The work ofpreparing International Standards is normally carried out through ISOtechnical committees. Each member body interested in a subject for whicha technical committee has been established has the right to be representedon that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISOcollaborates closely with the International Electrotechnical Commission(IEC) on all matters of electrotechnical standardization.Draft International Standards adopted by the technical committees arecirculated to the member bodies for voting. Publication as an InternationalStandard requires approval by at least 75 % of the member bodies castinga vote.International Standard ISO 4608 was prepared by Technical CommitteeISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials.This third edition cancels and replaces the second edition (ISO 4608:1984),which has been technically revised.SIST EN ISO 4608:2000

© ISOISO 4608:1998(E)1Plastics — Homopolymer and copolymer resins of vinyl chloridefor general use — Determination of plasticizer absorption at roomtemperature1
ScopeThis International Standard specifies a method for determining plasticizer absorption at room temperature. It isapplicable 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 adry mixture.The results give a general indication of the plasticizer absorption of a resin at room temperature. They indicate theusefulness of resins for the manufacture of plasticized dry blends, particularly when taken in conjunction with theresults of plasticizer absorption tests under hot conditions.2

At the time of publication, the edition indicated was valid. All standards are subject torevision, and parties to agreements based on this International Standard are encouraged to investigate thepossibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintainregisters of currently valid International Standards.ISO 1385-1:1977, Phthalate esters for industrial use — Methods of test — Part 1: General.3
PrincipleAn excess of bis-(2-ethylhexyl) phthalate (DOP) is added to a specified amount of resin. The mixture is thencentrifuged under defined conditions and the amount of plasticizer retained by the resin determined.4
