3、: Allgemeines This “Aerospace Series“ frestandard has been drawn up under the responsibility of AECMA-STAN (The European Association of Aerospace Industries - Standardization). It is published for the needs of the European Aerospace Industry. It has been technically approved by the experts of the co
4、ncerned Domain following member comments. Subsequent to the publication of this frestandard, the technical content shall not be changed to an extent that interchangeabilify is affected, physically or functionally, without re-identification of the standard. After examination and review by users and f
5、ormal agreement of AECMA-STAN, it will be submitted as a draft European Standard (prEN) to CEN (European Committee for Standardization) for formal vote and transformation to full European Standard (EN). The CEN national members have then to implement the EN at national level by giving the EN the sta
6、tus of a national standard and by withdrawing any national standards conflicting with the EN. Page 2 prEN 461 1-002:2004 Foreword This standard was reviewed by the Domain Technical Coordinator of AECMA-STANS Electrical Domain. After inquiries and votes carried out in accordance with the rules of AEC

29、l be in accordance with EN 2084. As the designation, required for orders, is generally too long, for use in electrical drawings a shorter designation (without colour information) is given in TR 6058. Example: Designation: EN 461 1 -004A006P Cross reference: XLETFE 20 This shorter designation is used
30、 for identification and marking as in the following example: . i I Size code I ? I &b I Manufacturer country code I Manufacturer code Year of manufacturing EN zz C 20 ? & 55 For multicore cable with jacket, the marking shall be optional on core(s) and mandatory on jacket. For multicore cable without jacket, each core shall be marked with his own designation. The cables (single core or jacketed cable) shall be capable of being printed with user-applied UV laser markings according to EN 3838. Aggressive marking techniques are not permitted. 7 See EN 2084.
