ISO 2811-3

Paints and varnishes — Determination of density — Part 3: Oscillation method

ISO 2811-3:2011 specifies a method for determining the density of paints, varnishes and related products using an oscillator. The method is suitable for all materials, including paste-like coatings. If a pressure-resistant type of apparatus is used, the method is also applicable to aerosols.

Peintures et vernis — Détermination de la masse volumique — Partie 3: Méthode par oscillation

L'ISO 2811-3:2011 spécifie une méthode de détermination de la masse volumique des peintures, vernis et produits assimilés au moyen d'un oscillateur. La méthode convient pour tous les produits, y compris les revêtements de consistance pâteuse. Si un type d'appareillage résistant à la pression est utilisé, la méthode est également applicable aux aérosols.

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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
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
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 third edition cancels and replaces the second edition (ISO 2811-3:2011), which has been technically
revised.
The main changes are as follows:
— a requirement has been added to 8.2, to de-aerate the sample prior to the determination in order to
achieve reproducible results for the density;
— Table B.3 has been deleted;
— a bibliography has been added.
A list of all parts in the ISO 2811 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
complete listing of these bodies can be found at www.iso.org/members.html.

4 Principle
A glass or stainless-steel U-tube is filled with the product under test. The tube is clamped at both ends
and then subjected to oscillation. The resonance frequency of the filled tube varies with the mass
contained in the tube, i.e. the density of the product under test.
5 Temperature
The effect of temperature on density is highly significa
