DIN ISO 9022-1:2016-12

Optical instruments are affected during their use by a number of different 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 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 overlapping 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 environmental parameters under controlled laboratory conditions. The DIN 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 instruments. DIN ISO 9022-1 defines terms relating to environmental tests of optical and photonic instruments, including additional assemblies from other fields (e. g. mechanical, chemical and electronic devices), and specifies basic features of testing. Regarding the latest edition from 2012 the Annex A was updated.
