DIN EN ISO 4608:2024-02

This document specifies a method for determining plasticizer absorption at room temperature. This document is applicable to PVC for general applications and extender 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 test procedure makes it possible to determine the quantity of plasticizer that a polymer absorbs at room temperature to form a dry blend. Knowledge of the plasticizer absorption of a polymer at room temperature provides an indication of the usefulness of resins for the manufacture of plasticised dry blends, particularly when taken in conjunction with the results of plasticizer absorption tests under hot conditions. Committee NA 054-02-10 AA "Thermoplast-Formmassen" ("Thermoplastic materials") at DIN Standards Committee Plastics (FNK) is responsible for this standard.
