After enquiries and votes carried out in accordance with the rules of this Association, this Standard has rece
7、ived the approval of the National Associations and the Official Services of the member countries of ASD, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 20
8、09, and conflicting national standards shall be withdrawn at the latest by August 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights

EN 4532:2009 (E) 4 1 Scope This standard covers two cable types, Type A and Type B. Type A, jacketed fibre, is intended for printed circuit b
11、oard inter-connection applications inside equipment. Type B, single core, is intended for general airframe and equipment inter-connection cable suitable for installation in all aircraft locations, with exception of power plant compartments. These cables are particularly suitable for use in military
12、aircraft as well as for general civil aircraft applications. 2 Normative references The following referenced documents are indispensable for the application of this document.
