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.

ISO 6270-3:2018(E)
Introduction
This document is intended to give consistent conditions and procedures for the conditioning of pre-
prepared test specimens which are to be evaluated for defects which can develop when they are
subjected to humid ambient atmospheres such as constant condensation-water atmospheres or
alternating condensation-water atmospheres.
The tests are designed to clarify the behaviour of the test specimens in humid ambient atmospheres,
and to pinpoint any defects in the protection of the test specimens against corrosion. The testing of
coatings in these atmospheres does not necessarily give lifetime prediction data.
After conditioning, the test specimens are evaluated either in accordance with documents, such as the
appropriate part(s) of ISO 4628, or by procedures agreed between the interested parties.
