (CS2) and sulfur dioxide (SO2).
The methods cannot be used above the thermal decomposition temperature of the rubber.

Note The methods determine the amount of sulfur compounds that volatilize from the vulcanized rubber under heating conditions, and do not determine the total amount of sulfur compounds that can volatilize from the vulcanized rubber.
