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).

This first edition of ISO 3233-3 cancels and replaces ISO 23811:2009, which has been technically revised
and, in addition to the change in number, contains the following changes:
— symbols have been harmonized with those used in ISO 3233-1 and ISO 3233-2;
— determination of dry film thickness has been added;
— statement on the density of the solvents of waterborne systems has been added;
— informative annex (Annex D) for an overview on the existing methods for determination of non-
volatile matter content and volume of non-volatile matter has been added;
— text has been editorially revised and Normative References has been updated.
ISO 3233 consists of the following parts, under the general title Paints and varnishes — Determination of
percentage volume of non-volatile matter:
— Part 1: Method using a coated test panel to determine non-volatile matter and to determine dry film
density by the Archimedes principle
— Part 2: Method using the determination of non-volatile-matter content in accordance with ISO 3251 and
determination of dry film density on coated test panels by the Archimedes principle
— Part 3: Determination by calculation from the non-volatile-matter content determined in accordance
with ISO 3251, the density of the coating material and the density of the solvent in the coating material

ISO 3233-3:2015(E)
Introduction
This method is used to determine the volume of the dry coating obtainable using a coating material by
calculation of the percentage volume of non-volatile matter. The value obtained by this method might
not be the same as that measured or calculated by adding together the masses and volumes of the raw
materials in a formulation. The volume occupied by a combination of resin and solvent might be the
same as, greater than, or less than the combined volume of the separate components, since contraction
or expansion of resin and the solvent can occur. A second factor affecting the volume of a dry coating is
the degree to which the spaces between pigment particles are filled with binder. A third factor is the use
of volatile components in reactive systems that, by their reaction, change into non-volatile film-building
materials, i.e. amines and reactive solvents in high-build two-component coating materials.
Above and close to the critical pigment volume concentration, the volume of a dry paint film is greater
than the theoretical volume, due to an increase in unfilled voids between pigment particles. The porosity
of the film means that this method is unsuitable.
Other methods for determination of the percentage volume of non-volatile matter are described in
ISO 3233-1 and ISO 3233-2. The method described in this part of ISO 3233 is a quick method which
needs only the results of the non-volatile matter and the density of the coating material and the density
of the solvents for the calculation. The precision of the method depends mainly on the determination
of the non-volatile matter content and the unknown densities. But the precision of the combination
of measurements and calculation is better than the precision of pure calculation methods with no
measurements. The simple practical method is often used in the automotive industry, especially for
commercial vehicles.
The method described in this part of ISO 3233 differs from the methods described in ASTM D 2697 and
ASTM D 5201-05, 5.5 and gives different results.
INTERNATIONAL STANDARD ISO 3233-3:2015(E)
Paints and varnishes — Determination of the percentage
volume of non-volatile matter —
Part 3:
Determination by calculation from the non-volatile-
matter content determined in accordance with ISO 3251,
the density of the coating material and the density of the
solvent in the coating material
1 Scope
This part of ISO 3233 a simple practical method for calculating the non-volatile matter by volume, NV ,
V
of a coating material from the non-volatile-matter content, NV, the density of the coating material, and
the density of the solvents. Using the non-volatile matter by volume results and the density obtained
in accordance with this part of ISO 3233, it is possible to calculate the theoretical spreading rate of a
coating material.
This part of ISO 3233 is not applicable to coating materials which exceed the critical pigment volume
concentration (CPVC).
