15、2005) has been prepared by the European Association of Aerospace Manufacturers - Standardization (AECMA-STAN). After enquiries and votes carried out in accordance with the rules of this Association, this Standard has re-ceived the approval of the National Associations and the Official Services of th
16、e 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of an identical text or by endorsement, at the latest by May 2006, and conflicting national standards shall be withdrawn at the latest by May
17、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 Regulations, the national standards organi

EN 4057-405:20054 1 Scope This standard specifies the procedure to determine the compass safe distance of cable ties with metallic lock-ing devices. It shall be used together with EN 4057-100. 2 Normative references The following referenced
20、 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 referenced document (including any amendments) applies. EN 4057-100, Aerospace series Cable ties for harnesses Test methods Part
21、 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 Procedure The measurement of the compass safe distance, shall be made in a uniform magnetic field, the horizontal component of whi
22、ch, 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 lines. The cable tie under test shall be placed, with the head closest to the magnetometer, on the East-West line, at a distance
23、 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 half a degree. From readings taken at intervals during this movement, a curve shall be plotted showing compass deviation against
24、 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 coincidental and should be used to establish accurately, the distance at which one degree deviation of the magnetometer is experien
25、ced. 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 Requirements The samples tested shall meet the requirements as specified in the appropriate product standard.
