Cellular plastics and rubbers - Determination of apparent density (ISO 845:2006)

This International Standard specifies a method of determining a) the compressive strength and corresponding relative deformation or b) the compressive stress at 10 % relative deformation and c) when desired, the compressive modulus of rigid cellular plastics.

Schaumstoffe aus Kautschuk und Kunststoffen - Bestimmung der Rohdichte (ISO 845:2006)

Diese Internationale Norm beschreibt ein Verfahren zur Bestimmung der Stoffdichte und der Materialdichte von Schaumstoffen aus Kunststoffen und Kautschuk.
Falls an dem zu prüfenden Material eine beim Formen/Extrudieren gebildete Schmelzhaut vorhanden ist, kann/können die Stoffdichte und/oder die Materialdichte bestimmt werden. Falls das Material keine Schmelz¬haut aufweist, darf die Benennung „"Stoffdichte“" nicht verwendet werden.
Für umgeformte Materialien darf ein anderes Verfahren angewendet werden, z. B. das Auftriebsverfahren.

Caoutchoucs et plastiques alvéolaires - Détermination de la masse volumique apparente (ISO 845:2006)

L'ISO 845:2006 spécifie une méthode pour la détermination de la masse volumique globale et de la masse volumique apparente de la partie intérieure («âme») des caoutchoucs et des plastiques alvéolaires.
Si le matériau soumis à essai comprend des peaux formées en cours de moulage ou d'extrusion, on peut déterminer la masse volumique apparente globale ou la masse volumique de l'âme, ou les deux. Si le matériau ne comporte pas de peaux formées pendant le moulage ou l'extrusion, le terme «masse volumique globale» n'est pas applicable.
