After inquiries and votes carried out in accordance with the rules of ASD-STAN defined in ASD
14、-STANs General Process Manual, this standard has received approval for Publication. prEN 4612-007:2018 (E) 3 1 Scope This standard specifies the characteristics of UV laser printable jacket, silver plated copper conductor, electrical cables Crosslinked Ethylene Tetra Fluoro Ethylene co-polymer (XLET
15、FE) family for use in the on-board electrical systems of aircraft operating at temperatures between - 65 C and 150 C, operating at voltages not exceeding 600 V rms at sea level. This insulation system has been used in aerospace applications using 115 V (phase-to-neutral) 400 Hz ac and 28 Vdc. Verifi
16、cation of the suitability of cables for use in other electrical systems is the responsibility of the user. These jacketed cables are suitable for airframe use without additional protection when the jacket is present. When the jacket is stripped back the cores may need additional protection. In case
17、of conflict between this standard and other referenced documents the requirements of this standard shall take precedence. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
