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. 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

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 11997-2:2000), which has been technically
revised. The main technical changes are:
a) alternative test procedures have been added as an informative annex;
b) the supplementary test conditions (formerly Annex A) have been incorporated in the test report.
ISO 11997 consists of the following parts, under the general title Paints and varnishes — Determination
of resistance to cyclic corrosion conditions:
— Part 1: Wet(salt fog)/dry/humidity
— Part 2: Wet (salt fog)/dry/humidity/UV light
This part of ISO 11997 is equivalent to ASTM D 5894, Standard Practice for Cyclic Salt Fog/UV Exposure of
Painted Metal, (Alternating Exposures in a Fog/Dry Cabinet and a UV/Condensation Cabinet).

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 serie
