The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested

11、 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 Comm

12、ission (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

13、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).

20、ffected 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 exam

21、ple, 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 regions. Individual parameters cause a variety of different and overlapp

22、ing 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

23、 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 9

24、022 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. As a result of continuous progress in all fields, opt

25、ical 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 is to be assessed to determine which International Standard should

26、 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 can arise where application of both ISO 9022 and other appropriate I

27、nternational Standards will be necessary.vi ISO 2015 All rights reservedBS ISO 9022-17:2015Optics and photonics Environmental test methods Part 17: Combined contamination, solar radiation 1 Scope This part of ISO 9022 specifies the methods relating to the environmental tests of optical instruments a

28、nd including additional assemblies from other fields (e.g. mechanical, chemical, and electronic devices) under equivalent conditions, for their ability to resist the influence of combined contamination and solar radiation. “Contamination”, as used in this part of ISO 9022, means the contact of optic

29、al instruments with corrosive chemical substances (hereafter called test agents). Complete instruments or assemblies are, however, not be tested to this part of ISO 9022 except for special reasons (refer to ISO 9022-12). As a rule, representative substrates are used as specimens. The tests described

30、 in this part of ISO 9022 are designed for the selection of materials and components for instruments likely to be subjected to combined contamination and solar radiation during service life, rather than for regular production control. The purpose of testing is to investigate the resistance of an ins

31、trument, and in particular, of instrument surfaces, coatings, or synthetic materials, to a short-time exposure to the test agents combined with solar radiation. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for

34、evere than separate exposure to any of the conditions cited. The test shall be conducted in ambient atmospheric conditions in accordance with ISO 9022-1. The test agents listed in Tables 1 and 2 were selected from ISO 9022-12, conditioning methods 86 and 89. The test shall be conducted in accordance

35、 with the requirements of ISO 9022-9 and ISO 9022-12. The surface of the specimens shall be orientated so that the test agents do not flow away during testing. If liquid test agents are used, enough drops shall be deposited in one place on the surface to form a circular spot of approximately 10 mm d

36、iameter. During the test, the test agents may not flow into each other. In the case of spreading liquids, several specimens should be used if necessary.

37、spread evenly and thinly in the form of the spot described above (thickness approximately 0,1 mm). It should be noted that heating of the test agents can cause them to spread during the test. Test agents which evaporate during the test shall not be replaced. The relevant specification might require

38、testing of a complete instrument or assembly if such instrument or assembly would be likely to encounter, during its service life, complete flooding rather than partial contamination only. After having preconditioned such specimens as described in ISO 9022-12, the surface shall be completely and cop

39、iously sprayed, by means of an atomizer, with a test agent specified in the relevant specification. Any test agent evaporating during exposure shall not be replaced. 3.2 Specimens For specimens, see ISO 9022-12. 4 Conditioning Tables 1 and 2 show combinations of degrees of severity from ISO 9022-9 a
