Paints and varnishes - Determination of density - Part 2: Immersed body (plummet) method (ISO 2811-2:2011)
ISO 2811-2:2011 specifies a method for determining the density of paints, varnishes and related products, using balls or other round bodies as immersion bodies (plummets).
The method is limited to materials of low or medium viscosity, and is particularly suitable for production control.
Beschichtungsstoffe - Bestimmung der Dichte - Teil 2: Tauchkörper-Verfahren (ISO 2811-2:2011)
Dieser Teil von ISO 2811 legt ein Verfahren zum Bestimmen der Dichte von Beschichtungsstoffen und
ähnlichen Produkten mit Kugeln oder anderen rotationssymmetrischen Körpern als Tauchkörper fest.
Das Verfahren ist nur für Stoffe mit niedriger oder mittlerer Viskosität bei der Prüftemperatur anwendbar, es
eignet sich besonders als Betriebsprüfverfahren.
Peintures et vernis - Détermination de la masse volumique - Partie 2: Méthode par immersion d'un corps (plongeur) (ISO 2811-2:2011)
L'ISO 2811-2:2011 spécifie une méthode de détermination de la masse volumique des peintures, vernis et produits assimilés au moyen de sphères ou d'autres corps ronds utilisés comme corps immergés (plongeurs).
Cette méthode est limitée aux produits de viscosité faible ou moyenne, et convient particulièrement au contrôle de production.
Barve in laki - Določevanje gostote - 2. del: Metoda s potapljanjem (ISO 2811-2:2011)
Ta del ISO 2811 določa metodo določevanja gostote barv, lakov in sorodnih proizvodov s potapljanjem žog ali drugih okroglih teles. Metoda je omejena na materiale nizke ali srednje viskoznosti in je predvsem primerna za nadzor nad proizvodnjo.

ISO 2811-2:2011(E) iv © ISO 2011 – All rights reserved 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. 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. ISO 2811-2 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 2811-2:1997), which has been technically revised. The main changes are the following. a) The unit for the density has been changed from grams per millilitre to grams per cubic centimetre, because this is the more common SI unit. b) The determination in duplicate has been changed to a single determination. c) The information on calibration procedure has been changed to an example only and the status of Annex B has been changed from normative to informative. d) The precision data has been updated by an interlaboratory test. e) The normative references have been updated. ISO 2811 consists of the following parts, under the general title Paints and varnishes — Determination of density: ⎯ Part 1: Pyknometer method ⎯ Part 2: Immersed body (plummet) method ⎯ Part 3: Oscillation method ⎯ Part 4: Pressure cup method
INTERNATIONAL STANDARD ISO 2811-2:2011(E) © ISO 2011 – All rights reserved 1 Paints and varnishes — Determination of density — Part 2: Immersed body (plummet) method 1 Scope This part of ISO 2811 specifies a method for determining the density of paints, varnishes and related products, using balls or other round bodies as immersion bodies (plummets). The method is limited to materials of low or medium viscosity, and is particularly suitable for production control. 2 Normative references The following referenced documents are indispensable for the application of this document. 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 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 It is expressed in grams per cubic centimetre. 4 Principle The method is based on Archimedes' principle. A container is filled with the product under test and placed on the analytical balance. The plummet is attached to a tripod and is immersed in the product under test. The density is calculated from the balance readings before the plummet is immersed in the material under test and after it is immersed. 5 Temperature The effect of temperature on density is highly significant with respect to filling properties, and varies with the type of product.

ISO 2811-2:2011(E) 2 © ISO 2011 – All rights reserved 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. However, it can be more convenient 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). The test sample and plummet shall be conditioned to the specified or agreed temperature, and it shall be ensured that the temperature variation does not exceed 0,5 °C during testing. 6 Apparatus Ordinary laboratory apparatus and glassware, together with the following. 6.1 Plummets, of non-corrodible metal, e.g. copper-zinc alloy (brass), stainless steel or aluminium, as illustrated in Figure 1.
