The standards of the EN 3475 standard series describe test methods for electrical cables for aircraft use. Part 505 specifies a method of measuring the tensile properties of strands, conductors and braids. When required, it can also be used on cables. The standard shall be used together with EN 3475-100. This edition is intended to supersede DIN EN 505:2009-05. The following modifications have been made: a) expansion of the scope to include braids; b) incorporation of Annex A with a test method of the braid strength. This standard of the EN 3475 standard series 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 131-04-02 AA "Elektrische Leitungen" ("Electric cables") of the Aerospace Standards Committee at DIN.
