This part of ISO 1183 specifies three methods for the determination of the density of non-cellular plastics in
the form of void-free moulded or extruded objects, as well as powders, flakes and granules.
Method A: Immersion method, for solid plastics (except for powders) in void-free form.
Method B: Liquid pyknometer method, for particles, powders, flakes, granules or small pieces of
finished parts.
Method C: Titration method, for plastics in any void-free form.
NOTE This part of ISO 1183 is applicable to pellets as long as they are void-free. Density is frequently used to follow
variations in physical structure or composition of plastic materials. Density may also be useful in assessing the uniformity
of samples or specimens. Often the density of plastic materials will depend upon the choice of specimen preparation
method. When this is the case, precise details of the specimen preparation method will have to be included in the
appropriate material specification. This note is applicable to all three methods.
Dieser Teil von ISO 1183 legt drei Verfahren zur Bestimmung der Dichte von nicht verschäumten Kunststoffen fest, die in Form von blasenfrei geformten oder extrudierten Gegenständen, aber auch als Pulver, Flocken und Granulat vorliegen. - Verfahren A: Eintauchverfahren, für blasenfreie feste Kunststoffe (ausgenommen Pulver). - Verfahren B: Verfahren mit Flüssigkeitspyknometer, für Teilchen, Pulver, Flocken, Granulat oder zerkleinerte Fertigteile. - Verfahren C: Titrationsverfahren, für blasenfreie Kunststoffe in jeder Form.
