Paints and varnishes - Determination of viscosity using rotational viscometers - Part 2: Relative measurement of viscosity using disc or ball spindles at specified speeds (ISO 2884-2:2024)

ISO 2884-2:2003 specifies a general procedure for determining the viscosity of paints, varnishes and related products with a viscosity of up to 34 pascal seconds. It is applicable mainly during production and thinning.

Beschichtungsstoffe - Bestimmung der Viskosität mit Rotationsviskosimetern - Teil 2: Relative Viskositätsmessung mit Scheiben- oder Kugelspindeln bei festgelegten Drehzahlen (ISO 2884-2:2024)

Dieses Dokument legt ein allgemeines Verfahren zum Bestimmen der Viskosität von Beschichtungsstoffen, wie Lacke, Anstrichstoffe und verwandten Produkten sowie Bindemittel fest. Das Verfahren wird hauptsächlich angewendet, um die relative Viskosität eines Produktes zu bestimmen und diese beim Verdünnen während eines Fertigungsprozesses zu überwachen. Es beschreibt eine relative Messung der Viskosität mit Hilfe von Scheiben- oder Kugelspindeln bei bestimmten Geschwindigkeiten.
Das in diesem Dokument festgelegte Verfahren ist für alle Beschichtungsstoffe geeignet, unabhängig davon, ob sie newtonsches Verhalten zeigen oder nicht. Es kann auch bei Stoffen, die Dispersionen von Teilchen enthalten, angewendet werden.

L'ISO 2884-2:2003 spécifie un mode opératoire général à suivre pour déterminer la viscosité des peintures, des vernis et des produits assimilés dans une gamme de viscosités allant jusqu'à 34 pascals seconde. Elle s'applique essentiellement à la production et à la dilution.

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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

This document was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee
SC 9, General test methods for paints and varnishes, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 139, Paints and varnishes, in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 2884-2:2003), which has been technically
revised.
The main changes are as follows:
— terminology and symbols have been adapted to ISO 3219-1;
— a statement has been added that this document refers to a relative value for viscosity;
— description of the test procedure including the test report has been updated;
— the normative references have been updated.
