ASTM D2226 for various types of petroleum oils for rubber compounding use
1. Scope
1.1 This classification is intended to establish classification and test methods for certain types of oil used in extending and processing styrene-butadiene rubbers (SBR) and butadiene rubbers (BR). Its purpose is for classification only and not for specification.

1.2 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
