1.1 This practice covers a variety of extraction techniques for antioxidant and slip additives used in polyolefins. Typically, the extracted additives are separated and quantified using a chromatographic technique such as the procedure explained in Test Method D6953. Chromatographic analysis of the extracts is not included in this practice.
1.2 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.
Note 1: There is no known ISO equivalent to this standard.
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.
