20、ithout 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. The environmental effects on optical ins
21、trument 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 ensure, and the user naturally expects, th
22、at 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 these conditions is often increased to obt
23、ain 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 simulate a variety of different environmen
24、ts. 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 products, but, depending on their range of a
25、pplication, 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, then ISO 9022 is applicable, but if ot
26、her 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.vi ISO 2015 All rights reservedBS ISO 9022-14:2015Optics and photonic
27、s Environmental test methods Part 14: Dew, hoarfrost, ice 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 equivalent conditions,
28、for their ability to resist the influence of dew, hoarfrost or ice. 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 dew, hoarfrost, or ice. 2 Norm

31、nvironmental conditions in a chamber or by transferring the specimen from a cold chamber to a conditioned room. Instrument parts not exposed to hoarfrost or icing conditions during normal use should be protected from exposure to such conditions during test. 4 Conditioning Table 1 shows the condition
32、ing methods 75 (dew), 76 (hoarfrost followed by the process of thawing), and 77 (ice covering followed by the process of thawing). Conditioning method 77 (ice covering followed by the process of thawing) includes two types of ice formation (see Annex A for details): rime ice: degree of severity 01 a
