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 4895 was prepared by Technical CommitteeISO/TC 61, Plastics, Subcommittee SC 12, Thermosetting materials.This second edition cancels and replaces the first edition (ISO 4895:1987),which has been technically revised.SIST EN ISO 4895:2000
© ISOISO 4895:1997(E)iiiIntroductionThe tendency of liquid epoxy resins to crystallize varies depending onfactors such as basic composition, purity, additives, homogeneity andwater content, in addition to external factors such as storage historyand ambient temperature.As it is rather difficult to indicate the tendency quantitatively by observationand comparison, the tendency is therefore to express the results byobserving, at intervals, the changes in fluidity and appearance of samples.SIST EN ISO 4895:2000

ScopeThis International Standard specifies a method for determining the tendency of liquid epoxy resins to crystallize. Thetendency to crystallize is determined by observing, at specified time intervals, changes in fluidity and the onset ofcrystallization.2
