Paints and varnishes - Determination of density - Part 1: Pycnometer method (ISO 2811-1:2023)
This document specifies a method for determining the density of paints, varnishes and related products using a metal or Gay-Lussac pycnometer.
The method is limited to materials of low or medium viscosity at the temperature of test. The Hubbard pycnometer (see ISO 3507) can be used for highly viscous materials.
Beschichtungsstoffe - Bestimmung der Dichte - Teil 1: Pyknometer-Verfahren (ISO 2811-1:2023)
Dieses Dokument legt ein Verfahren zum Bestimmen der Dichte von Beschichtungsstoffen und ähnlichen Produkten mit einem Metallpyknometer oder einem Pyknometer nach Gay Lussac fest.
Das Verfahren ist nur für Stoffe mit niedriger oder mittlerer Viskosität bei der Prüftemperatur anwendbar. Das Pyknometer nach Hubbard (siehe ISO 3507) kann für hochviskose Stoffe verwendet werden.
Peintures et vernis - Détermination de la masse volumique - Partie 1: Méthode pycnométrique (ISO 2811-1:2023)
Le présent document spécifie une méthode de détermination de la masse volumique des peintures, vernis et produits assimilés au moyen d’un pycnomètre en métal ou d’un pycnomètre de Gay-Lussac.
La méthode est limitée aux produits de viscosité faible ou moyenne à la température d’essai. Le pycnomètre de Hubbard (voir ISO 3507) peut être utilisé pour les produits à forte viscosité.
Barve in laki - Določanje gostote - 1. del: Metoda s piknometrom (ISO 2811-1:2023)
Standard ISO 2811-1:2016 določa metodo za ugotavljanje gostote barv, lakov in sorodnih izdelkov z uporabo kovinskega ali Gay-Lussacovega piknometra.
Metoda je omejena na materiale z nizko ali srednjo viskoznostjo pri preskusni temperaturi. Hubbardov piknometer (glej standard ISO 3507) se lahko uporablja za materiale z visoko viskoznostjo.

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.
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

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 fourth edition cancels and replaces the third edition (ISO 2811-1:2016), which has been technically
revised.
The main changes are as follows:
— a requirement to de-aerate the sample prior to the determination in order to achieve reproducible
results for the density has been added to 8.2;
— the text has been editorially revised and the normative references have been updated.
A list of all parts in the ISO 2811 series can be found on the ISO website.
