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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 4611 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 6, Ageing, chemical
and environmental resistance.
This third edition cancels and replaces the second edition (ISO 4611:1987), of which it constitutes a minor
revision, the main purpose of which was to update the normative references.

0 Introduction
0.1 Various test methods are available for the exposure of plastics to different aggressive agents acting in a
combined and simultaneous fashion, such as natural weathering. Other test methods are available for the
purpose of a separate evaluation of the action of individual aggressive agents. Among the latter there are, for
example, tests for the resistance to specific chemicals and to radiation in a definite spectral range.
For some applications, it may be desirable to evaluate the behaviour of the materials in a hot damp
atmosphere just below the saturation limit of water vapour, as well as in the presence of the liquid phase.
In these conditions, not only water absorption or leaching of some ingredients of the composition may be
observed but also degradation phenomena due to hydrolysis, exudation of plasticizers, etc.
It may also be desirable sometimes to evaluate the behaviour of materials in the presence of a highly
corrosive electrolyte, such as a sodium chloride solution (salt mist), which is the principal aggressive agent
present in marine environments and of particular importance in the case of nautical applications. It is well
known that sodium chloride has no noticeable action on the polymers that are the basic components of
plastics, and that salt solutions, owing to their higher osmotic pressure, are normally absorbed by plastics to a
lesser degree than pure water, but it cannot be assumed a priori that they have no action on composite
materials, containing fillers, reinforcing components or pigments, for instance.
Furthermore, the evaluation of the effect of salt mist can be very important for finished or semi-finished articles
which, while basically consisting of plastics materials, do contain some metallic elements, such as moulded-in
inserts, thin laminated foils, surface coatings applied by electro-plating or other procedures, or, lastly, metal
cores sheathed with plastics by extrusion or by dipping in pastes or fluidized-bed powders.
0.2 Methods and equipment for obtaining reproducible aggressive environments of the above types are well
known and have been described by International Standards relevant to other materials and IEC (International
Electrotechnical Commission) standards relevant to electrical and electronic components. The same
equipment and procedures described in these standards can also be employed for plastics, with appropriate
care and adjustments.
0.3 The present International Standard is intended to provide general guidance only, on the choice of
suitable equipment and procedures for obtaining the exposure conditions described above and for the
preparation of test specimens. It also only gives general guidance on the properties to be evaluated. Specific
details are given in the various ISO and IEC publications.
For the expression of results, the present International Standard follows, as far as possible, the same criteria
adopted in the existing test methods for the exposure to chemicals (see ISO 175) and to natural weathering or
artificial light (see ISO 4582).
0.4 These tests are intended to yield data about the effects of the described exposures on the materials;
however, a direct correlation between the experimental results and the behaviour in service is not to be
inferred.

INTERNATIONAL STANDARD ISO 4611:2008(E)
Plastics — Determination of the effects of exposure to damp
heat, water spray and salt mist
1 Scope
1.1 This International Standard specifies the conditions of exposure of plastics to
⎯ damp heat;
⎯ water spray;
⎯ salt mist;
and the methods for the evaluation of the change in some significant characteristics after given exposure
stages.
1.2 This International Standard is, in general, suitable for all plastics in the form of standard test specimens,
and finished articles or parts thereof.
1.3 This International Standard considers separately methods for the determination of
⎯ change in mass;
⎯ change in dimensions and appearance;
⎯ change in physical properties.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 9227, Corrosion tests in artificial atmospheres — Salt spray tests
IEC 60068-2-30, Environmental testing — Part 2-30: Tests — Test Db: Damp heat, cyclic (12 h + 12 h cycle)
IEC 60068-2-78, Environmental testing — Part 2-78: Tests — Test Cab: Damp heat, steady state
3 Principle
One or more properties are determined before and after given periods of exposure in the specified
environmental conditions, and any change in appearance is observed. If required, the determination of one or
more properties may be carried out after exposure and a subsequent drying treatment or a reconditioning
treatment carried out with the aim of obtaining the same state of equilibrium with atmospheric humidity as that
of the initial specimens.
