T
10、he work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested 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-go
11、vernmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described
12、 in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

20、rmance 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 a laboratory or workshop) and on its geographical location. The environmental effects on optical instrument performance in the tropics and
21、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 ensure, and the user naturally expects, that instruments will resist the likely r
22、igours 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 these conditions is often increased to obtain meaningful results in a relatively
23、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 different environments. The tests are based largely on IEC
24、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 products, but, depending on their range of application, also contain additional ass
25、emblies 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, then ISO 9022 is applicable; but if other functions take precedence, then the
26、 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.vi ISO 2016 All rights reservedBS ISO 9022-9:2016INTERNATIONAL ST ANDARD ISO 9022-9:2016(E) Optics and phot
27、onics Environmental test methods Part 9: Solar radiation and weathering 1 Scope This part of ISO 9022 specifies the methods relating to the environmental tests of optical instruments including additional assemblies from other fields (e.g. mechanical, chemical and electronic devices), under equivalen
28、t conditions, for their ability to resist the effects of simulated solar radiation or laboratory weathering, which 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
29、surface, or in the lower atmosphere. The purpose of testing is to investigate to what extent the optical, climatic, mechanical, chemical and electrical (including electrostatic) performance characteristics of the specimen are affected by solar radiation or weathering (solar radiation, heat, and mois
30、ture). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

33、eral information and test conditions A radiation source capable of generating irradiance as specified in Table 1 on the 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 w
34、alls but not infrared radiation emitted from the chamber walls on account of the wall temperature. Ozone generated during 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 t
35、he radiation and the temperature within the exposure zone shall be specified in the relevant specification. In addition to the requirements specified above, IEC 60068-2-5 applies.

36、lar radiation See 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 increase long-term degradation of optics, surfaces and other materials. In outdoor conditions, material degradation can therefore occur
37、 even when passing the test according to this part of ISO 9022. NOTE 2 An irradiance of 1 kW/m 2corresponds to the intensity of global radiation. The latter is the total radiation incident upon a horizontal area of the earths surface and is, with the sun being at the zenith, composed of direct solar
38、 radiation and solar radiation diffusely reflected from the atmosphere. The global radiation is not constant and has therefore been determined by the International Commission on Illumination (CIE) on the basis of solar constant l 0= 1,35 kW/m 2(see CIE No. 20/1972). NOTE 3 Degree of severity 01 repr
39、esents extreme natural stress and is preferably used to determine thermal influences. Degree of severity 02 represents medium-degree natural stress over a long period and is preferably used to determine thermal, photomechanical and ageing influences. Degrees of severity 03 and 04 do not represent tr
40、ue influences but are preferably used to determine photochemical influences and to achieve artificial ageing. In addition, heating effects on specimens of low thermal capacity may be determined.

General guidance and specific instructions on how to perform an accelerated weathering test using an appropriately filtered xenon-arc light source are provided in ISO 4892-1 and ISO 4892-2.
48、The laboratory light source shall be appropriately filtered xenon-arc lamp(s) meeting the specifications of ISO 4892-1 and ISO 4892-2. Exposure parameters according to ISO 4892-2:2013, Table 3 and Table 4, Cycle A-1 and Cycle A-4 are commonly used for the simulation of outdoor exposures, while Cycle
49、 B-2 and Cycle B-5 are for interior exposures behind window glass and Cycle B-3 and Cycle B-6 are for hot light fastness, e.g. for automotive interior devices.
