13、 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 example, in the laboratory or workshop) and on its geo
14、graphical 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 overlapping effects on instrument performance.The manufact
15、urer 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 parameters under controlled laboratory conditions.
16、 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 9022 contains details of a number of laboratory tests
17、 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.It should be noted that, as a result of continuous progress in all fields, optical instruments are no long
18、er 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 instruments shall be assessed to determine which International Standard should be used for testing. If the
19、 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 International Standards will
20、 be necessary.5DIN ISO 9022-4:2015-061 ScopeThis 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
21、resist the influence of salt mist.Exposure to salt mist mainly results in the corrosion of metals. Effects might also occur by way of clogging or binding of moving parts.The purpose of the testing is to assess, as early as possible, the ability of the instrument, and particularly of the surfaces and
22、 protective coatings of the instrument, to resist the effects of a salt atmosphere.Normally, representative samples or complete small units are used for testing. Complete large instruments or assemblies are only tested as specified in this part of ISO 9022 in exceptional cases.2 Normative references
