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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

This document was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee
SC 9, General test methods for paints and varnishes in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 139, Paints and varnishes, in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 11997-1:2013), which has been technically
revised.
The main changes are as follows:
— Clause 3, Terms and definitions, has been added;
— in A.3.2.2 the designation of the fluorescent UV lams has been updated;
— the normative references have been updated.

Introduction
Coatings of paints, varnishes and similar materials are exposed to cyclic wet and dry corrosion and UV
exposure conditions using specified salt solutions in cabinets in order to simulate, in the laboratory, processes
occurring in aggressive outdoor conditions. Generally, valid correlations between such outdoor weathering
and laboratory testing cannot be expected because of the large number of factors influencing the breakdown
process. Certain relationships can only be expected if the effect on the coating of the important parameters
(e.g. nature of the pollutant, spectral distribution of the incident irradiance in the relevant photochemical
region, temperature of the specimen, type and cycle of wetting and relative humidity) is known. In contrast
to outdoor weathering, laboratory testing in a cabinet is performed with a reduced number of variables,
which can be controlled and therefore the effects are more reproducible.
The method described can give a means of checking that the quality of a paint or paint system is being
maintained. The method is intended to provide a more realistic simulation of these factors than is found
in traditional tests with continuous exposure to a static set of corrosive conditions. The method has been
found to be useful in comparing the cyclic salt spray resistance of different coatings. It is most useful in
providing relevant ratings for a series of coated panels exhibiting significant differences in cyclic salt spray/
UV exposure resistance tested at the same time and to the same test cycle.
The cycle specified in this part of ISO 11997 has been found useful for air-drying industrial maintenance
coatings on steel; other cycles may be used as required.
