Historical Standard: Standard Classification for Rubber Compounding Materials\u2014Vulcanization Accelerators<\/h4>\n
\n

ASTM D4818<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1<\/span> This classification covers 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.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> Test Methods D1519<\/span>, D4571<\/span>, D4572<\/span> and D4574<\/span>, 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<\/span>.<\/p>\n<\/p><\/div>\n
