This document specifies methods of test for determining the main physical and chemical properties of sulfur used for compounding dry rubber.
Several of these properties can be determined by more than one test method and the user can choose the most appropriate method following the description of the test method principles provided under the corresponding clauses.
NOTE Typical levels for the relevant properties of sulfur for use as a rubber compounding ingredient are contained in Annex A, for information only.
