5.1 This test method provides a quantitative measure of the relative plasticizer absorption of general-purpose poly(vinyl chloride) resins under standard temperature conditions. Plasticizer sorption thus defined is one of the criteria useful for the description of the powder blend characteristics of poly(vinyl chloride) resins.

1.1 This test method covers the determination of the plasticizer sorption of poly(vinyl chloride) (PVC) homopolymers using a controlled centrifugal force.

1.2 The values stated in SI units are to be regarded as the standard.

1.3 This test method references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this test method.

Note 1: This standard is equivalent to ISO 4608.

1.4 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.

1.5 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.
