Paints and varnishes - Determination of density - Part 1: Pycnometer method (ISO 2811-1:2016)
ISO 2811-1:2016 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 2811-1:2016)
Dieser Teil von ISO 2811 legt ein Verfahren zum Bestimmen der Dichte von Beschichtungsstoffen und ähn-lichen 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 2811-1:2016)
ISO 2811-1:2016 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 l'ISO 3507) peut être utilisé pour les produits à forte viscosité.
Barve in laki - Ugotavljanje gostote - 1. del: Metoda s piknometrom (ISO 2811-1:2016)
Ta del standarda ISO 2811 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 on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 35, Paints and varnishes, Subcommittee SC 9,
General test methods for paints and varnishes.
This third edition cancels and replaces the second edition (ISO 2811-1:2011), which has been technically
revised with the following changes:
a) the information on the accuracy of the analytical balance (6.2) and the thermometer (6.3) was
changed;
b) a requirement was added that the sample shall be free from air bubbles;
c) the spelling of pycnometer was corrected.
ISO 2811 consists of the following parts, under the general title Paints and varnishes — Determination of
density:
— Part 1: Pycnometer method
— Part 2: Immersed body (plummet) method
— Part 3: Oscillation method
— Part 4: Pressure cup method

INTERNATIONAL STANDARD ISO 2811-1:2016(E)
Paints and varnishes — Determination of density —
Part 1:
Pycnometer method
1 Scope
This part of ISO 2811 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.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 1513, Paints and varnishes — Examination and preparation of test samples
ISO 3696, Water for analytical laboratory use — Specification and test methods
ISO 15528, Paints, varnishes and raw materials for paints and varnishes — Sampling
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
density
ρ
mass divided by the volume of a portion of a material
Note 1 to entry: It is expressed in grams per cubic centimetre.
4 Principle
A pycnometer is filled with the product under test. The density is calculated from the mass of the
product in the pycnometer and the known volume of the pycnometer.
5 Temperature
The effect of temperature on density is highly significant with respect to filling properties, and varies
with the type of product.
For international reference purposes, it is essential to standardize one test temperature, and
(23,0 ± 0,5) °C is specified in this part of ISO 2811. It can be more convenient, however, to carry out
comparative testing at some other agreed temperature, for example (20,0 ± 0,5) °C, as specified by
relevant weights and measures legislation (see B.2).
