16、magnetism 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing connectors within the scope of technical committee 48. It may also be used for similar devices when specified in a detail specification. The object of this standard is to detail a stan

17、dard method to measure the residual magnetism of a connector after exposure to a specified magnetic field. 2 Preparation of the specimen The connector shall be prepared and mounted in a fixture as required by the detail specification. 3 Test method A magnetometer with a suitable probe shall be place

18、d horizontally on a non-magnetic support with the probe positioned as far away from the measuring instrument as allowed by the connecting cord. The measuring instrument shall be set to the appropriate scale and the probe oriented so as to read “0“. The specimen shall be exposed to a magnetic field o

19、f approximately 0,5 T (5 000 G) three times. NOTE The specimen should not touch the polar parts of the magnet. Immediately after magnetization, the specimen shall be placed at a distance not exceeding 3 mm from the probe, without touching the probe. The specimen shall be oriented so as to obtain a m

20、aximum reading on the measuring instrument. 4 Requirements The value measured shall not exceed the maximum value specified by the detail specification. 5 Details to be specified When this test is required by the detail specification, the following details shall be specified: a) accessories to be fit

21、ted on the specimen; b) maximum value of the residual magnetism; c) any deviation from the standard test method. _ BS EN 60512-24-1:2012This page deliberately left blankThis page deliberately left blankBSI is the independent national body responsible for preparing British Standards and other standar
