Plastics - Resins in the liquid state or as emulsions or dispersions - Determination of apparent viscosity by the Brookfield Test method (ISO 2555:1989)

Specification of a method for determining an apparent viscosity of resins in a liquid state, using one of the types of rotational viskosimeter described in this standard. A spindle or disc is driven at constant rotational frequency in the product being studied. The resistance exerted by the fluid on the spindle, which depends on the viscosity of the product, cause a torque, which is indicated by a suitable meter. The application of this method to specific products is detailed in annex A. The viscosimeters types A, B and C permit visscosity measurements from 0,02 Pa.s to 60 000 Pa.s.

Kunststoffe - Harze im flüssigen Zustand, als Emulsionen oder Dispersionen - Bestimmung der scheinbaren Viskosität nach dem Brookfield-Verfahren (ISO 2555:1989)

Diese Internationale Norm legt für Harze im flüssigen oder in einem vergleichbaren Zustand ein Verfahren zur Bestimmung der scheinbaren Viskosität nach Brookfield fest, bei dem eine der in dieser Norm beschriebenen Ausführungen eines Rotationsviskosimeters verwendet wird. Die Anwendung dieses Verfahrens auf spezielle Produkte wird im einzelnen in Anhang A beschrieben. Viskosimeter in den Ausführungen A, B und C ermöglichen Messungen der Viskosität in einem Bereich von 0,02 Pa.s (20 cP) bis 60 000 Pa.s (60x106 cP).

Plastiques - Résines à l'état liquide ou en émulsions ou dispersions - Détermination de la viscosité apparente selon le Procédé Brookfield (ISO 2555:1989)

La présente Norme internationale prescrit une méthode pour ladétermination de la viscosité apparente selon le Procédé Brookfield,des résines à l'état liquide ou assimilé, à l'aide d'un des types desviscosimètres rotatifs décrits dans la présente Norme internationale.L'application de cette méthode à des produits particuliers est détaillée dans l'annexe A.Les viscosimètres des types A, B et C permettent des rnesuragesde viscosité entre 0,02 Pa-s (20 cP) et 60 000 Pa-s (60 x 10 puissance 6 cP).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bodies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 2555 was prepared by Technical Committee ISO/TC 61,
Plas tics .
This second edition cancels and replaces the first edition (ISO 2555 : 19741, of which it
constitutes a technical revision.
