Paints and varnishes — Determination of viscosity using rotational viscometers — Part 2: Relative measurement of viscosity using disc or ball spindles at specified speeds
This document specifies a general procedure for determining the viscosity of paints, varnishes and related products, as well as binders. The method is primarily used to determine the relative viscosity of a product and to monitor this while thinning during a manufacturing process. It describes a relative measurement of viscosity using disc or ball spindles at specified speeds. The method specified in this document is suitable for all paints and varnishes whether they are Newtonian in behaviour or not. It can also be applied to materials containing dispersions of particles.
Peintures et vernis — Détermination de la viscosité au moyen de viscosimètres rotatifs — Partie 2: Mesurage relatif de la viscosité avec des agitateurs à disque ou à bille à des vitesses spécifiées
Le présent document spécifie un mode opératoire général pour la détermination de la viscosité des peintures, vernis et produits assimilés, ainsi que des liants. La méthode est principalement utilisée pour déterminer la viscosité relative d’un produit et pour la contrôler pendant la dilution au cours du processus de fabrication. Il décrit une méthode de mesurage relatif de la viscosité avec des agitateurs à disque ou à bille à des vitesses spécifiées. La méthode spécifiée dans le présent document convient pour l’ensemble des peintures et vernis, à comportement d’écoulement newtonien ou non. Elle peut également être appliquée à des produits contenant des dispersions de particules.

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.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
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.
