DIN EN 6059-502:2010-09

The DIN EN 6059 standard series describes test methods for protection sleeves for installation with electrical cables in aircraft. Part 502 specifies a method of assessing the behaviour of protection sleeves or conduits subject to an external electric arc, ever at 115 Vac or 230 Vac 400 Hz. The primary aim of this test is to produce, in a controlled fashion, electric arcs at the immediate vicinity of a protection sleeve or conduit and to examine possible consequences on cables inside this protection, which are supposed to be maintained in a safe condition. These electric arcs are representative of those, which may occur in service when a typical cable bundle is severely damaged. In order to optimize thickness and mass of such protection, it is necessary to associate a current limit to each sleeves or conduits construction. Two levels of prospective fault current are specified for all protection sizes. The standards of the EN 6059 standard series have 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" ("Installation components") of the Aerospace Standards Committee at DIN.
