ISO 5843 establishes a list of equivalent terms used in the field of aerospace construction. This part of ISO 5843 gives those terms relating to environmental and operating conditions for aircraft equipment. NOTE — in addition to terms used in the three official ISO languages (English, French and Russian), this part of ISO 5843 gives the equivalent terms in the German language; these are published under the responsibility of the member body for Germany, F.R. (DIN). However, only the terms given in the official languages can be considered as ISO terms.
