EN 4681-001:2017 (E) 4 1 Scope This European Standard specifies the characteristics, test methods, qualification and acceptance conditions of single and multicore electric cables for general purpose with conductors in aluminium or copper-clad aluminium, intended for installation in aircraft electrical systems. The insulation of these cables is designed to withstand aircraft voltages at a frequency not exceeding 2 000 Hz. Unless specified by individual product standards the maximum demonstrated voltage of rating of these cables is ac 115 V rms phase to neutral and 200 V rms phase to phase and 28 V d.c. They are divided into types, the characteristics of which are given in the product standards. Unless otherwise specified in the product standard, the tests defined in this standard apply. 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 (including any amendments) applies.

EN 4681-001:2017 (E) 5 3 Terms, definitions, symbols and abbreviations For the purposes of this standard, the terms, definitions, symbols and abbreviations given in EN 3475-100 or TR 4684 apply. 4 Materials and construction of cables 4.1 Conductors They shall conform to EN 4651 or EN 3719 unless otherwise specified. 4.2 Finished cables The insulation material shall present a uniform circular cross-section throughout the length of the cable. Covering over the insulation shall be treated and applied in such a manner that the cables present a smooth appearance and are able to accept marking. All materials used shall have no corrosive effect upon the conductors and shall not be susceptible to attack by mould or other micro-organisms. 5 Required characteristics The characteristics of the cables, tested according to the methods described hereafter shall comply with the values given in the product standard. 6 Tests methods See Table 1a for single core cables and Table 1b for multicore cables without jackets.
