After enquiries and votes carried out in accordance with the rules of this Association, this Standard has re-ceived the approval of the National Asso

17、ciations and the Official Services of the member countries of AECMA, 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 May 2006, and conflicting national standards

18、shall be withdrawn at the latest by May 2006. 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. According to the CEN/CENELEC Internal Re

21、s with metallic lock-ing devices. It shall be used together with EN 4057-100. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated refer-ences, only the edition cited applies. For undated references, the latest edition of the ref

22、erenced document (including any amendments) applies. EN 4057-100, Aerospace series Cable ties for harnesses Test methods Part 100: General 3 Apparatus A suitable magnetometer shall be a compass, capable of being read to within a fifth of a degree, and possess-ing a corresponding sensitivity. 4 Proce

23、dure The measurement of the compass safe distance, shall be made in a uniform magnetic field, the horizontal component of which, has a value of 0,18 line/cm2+ 10 %. An area shall be marked out with magnetic North-South and East-West lines, and the magnetometer placed at the intersection of these lin

24、es. The cable tie under test shall be placed, with the head closest to the magnetometer, on the East-West line, at a distance from the magnetometer, which gives a deviation of approximately 2. The cable tie is moved outward on the East-West line, until the magnetometer deviation is approximately hal

25、f a degree. From readings taken at intervals during this movement, a curve shall be plotted showing compass deviation against distance. As a check on experimental error, a curve shall also be plotted to correspond with an inward movement of the cable tie. The two curves shall be substantially coinci

26、dental and should be used to establish accurately, the distance at which one degree deviation of the magnetometer is experienced. This distance, measured in millimetres, from the pivot of the compass, to the nearest point on the cable tie, shall be recorded as the compass safe distance. 5 Requiremen

27、ts The samples tested shall meet the requirements as specified in the appropriate product standard.
