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 aircraft reliability. NOTE — In addition to the terms given in the three official ISO languages (English, French and Russian), this part of ISO 5843 gives the equivalent terms in German. These terms have been included at the request of ISO Technical Committee ISO/TC 20, and 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.
