Scope

This document describes a method for determining the content of unconsumed inorganic free sulfur (Sx) during rubber vulcanization using chromatography. This method is primarily used to compare the free sulfur content in rubber with different degrees of vulcanization.
Note 1: In this document, "inorganic free sulfur" is replaced with "free sulfur".
Note 2: The free sulfur content determined by this method does not include the sulfur in the vulcanization agent.
