ASTM D2226-93(2022) - 1.10.2022
 
Significance and Use

3.1?The composition of the oil in rubber compounds has a large effect on the characteristics and use of the compounds. This classification divides the oils into broad categories for descriptive purposes.

 
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.3?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
