15、d photonics Environmental test methods Part 1: Definitions, extent of testing 5 IntroductionOptical 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
16、specifications.The type and severity of these parameters depend on the conditions of use of the instrument (for example, in a laboratory or workshop) and on its geographical location. The environmental effects on optical instrument performance in the tropics and subtropics are totally different from
17、 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 ensure, and the user naturally expects, that instruments will resist the likely rigours of their environment throughout
18、 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
19、 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
20、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 products, but, depending on their range of application, also contain additional assemblies from other fields. For this reaso
21、n, 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, then ISO 9022 is applicable; but if other functions take precedence, then the appropriate International Standard in th
22、e field concerned should be applied. Cases may arise where application of both ISO 9022 and other appropriate International Standards will be necessary.Optics and photonics Environmental test methods Part 9: Solar radiation and weathering6DIN ISO 9022-9:2016-12 1 ScopeThis part of ISO 9022 specifies
23、 the methods relating to the 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 effects of simulated solar radiation or laboratory weathering, wh
24、ich is a combination of simulated solar radiation, heat, and moisture. It is applicable to instruments that may be exposed to sunlight during operation or unsheltered storage on the earths surface, or in the lower atmosphere.The purpose of testing is to investigate to what extent the optical, climat
25、ic, mechanical, chemical and electrical (including electrostatic) performance characteristics of the specimen are affected by solar radiation or weathering (solar radiation, heat, and moisture).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this doc

29、specimen surface or in a plane specified in the relevant specification is installed in a heated test chamber. The data shall include any radiation reflected from the test chamber walls but not infrared radiation emitted from the chamber walls on account of the wall temperature.Ozone generated during
30、 exposure shall be removed from the test chamber.The position and mounting of the specimen, the characteristics of its support and the location of the test points for measuring the radiation and the temperature within the exposure zone shall be specified in the relevant specification.In addition to
31、the requirements specified above, IEC 60068-2-5 applies.7 DIN ISO 9022-9:2016-12 4 Conditioning methods4.1 Conditioning method 20: Solar radiationSee Table 2.NOTE 1 Wavelengths in the atmospheric window below 280 nm are not covered by this part of ISO 9022. However, wavelengths below 280 nm can incr
32、ease long-term degradation of optics, surfaces and other materials. In outdoor conditions, material degradation can therefore occur even when passing the test according to this part of ISO 9022.NOTE 2 An irradiance of 1 kW/m2corresponds to the intensity of global radiation. The latter is the total r
33、adiation incident upon a horizontal area of the earths surface and is, with the sun being at the zenith, composed of direct solar radiation and solar radiation diffusely reflected from the atmosphere. The global radiation is not constant and has therefore been determined by the International Commiss
34、ion on Illumination (CIE) on the basis of solar constant l0= 1,35 kW/m2(see CIE No. 20/1972).Table 1 Spectral energy distribution of the radiation sourceSpectral range Ultraviolet Visible InfraredWavelength band nm 280 to 320beyond 320 to 400beyond 400 to 520beyond 520 to 640beyond 640 to 780beyond
