ASTM D3367-98

Standard Test Method for Plasticizer Sorption of Poly(Vinyl Chloride) Resins Under Applied Centrifugal Force

SCOPE
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 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. A specific safety precaution is given in 7.8.1. Note 1-This standard and ISO 4608-1984 are identical in all technical details.
