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.
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.
International Standard ISO 2811-1 was prepared by Technical Committee
ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test
methods for paints and varnishes.
Together with the other parts, this part of ISO 2811 cancels and replaces
ISO 2811:1974, which has been technically revised.
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 ISO 2811-1:1997(E)
Paints and varnishes — Determination of density —
Part 1:
Pyknometer method
1  Scope
This part of ISO 2811 is one of a series of standards dealing with the sampling and testing of paints, varnishes and
related products.
It specifies a method for determining the density of paints, varnishes and related products using a pyknometer.
The method is limited to materials of low or medium viscosity at the temperature of test. The Hubbard pyknometer
can be used for highly viscous materials.
2  Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this part of
ISO 2811. At the time of publication, the editions indicated were valid. All standards are subject to revision, and
parties to agreements based on this part of ISO 2811 are encouraged to investigate the possibility of applying the
most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid
International Standards.
ISO 1512:1991, Paints and varnishes — Sampling of products in liquid or paste form.
ISO 1513:1992, Paints and varnishes — Examination and preparation of samples for testing.
ISO 3696:1987, Water for analytical laboratory use — Specification and test methods.
3  Definition
For the purposes of this part of ISO 2811, the following definition applies.
3.1  density, r: The mass divided by the volume of a portion of a material, expressed in grams per millilitre (g/ml).
4  Principle
A pyknometer is filled with the product under test. The density is calculated from the mass of the product in the
pyknometer and the known volume of the pyknometer.

ISO
ISO 2811-1:1997(E)
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 – 0,5) °C is
specified in this part of ISO 2811. It may be more convenient, however, to carry out comparative testing at some
other agreed temperature, for example (20 – 0,5) °C as specified by relevant weights and measures legislation (see
also annex B, clause B.2).
The test sample and pyknometer 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 test.
6  Apparatus
Ordinary laboratory apparatus and glassware, together with the following:
6.1  Pyknometer
6.1.1  Metal pyknometer, with a volume of either 50 ml or 100 ml, a circular cross-section and a cylindrical form,
made of a smoothly finished corrosion-resistant material with a snugly fitting lid having a hole in its centre. The
inside of the lid shall be concave (see figure 1).
or
6.1.2  Glass pyknometer, with a volume in the range 10 ml to 100 ml (either Gay-Lussac or Hubbard type) (see
figures 2a and 2b).
6.2  Analytical balance, accurate to 1 mg for pyknometers less than 50 ml in volume or accurate to 10 mg for
50 ml to 100 ml pyknometers.
6.3  Thermometer, accurate to 0,2 °C and graduated at intervals of 0,2 °C or finer.
6.4  Temperature-controlled chamber, capable of accommodating the balanc
