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 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 9022 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO9022-2 was prepared by Technical Committee ISO/TC172, Optics and optical
instruments, Subcommittee SC 1, Fundamental standards.
This second edition cancels and replaces the first edition (ISO 9022-2:1994), Tables 2, 3 and 7 of which have been
technically revised.
ISO 9022 consists of the following parts, under the general title Optics and optical instruments — Environmental test
methods:

ISO 9022-2:2002(E)
Introduction
Optical instruments are affected during their use by a number of different environmental parameters which they are
required to resist without significant reduction in performance.
The type and severity of these parameters depend on the conditions of use of the instrument (for example, in the
laboratory or workshop) and on its geographical location. The environmental effects on optical instrument
performance in the tropics and subtropics are totally different from those found when they are used in the arctic
regions. Individual parameters cause a variety of different and overlapping effects on instrument performance.
The manufacturer attempts to ensure, and the user naturally expects, that instruments will resist the likely rigours of
their environment throughout their life. This expectation can be assessed by exposure of the instrument to a range of
simulated environmental parameters under controlled laboratory conditions. The severity of these conditions is often
increased to obtain meaningful results in a relatively short period of time.
In order to allow assessment and comparison of the response of optical instruments to appropriate environmental
conditions, ISO 9022 contains details of a number of laboratory tests which reliably simulate a variety of different
environments. The tests are based largely on IEC standards, modified where necessary to take into account features
special to optical instruments.
It should be noted that, as a result of continuous progress in all fields, optical instruments are no longer only
precision-engineered optical products, but, depending on their range of application, also contain additional
assemblies from other fields. For this reason, the principal function of the instrument must be assessed to determine
which International Standard should be used for testing. If the optical function is of primary importance, then
ISO 9022 is applicable, but if other functions take precedence then the appropriate International Standard in the field
concerned should be applied. Cases may arise where application of both ISO9022 and other appropriate
International Standards will be necessary.

testing
3 General information and test conditions
The specimen is exposed to climatic stress in conditioning chambers or cabinets providing air circulation.
The size of the specimens and their arrangement shall be such as to ensure a uniform conditioning of all specimens.
Where moisture condensation is likely to occur, the condensate shall be prevented from dripping onto the specimen.
Where heat-dissipating specimens are involved, the relevant specification shall state the number, method of
installation and location of the heat sensors.
◦
WARNING — Persons entering test chambers with dew-point temperatures of equal to or greater than 38 C
must be equipped with breathing apparatus (e.g. conditioning methods 12, 13 and 16).
