2、1: 1994(E) ISO 9022=1:1994(E) 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. Esch member body interes

International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical C
4、ommission (IEC) on all matters of electrotechnical standardization. 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. Inter

11、Parameters which they are required to resist without sig- nificant 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
12、 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 per- formante. The manufacturer attempts to ensure, and the user naturally e
13、xpects, that instruments will resist the likely rigours of their environment throughout their life. This expectation tan be assessed by exposure of the instrument to a range of simulated environmental Parameters under controlled lab- oratory conditions. The severity of these conditions is often incr
14、eased 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 differen
15、t environments. The tests are based largely on IEC Standards, modified where necessary to take into account features special to Optical instruments. lt should be noted that, as a result of continuous progress in all fields, Optical instruments are no longer only precision-engineered Optical prod- uc
16、ts, 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 importante, t
17、hen 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 ISO 9022 and other appropriate International Standards will be necessary. -,-,- INTERNATIONAL STANDARD 0
18、ISO ISO 9022=1:1994(E) Optics and Optical instruments - Environmental test methods - Part 1: Definitions, extent of testing 1 Scope This part of ISO.9022 defines terms relating to en- vironmental tests of Optical instruments and of in- struments including Optical assemblies and Optical components, a
19、nd specifies basic features of testing. 2 Definitions For the purposes of nitions apply. ISO 9022, the following defi- 2.1 environmental test: Laboratory Simulation, usually severe, of the climatic, mechanical, biological and Chemical environmental influences acting on the specimen during assembly,
20、storage, transport and Operation, in Order to establish any changes in the behaviour of the specimen in a short time. 2.2 Optical instrument: Instrument whose function is mainly based on Optical phenomena. As a rule, the instrument consists of several assemblies and/or components. Optical instrument
21、s also include illumi- nation Systems, instruments with light conduction and instruments which, apart from Optical units, contain assemblies and/or components from other fields, e.g. electronie components. 2.3 Optical assembly: Functional unit consisting of several components, at least one of which
22、has an cytical function. 2.4 component (of an Optical instrument): Smallest unit generally consisting of one piece and one ma- terial. 2.5 representative Sample: Sample, e.g. an Optical part or piece of sheet metal, which differs from a component only in its geometry. 2.6 specimen: Instrument, assem
23、bly, component or representative Sample which is being tested. 2.7 test: Procedure by which the effect of applied Parameters on the properties of a specimen is deter- mined and assessed. 2.8 conditioning: Sum of the extemal influences acting on the specimen during the test, such as the conditioning
24、method and degree of severity em- ployed, and of the internal influences resulting from the state of Operation of the specimen, such as movements and/or temperature changes. 2.8.1 conditioning method: Individual or combined environmental influence(s) to which the specimen is submitted during the tes
