Each member body interested in a subject for which a technical committee has been established has the right to b

12、e represented on that committee. International organizations, governmental and non-governmental, 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.International Standar

13、ds are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Interna

14、tional Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

19、edBS ISO 9022-22:2012ISO 9022-22:2012(E)IntroductionOptical and photonic instruments, including additional assemblies from other fields (e.g. mechanical, chemical and electronic devices) are affected during their use by a number of different environmental and handling parameters which they are requi

20、red to resist without significant reduction in performance, while still remaining 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

21、effects on optical instrument performance in tropical and subtropical climates are totally different from those found when they are used in the arctic regions. Individual parameters cause a variety of different and overlapping effects on instrument performance.The manufacturer attempts to ensure, an

22、d the user naturally expects, that instruments will resist the likely rigours of their environment throughout their life. This expectation can be assessed by cumulated exposure of the instrument to a range of simulated environmental parameters under controlled laboratory conditions. The cumulative c

23、ombination, degree of severity and sequence of these conditions can be selected 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 environ-mental conditions, the ISO 9022 series contains

24、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 take into account features specific to optical instruments.lt should be noted that, as a result of continuous progress in all

25、 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 reason, the principal function of the instrument must be assessed to determine which International Stand

26、ard should be used for testing. If the optical function is of primary importance, then the relevant part of ISO 9022 is applicable, but if other functions take precedence, then the appropriate Inter national Standard in the field concerned should be applied. Cases may arise where application of both

27、 the relevant part of ISO 9022 and other appropriate International Standards is necessary.

28、is part of ISO 9022 specifies methods for the testing of optical instruments, including additional assemblies from other fields (e.g. mechanical, chemical and electronic devices) under equivalent conditions, for their ability to resist combined bump or random vibration, in cold, dry heat or temperat

29、ure change.The purpose of testing is to investigate to what extent the optical, thermal, chemical and electrical performance characteristics of the specimen are affected by combined cold, dry heat or temperature change with bump or random vibration.2 Normative referencesThe following referenced docu

33、re of the specimen to combined stress conditions renders the test much more severe than separate exposure to any of the environmental conditions cited. Stress conditions such as cold, dry heat or temperature change, combined with bump or random vibration, correspond to real conditions under use. In

34、the case of the lifetime test, tests with higher degrees of severity for time reduction, damage-provoked tests, etc., combined test methods such as Burn-In, Run-In or Environmental Stress Screening (ESS) are useful.Burn-In, Run-In or ESS are test methods for optical instruments and instruments conta

36、thods of combined tests are suitable to force potential faults to be detected during first use and to eliminate them before delivery. There are stress factors with different impacts. The choice of combination of test methods should be specific to the products and is therefore not standardized.INTERN
