DISCLAIMER
This Redline version provides you with a quick and easy way to compare the main changes
between this edition of the standard and its previous edition. It doesn’t capture all single
changes such as punctuation but highlights the modifications providing customers with
the most valuable information. Therefore it is important to note that this Redline version is
not the official ISO standard and that the users must consult with the clean version of the
standard, which is the official standard, for implementation purposes.

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).
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 voteAttention 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).

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 and to remain within
defined specifications.
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 s
