Historical Standard: ASTM D4818-89(1999) Standard Classification for Rubber Compounding Materials-Vulcanization Accelerators
SUPERSEDED (see Active link, below)
ASTM D4818
1. Scope
1.1 This classification describes vulcanization accelerators and defines their important chemical and physical characteristics. The properties outlined herein are useful for quality control; they can frequently be directly or indirectly related to the performance characteristics in rubber compounds.
1.2 Test Methods D1519, D4571, D4572 and D4574, for measurement of these properties, are not yet adapted for the vulcanization accelerators. Draft methods are being developed and will be submitted through Subcommittee D11.11 for processing and approval. A discussion of the reasons for determining these properties is contained in Section 6.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
