SIST EN ISO 2884-1:2025

Paints and varnishes - Determination of viscosity using rotational viscometers - Part 1: Absolute viscosity measurement with cone-plate measuring geometry at high shear rates (ISO 2884-1:2024)

This part of ISO 2884 is one of a series dealing with the sampling and testing of paints, varnishes and related
products.
It supplements ISO 2431:1993, Paints and varnishes — Determination of flow time by use of flow cups.
It specifies the general procedure to be followed in determining the dynamic viscosity of paints, varnishes and
related products at a rate of shear between 9 000 s?1 and 12 000 s?1.
The value obtained gives information about the resistance offered by the material to brushing, spraying and roller
coating during application.
The method specified in this part of ISO 2884 is suitable for all paints and varnishes whether they are Newtonian in
behaviour or not. Materials containing dispersions of large particles will produce spurious results.

Beschichtungsstoffe - Bestimmung der Viskosität mit Rotationsviskosimetern - Teil 1: Absolute Viskositätsmessung mit Kegel-Platte-Messgeometrie bei hohen Scherraten (ISO 2884-1:2024)

Dieses Dokument legt das allgemeine Verfahren zum Bestimmen der dynamischen Viskosität von unpigmentierten Beschichtungsstoffen, wie Lacke, Anstrichstoffe und ähnliche Produkte, sowie Bindemittel in einem Scherratenbereich zwischen 9 000 s-1 und 12 000 s-1 fest. Es beschreibt ein Absolutverfahren zur Viskositätsmessung mit der Kegel-Platte-Messgeometrie bei hohen Scherraten.
Der gemessene Wert gibt Auskunft über den Widerstand des Stoffes beim Auftragen durch Streichen, Spritzen und Rollen.
Das in diesem Dokument festgelegte Verfahren ist für alle Beschichtungsstoffe geeignet, unabhängig davon, ob sie newtonsches Verhalten zeigen oder nicht. Bei Stoffen, die Dispersionen von großen Teilchen enthalten, ist zu erwarten, dass die zu verwendende Messgeometrie angepasst wird.

Peintures et vernis - Détermination de la viscosité au moyen de viscosimètres rotatifs - Partie 1: Mesurage de la viscosité absolue par géométrie de mesure cône/plateau à des vitesses de cisaillement élevées (ISO 2884-1:2024)

La présente partie de l'ISO 2884 fait partie d'une série traitant de l'échantillonnage et de l'essai des peintures,
vernis et produits assimilés.
Elle s'ajoute à l'ISO 2431:1993, Peintures et vernis — Détermination du temps d'écoulement au moyen de coupes
d'écoulement.
Elle spécifie la méthode générale à suivre pour déterminer la viscosité dynamique des peintures, vernis et produits
assimilés à un gradient de vitesse compris entre 9 000 s?1 et 12 000 s?1.
La valeur obtenue donne des informations sur la résistance du produit à la brosse, aux pulvérisations et à
l'application au rouleau pendant l'application.
La méthode spécifiée dans la présente partie de l'ISO 2884 convient pour toutes les peintures et vernis, à
comportement newtonien ou non. Si les produits contiennent des particules de grande taille, les résultats seront
faussés.

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. Each 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,
governmental 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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
