DIN EN 3197:2011-03

The standard DIN EN 3197 provides instructions on the methods to be used when designing, selecting, manufacturing, installing, repairing and modifying aircraft electrical and optical interconnection networks, now called EWIS (Electrical Wiring Interconnection System) and OFIS (Optical Fibre Interconnection Systems), subject to the limitations defined in this standard. It is recognized that the installation practices described in this standard do not necessarily represent the full requirements for a safe and satisfactory electrical and optical interconnection system. In the event of a conflict between the text of this document and the references cited herein, the text of this document takes precedence. However, no specification in this standard shall override the specific requirements of a Design Authority, the Airworthiness Requirements, applicable laws or any regulation from the regulatory authorities, unless a specific exemption has been obtained. This standard has been prepared by ASD-STAN, Technical Section Electrics, Avionics, with the participation of German experts of the Aerospace Standards Committee. The European Committee for Standardization (CEN) declared the Aerospace and Defence Industries Association of Europe (ASD-STAN) responsible for the preparation of European standards (EN) for the field of aerospace. The responsible German standardization committee is Working Committee NA 131-04-08 AA "Installationskomponenten" ("Harness components") of the Aerospace Standards Committee at DIN.
