15、meters 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.
16、 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 overlapping effects on instrument performance.The manufacturer attempts to en
17、sure, 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 th
18、ese 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 sim
19、ulate 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, optical instruments are no longer only precision-engineered optical product
20、s, 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 be used for testing. If the optical function is of primary importance, t
21、hen 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 International Standards will be necessary.Optics and photonics Environment
22、al test methods Part 17: Combined contamination, solar radiationDIN ISO 9022-17:2016-025 1 ScopeThis part of ISO 9022 specifies the methods relating to the environmental tests of optical instruments and including additional assemblies from other fields (e.g. mechanical, chemical, and electronic devi
23、ces) 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 optical instruments with corrosive chemical substances (hereafter called test agents).Complete instrument
24、s 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 in this part of ISO 9022 are designed for the selection of materials and components for instruments l
25、ikely 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 instrument, and in particular, of instrument surfaces, coatings, or synthetic materials, to a short-time e
26、xposure to the test agents combined with solar radiation.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest

28、 Environmental test methods Part 12: Contamination3 General information and test conditions3.1 GeneralExposure of the specimen to the combined stress conditions renders the test much more severe than separate exposure to any of the conditions cited.The test shall be conducted in ambient atmospheric
29、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 with the requirements of ISO 9022-9 and ISO 9022-12.The surface of the specimens shall be orientated so that the
30、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 diameter. During the test, the test agents may not flow into each other. In the case of spreading liquids, several s
31、pecimens should be used if necessary. Viscous or paste DIN ISO 9022-17:2016-026 liquids shall be 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
32、 which evaporate during the test shall not be replaced.The relevant specification might require 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 pr
33、econditioned such specimens as described in ISO 9022-12, the surface shall be completely and copiously 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 SpecimensFor specimens, see ISO 902
