9、ed without license from IHS-,-,-Page 3 prEN 2084: 2000 1 Scope This standard specifies the characteristics, test methods, qualification and acceptance conditions of single- core electric cables for general purpose with conductors in copper or copper alloy, intended for installation in aircraft circu
10、its. 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 O00 Hz. They are divided into types, the characteristics of which are given in the product standards. Unless otherwise specified in the product standard, the tests de
11、fined in this standard apply. 2 Normative references This European Standard incorporates by dated or undated reference provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subse
