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 Commis-
sion (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
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.
Attention is drawn to the possibility that some of the elements of this part of ISO 11997 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 11997-2 was prepared by Technical Committee ISO/TC 35, Paints and varnishes,
Subcommittee SC 9, General test methods for paints and varnishes.
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
Annex A forms a normative part of this part of ISO 11997.

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 ag-
gressive 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 cy-
cle of wetting and relative humidity) is known. In contrast to outdoor weathering, laboratory testing in a cabinet is per-
formed with a reduced number of variables, which can be controlled and therefore the effects are more reproducible.
The method described may 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
thesametestcycle.
