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.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
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 fourth edition cancels and replaces the third edition (ISO 11997-1:2017), which has been technically
revised.
The main changes are as follows:
— the general warning and warnings for each chemical material have been added;
— the dry air supply for cycle C has been revised
— the normative references have been updated

Introduction
Coatings of paints, varnishes and similar materials are exposed to one of four cycles of wet and dry
conditions specified in this document (see Annex A to Annex D), using specified salt solutions in a cabinet in
order to simulate, in the laboratory, processes occurring in aggressive outdoor conditions, such as marine
environments. Generally, correlation between such outdoor weathering and laboratory testing cannot
be expected because of the large number of factors influencing the breakdown process. Correlation can
only be expected if the effect on the coating of important parameters (e.g. the nature of the pollutant, the
spectral distribution of the incident irradiance in the relevant photochemical region, the temperature of the
specimen, the 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
