20、022-3:2015ISO 9022-3:2015(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 and to remain within defined specifications. The type and severity of these par
21、ameters 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 arctic regio
22、ns. 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
23、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
24、 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
25、 instruments. 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
26、 is to 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
27、can arise where application of both ISO 9022 and other appropriate International Standards will be necessary.vi ISO 2015 All rights reservedBS ISO 9022-3:2015Optics and photonics Environmental test methods Part 3: Mechanical stress 1 Scope This part of ISO 9022 specifies the methods relating to the
28、environmental tests of optical instruments including additional assemblies from other fields (e.g. mechanical, chemical, and electronic devices), under equivalent conditions, for their ability to resist the influence of mechanical stress. The purpose of the testing is to investigate to what extent t
29、he optical, climatic, mechanical, chemical, and electrical (including electrostatic) performance characteristics of the specimen are affected by mechanical stress. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable f
