19、pean foreword This document (EN 6059-503:2017) has been prepared by the Aerospace and Defence Industries Association of Europe - Standardization (ASD-STAN). After enquiries and votes carried out in accordance with the rules of this Association, this European Standard has received the approval of the
20、 National Associations and the Official Services of the member countries of ASD, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2018, and conflicting na
21、tional standards shall be withdrawn at the latest by February 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 6059-
22、503:2012. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, F

BS EN 6059503:2017EN 6059-503:2017 (E) 4 1 Scope This European Standa
24、rd specifies a method of assessing the behaviour and temperature increase of EMI protection sleeves or conduits when subject to permanent and/or fault currents in the shielding of the conduit or sleeve material and their effect on the cables within the cable sleeve. It shall be used together with EN
25、 3475-100. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (includin
26、g any amendments) applies. EN 3475-100, Aerospace series - Cables, electrical, aircraft use - Test methods - Part 100: General 3 Preparation of specimens 3.1 General Each specimen having 750 mm to 1 000 mm useful length between the supports, shall be installed horizontally in front of a screen and l
27、ightly stretched at the ends to avoid any slack during the test. The test shall be carried out at ambient temperature Ta(typically 20 C) in a chamber where the whole unit shall be sheltered from draughts. An extraction shall be provided but only operated after completion of the test. To identify the
28、 appearance of smoke, a screen with black and white horizontal bands or any other device shall be used. 3.2 Preparation of specimens Specimens will be installed horizontally in a box with a background striped in white and black. To detect smoke appearance the box will be transparent in the front. It
29、 will be closed to avoid any heat exchange. An exhaust fan will be added above the box in case of toxic fume generation (it shall not function during the test but only at the end and this to not disrupts the heating). As described below two (2) circuits are provided: the first one is for the connect
30、ing power and the second one is for the measurement. BS EN 6059503:2017EN 6059-503:2017 (E) 5 3.3 Connecting system 3.3.1 General To ensure that the contacts bringing the current consider all the strands of the shielding, the following mounting is to be assured: A split ring will be placed between t
31、he bundle ant the sleeve. A CuNi flat braid of a section of 3,44 mm2will be connected to the sleeve with a metallic clamp. Terminal lugs will be fixed at the flat braid extremities. 3.3.2 First case (Figure 1) This proposition considers specimens without connectors at the ends. Key 1 sleeve 2 cable

34、e emission excessive increase of temperature for the nominal current, bringing the conductor to a temperature RT, and that for an overload current bringing the conductor to a temperature (Max RT + 5 C or Max RT + 10 C) there is neither ignition nor disappearance of non conductive materials. The test
35、 shall be performed with a current generator in DC or AC (400 Hz to 800 Hz RMS). The test shall be performed on sizes as defined in the concerned specification or product standard. The temperatures shall be determined by measuring the variation of the voltage drop in the central part of the cable (2
36、/3 of the useful length maximum) between the voltage application points. ( )20 201 0,004 20URUR=+when Ta= 20 C The current injection shall respect the curve shown in Figure 3.

38、ure 3. At In: no visible smoke or smell or appreciable change of colour (see Note); T shall be inferior to the value specified in product standard. At I1: no visible deterioration of materials (peeling, cracking) no spontaneous combustion and no visible smoke; T1shall be inferior to the value specif
39、ied in product standard. NOTE “Appreciable colour change” is to be defined as the original colour is still recognizable.
