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 (ISO 3233-1:2019)

This document specifies a method for determining the non-volatile matter by volume (NVV) of coating materials and related products by measuring the density of a dried coating for any specified temperature range and period of drying or curing. This method determines the non-volatile matter immediately after application. Using the non-volatile matter by volume results obtained in accordance with this document, it is possible to calculate the spreading rate of coating materials. The method specified in this document is the preferred method for air-drying materials. Its use for other materials has not yet been tested. Annex B gives an overview of the existing methods for determination of non-volatile-matter content and volume of non-volatile matter. This document is not applicable to coating materials in which the critical pigment volume concentration is exceeded.

Introduction
This method is used to measure the density and to determine the volume of a dry coating obtainable
from a given volume of liquid paint. This volume is considered to be the most meaningful measure of the
coverage (area of surface covered at a specified dry-film thickness per unit volume) of a paint, varnish
or related product. The value obtained by this method might not be the same as that calculated on the
basis of the addition of masses and volumes of the raw materials in a formulation. The volume occupied
by a combination of resin and solvent can be the same as, greater than or less than the combined volume
of the separate components, due to contraction or expansion of the resin and solvent. A second factor
affecting the volume of a dry coating formulation 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.
The values obtained for the non-volatile matter by volume are dependent on the temperature and time
of heating, and these conditions should be carefully considered for the material being tested.

Introduction
This method is used to measure the density and to determine the volume of a dry coating obtainable
from a given volume of liquid paint. This volume is considered to be the most meaningful measure of the
coverage (area of surface covered at a specified dry-film thickness per unit volume) of a paint, varnish
or related product. The value obtained by this method might not be the same as that calculated on the
basis of the addition of masses and volumes of the raw materials in a formulation. The volume occupied
by a combination of resin and solvent can be the same as, greater than or less than the combined volume
of the separate components, due to contraction or expansion of the resin and solvent. A second factor
affecting the volume of a dry coating formulation 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.
The values obtained for the non-volatile matter by volume are dependent on the temperature and time
of heating, and these conditions should be carefully considered for the material being tested.

DRAFT INTERNATIONAL STANDARD ISO/DIS 3233-1:2019(E)
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
1 Scope
This document specifies a method for determining the non-volatile matter by volume (NV ) of
V
coating materials and related products by measuring the density of a dried coating for any specified
temperature range and period of drying or curing. This method determines the non-volatile matter
immediately after application.
Using the non-volatile matter by volume results obtained in accordance with this part of ISO 3233, it is
possible to calculate the spreading rate of coating materials.
The method specified in this document is the preferred method for air-drying materials. Its use for
other materials still has to be tested.
Annex B gives an overview of the existing methods for determination of non-volatile-matter content
and volume of non-volatile matter.
This document is not applicable to coating materials in which the critical pigment volume concentration
is exceeded.

3.1
non-volatile matter
NV
residue by mass obtained by evaporation under specified conditions
Note 1 to entry: Instead of the term “non-volatile matter” different terms, such as solid, dry residue, dry matter, solid
matter, stoving residue are being used commonly with the respective abbreviations. The term “non-volatile matter”
which is also applied in ISO 3251 should be used together with the abbreviation “NV” instead of these terms.
Note 2 to entry: This part of ISO 3233 and ISO 3251 specify different conditions for the determination of NV.
Therefore in this part of ISO 3233, the symbol NV is used for non-volatile matter by mass.

3.2
non-volatile matter by volume
NV
V
percentage residue by volume obtained by evaporation under specified conditions
3.3
spreading rate
s
surface area that can be covered by a given quantity of coating material to give a dried film of requisite
thickness

3.4
practical dry-film density
ρ
p
practically determined density of a dried and cured coating
4 Principle
A receptacle (disc or plate) is weighed in air and in water (or other suitable liquid of known density),
coated with the product to be tested, dried and reweighed in air and in the same liquid. From these
measurements, the mass, the volume and hence the density of the dry coating are calculated. The non-
volatile matter by volume is calculated from the quotient of the density of the coating material and the
density of the dry film.
