12、) the standard has been editorially updated; c) the text of International Standard ISO 9022-2:2015 has been adopted in its entirety.

14、rameters 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 locatio
15、n. 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
16、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 parameters under controlled laboratory conditions. The severity of
17、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 9022 contains details of a number of laboratory tests which reliably s
18、imulate 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 produ
19、cts, 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,
20、 then ISO 9022 is applicable, but if other functions take precedence then the 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.5DIN ISO 9022-2:2015-061 Scope
21、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 equivalent conditions, for their ability to resist the influence of temperature and/or h
22、umidity.The purpose of the testing is to investigate to what extent optical, climatic, mechanical, chemical, and electrical (including electrostatic) performance characteristics of the specimen are affected by temperature and/or humidity.2 Normative referencesThe following documents, in whole or in
23、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 edition of the referenced document (including any amendments) applies.ISO 9022-1, Optics and photonics Environmental t
24、est methods Part 1: Definitions, extent of testing3 General information and test conditionsThe specimen is exposed to climatic stress in conditioning chambers or cabinets providing air circulation.The size of the specimens and their arrangement shall be such as to ensure a uniform conditioning of al
25、l specimens. Where condensation is likely to occur, the condensate shall be prevented from dripping onto the specimen.Where heat-dissipating specimens are involved, the relevant specification shall state the number, method of installation and location of the heat sensors.WARNING Persons entering tes
26、t chambers with dew-point temperatures of equal to or greater than 38 C must be equipped with breathing apparatus (e.g. conditioning methods 12, 13, and 16).4 Conditioning4.1 GeneralThe required exposure time shall not commence until all parts of the specimen have reached a temperature within at lea
27、st 3 K of the test chamber temperature. For heat-dissipating specimens, the period of exposure or dwell time (conditioning methods 14 and 15) shall not begin, or end, until the temperature of the specimen changes not more than 1 K within 1 h at the stabilized test chamber temperature. The last hour
28、of the temperature soaking time shall be considered to be the first hour of the exposure period.6DIN ISO 9022-2:2015-064.2 Constant stress conditions4.2.1 GeneralDuring exposure to constant stress conditions, the temperature shall be changed sufficiently slowly to prevent the specimen from being dam
29、aged. When testing to conditioning methods 11 and 12, the maximum relative humidity also applies to the temperature change phase. The relevant specification shall state whether dew formation (condensation) on the specimen is acceptable.4.2.2 Conditioning method 10: ColdSee Table 1.Table 1 Degrees of
