18、number of different environmental and handling parameters which they are required 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 th

19、e laboratory or workshop) and on its geographical location. The environmental 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 overlap

20、ping effects on instrument performance.The manufacturer 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 cumulated exposure of the instrument to a range of simulated env

21、ironmental parameters under controlled laboratory conditions. The cumulative combination, 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 instr

22、uments to appropriate environ-mental conditions, the ISO 9022 series contains 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

23、instruments.lt should be noted that, 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 assemblies from other fields. For this reason, the principal func

24、tion of the instrument must be assessed to determine which International Standard 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 th

25、e field concerned should be applied. Cases may arise where application of both the relevant part of ISO 9022 and other appropriate International Standards is necessary.Optics and photonics Environmental test methods Part 22: Combined cold, dry heat or temperature change with bump or random vibration

26、 5 DIN ISO 9022-22:2012-10 1 ScopeThis 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 vibr

27、ation, in cold, dry heat or temperature 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 ref

31、nformation and test conditionsExposure 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, correspo

32、nd to real conditions under use. In 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 optic

33、al instruments and instruments containing optical components and/or their electronic assembly, in which the system is switched off or in operation, and exposed to their operating, storage, shipping or other temperature cycles, combined with sinusoidal or random vibration and operation with under or

34、excess voltage.The aforementioned methods 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

35、is therefore not standardized.6 DIN ISO 9022-22:2012-10 The values of temperatures specified in Table 1 are selected from ISO 9022-2, conditioning methods 10, 11 and 14.The values of mechanical loads specified in Table 1 are selected from ISO 9022-3, conditioning methods 31 and 37.Conditioning metho

36、ds 10, 11 or 14 are combined with conditioning methods 31 or 37. Combinations are listed in Table 1.Testing shall be conducted in accordance with the requirements of ISO 9022-3.The fixture for the specimen shall meet the requirements of IEC 60068-2-47 and shall be thermally insulated, if appropriate

37、.If the specimen is mounted on shock absorbers, time shall be allowed for temperature stabilization of the absorber elements.For the purposes of this part of ISO 9022, the value of gnis rounded up to the next highest integer, i.e. 10 m/s2.5 Conditioning5.1 GeneralIf temperature change testing is per

The temperature of the specimen and of the test chamber shall be the same.When testing optical instruments, a half-sine shock pulse shall be applied. The specimen shall be subjected to one thousand shocks in each dir

39、ection along each axis or a specific number of shocks shall be defined.Random vibration shall be digitally controlled. The acceleration power spectral density shall be controlled with a vibration control system according to IEC 60068-2-64.Other parameters such as temperature, cold or dry heat, tempe

47、here is no formation of condensation, hoarfrost or ice.6.3 Test sequence with temperature changeThe first temperature cycle commences at ambient atmospheric conditions. The duration of a cycle is normally between 7 h and 8 h, regardless of temperature differences within the cycles, depending on the

48、required severity. The mean heating and cooling rate of the chamber shall allow a continuous variation of temperature at the specimen (see Figure 1) or shall be stipulated in the relevant specification.NOTE Conditioning method 14 of ISO 9022-2 specifies a test chamber temperature rate of change in the range between 0,2 K and 2 K per minute. However, higher rates may be appropriate depending on the individual application. Rates of 1 K per minute to 10
