introduction
ISO (International Organization for Standardization) is a global alliance of national standards bodies (ISO member bodies). The development of international standards is usually carried out through ISO technical committees. Each member institution interested in a subject on which a technical committee has been established has the right to be represented on that committee. International governmental and non-governmental organizations liaising with ISO are also involved in this work. ISO works closely with the International Electrotechnical Commission (IEC) on all matters of electrical standardization.

The procedures used to develop this document and those used for further maintenance are described in Part 1 of the ISO/IEC Directive. In particular, attention should be paid to the different approval criteria required for different types of ISO documents. This document has been drafted in accordance with the editing rules of ISO/IEC Directive Part 2 (see iso.org/directives).

Please note that certain elements of this document may be subject to patent rights. ISO is not responsible for identifying any or all such patents. Details of any patent rights identified during the preparation of the document will be found in the introduction and/or in the list of patent claims received by ISO (see iso.org/patents).

The committee responsible for this document is ISO/TC 35, Paints and Varnishes, Subcommittee SC 9, Common Test Methods for Paints and varnishes.

The third edition cancels and replaces the second edition (ISO 2811-1:2011), which was technically revised with the following changes:

a) The accuracy information of the analytical balance (6.2) and thermometer (6.3) has been changed;

b) The requirement that the sample is free of bubbles is increased;

c) The spelling of the pycnometer has been corrected.

ISO 2811-1-2016 Paints and varnishes – Determination of density

ISO 2811 consists of the following parts, under the general heading Paints and varnishes – Determination of density:

– Part 1: Pycnometer method

– Part 2: Immersion (plunge) method

– Part 3: Oscillation method

– Part 4: Pressure cup method

1 Range
This part of ISO 2811 specifies methods for determining the density of paints, varnishes and related products using metal or Gay-Lussac pygometers.

The method is limited to materials with low or medium viscosity at test temperatures. Hubbard bottles (see ISO 3507) can be used for high viscosity materials.
