2、2.BSI as a member of CEN, is obliged to publish EN 4681-001:2012 as a British Standard. However, attention is drawn to the fact that during the development of this European Standard, the UK committee voted against its approval as a European Standard.In the opinion of the committee, the 600 V rms AC
3、rating is not justified by the tests required by this standard, as different test conditions require the use of different voltages. For example, the arc track test which is mentioned in table 1 is carried out using either a 115 V or 230 V, according to BS EN 3475-603:2011, and so is the need for a c
4、orona test on cables used in non-pressurized zones on AC systems above 115 V phase to neutral.The UK participation in its preparation was entrusted to Technical Committee ACE/6, Aerospace avionic electrical and fibre optic technology.A list of organizations represented on this committee can be obtai

BS EN 4681-001:2012EN 4681-001:2012 (E) 4 1 Scope This European Standard specifies the characteristics, test methods, qualification and acceptance conditions of single-core electric cables for general purpose with conductors in a
20、luminium or copper-clad aluminium, intended for installation in aircraft electrical systems. The insulation of these cables is designed to withstand a maximum service voltage of 600 V r.m.s. at a frequency not exceeding 2 000 Hz. They are divided into types, the characteristics of which are given in
21、 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.
