ISO 4608:1998, Plastics - Homopolymer and copolymer resins of vinyl chloride for general use - Determination of plasticizer absorption at room temperature

This International Standard specifies a method for determining plasticizer absorption at room temperature. It is applicable to PVC general-purpose resins and filler resins (designated “G” and “F” in ISO 1060-1:1998, Plastics — Homopolymer and copolymer resins of vinyl chloride — Part 1: Designation system and basis for specifications).The object of the test is to determine the quantity of plasticizer absorbed by a resin at room temperature to give a dry mixture.The results give a general indication of the plasticizer absorption of a resin at room temperature. They indicate the usefulness of resins for the manufacture of plasticized dry blends, particularly when taken in conjunction with the results of plasticizer absorption tests under hot conditions.
