Scope

This document specifies methods for determining the amount of sulfur volatilized from vulcanized rubber under heating conditions using high performance liquid chromatograph (HPLC). The methods apply only to the sulfur which chemical formula is S8.

The methods cannot be used above the thermal decomposition temperature of the rubber.

NOTE 1 The methods determine the amount of sulfur that volatilizes from vulcanized rubber under heating conditions, and do not determine the total amount of sulfur that can volatilize from the vulcanized rubber.

NOTE 2 Depending on the method adopted to collect sulfur volatilized from vulcanized rubber, the test results can be different between the two methods.
