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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information.
The committee responsible for this document is 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 13803:2000), which has been technically
revised. The main technical changes are:
a) the symbols have been adapted to the revision of ISO 2813;
b) an introduction and a principle clause have been added;
c) the supplementary test conditions have been included in the test report;
d) the normative references have been updated.

ISO 13803:2014(E)
Introduction
High quality surfaces are expected to have a clear and brilliant appearance. Microstructures can cause
a milky appearance. This effect is described as haze. A high gloss surface with microscopic texture has
diffused light with low intensity adjacent to the main direction of reflection. The majority of the incident
light is reflected in the specular direction which will make the surface appear high glossy with image
forming qualities, but with a milky haziness on top of it.
The phenomenon haze can be seen on high gloss surfaces only. Therefore, the 20° geometry is used
like with a gloss meter. The aperture range of a 20° gloss meter is 1,8°. Two additional sensors next to
the gloss detector measure the intensity of the diffused light responsible for haze. Thus, the specularly
reflected and the scattered light are measured simultaneously. In order to better correlate with the
visual perception, haze is displayed in a logarithmic scale – the lower the haze reading the better the
surface.
INTERNATIONAL STANDARD ISO 13803:2014(E)
Paints and varnishes — Determination of haze on paint
films at 20°
1 Scope
This International Standard specifies a test method for determining the haze of coatings. The method is
suitable for the haze measurement of non-textures coatings on plane, opaque substrates.
The use of the 20° geometry means that the method is closely related to the measurement of gloss at 20°
in ISO 2813. The application of this method is intended to give improved differentiation between high-
gloss surfaces, for example in the field of assessment of dispersion characteristics.
