Paints and varnishes - Determination of viscosity using rotational viscometers - Part 2: Relative measurement of viscosity using disc or ball spindles at specified speeds (ISO/DIS 2884-2:2023)

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.

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 documents 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions 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

This document was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee
SC 9, General test methods for paints and varnishes.
This second edition cancels and replaces the first edition (ISO 2884-2:2003), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— terminology and symbols have been adapted to ISO 3219-1;
— an indication has been added that this document refers to a relative value for viscosity;
— description of the test procedure including the test report has been adapted to ISO 3219-3;
— the text has been editorially revised and the normative references have been updated.
A list of all parts in the ISO 2884 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
