9、om IHS-,-,-Page 3 prEN 4056-001: 2002 I Scope This standard specifies the characteristics, test methods, qualification and acceptance conditions of plastic cable ties, used for the bundling, fixing andlor marking of cable harnesses in aircraft. The cable ties should be installedwith a qualified appl
10、ication tool, which controls the application force thus avoiding damage tothe cable insulation. It defines the aerospace requirements not specified in EN 501 46. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normat
11、ive references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated refere
