18、 60512, when required by the detail specification, is used for testing connectors for electronic equipment within the scope of IEC technical committee 48. This test may also be used for similar devices when specified in a detail specification. The object of this test is to define a standard test met
19、hod for detecting contact disturbance of electromechanical components under specified dynamic conditions. NOTE Standard conditions of testing are defined in Part 1 of this standard. 2 Mounting of the test specimen The test specimen shall be mounted in accordance with the requirements of the detail s
20、pecification. 3 Method of measurement The contact disturbance shall be determined under dynamic conditions. The duration of the opening of closed contacts and/or the closing of open contacts shall be determined when the component is subjected to bump, shock, vibration, or acceleration tests. The mon
21、itoring of contact disturbance shall be made during the period specified in the relevant test and/or detail specification. The contacts may be monitored individually or in one or more groups as specified in the detail specification. When monitored in groups, closed contacts may be connected in serie
22、s and open contacts may be connected in parallel. NOTE If failure is indicated when testing contacts in groups, it is permitted to test individual contacts subsequently. 4 Requirements The measurement shall be made with d.c. not exceeding 150 mA. The voltage source shall not exceed 10 V. The duratio
23、n of the contact disturbance shall not exceed the value specified in the relevant test and/or detail specification. Preferred values are 1 s, 10 s, 100 s, 1 ms and 10 ms. A closed contact is considered disturbed when the voltage across it exceeds 50 % of the voltage source. An open contact is consid
24、ered disturbed when the voltage across it drops below 50 % of the voltage source. Page3 EN6051225:200360512-2-5 IEC:2003 4 In the case where the contact disturbance is considered to be a change of contact resistance, this change shall be specified in the detail specification 5 Details to be specifie
25、d When this test is required by the detail specification, the following details shall be specified: a) method of mounting and wiring the test specimen; b) monitoring period, if different from that specified in the relevant test method; c) contacts to be monitored and their operating condition; d) li
26、mit of duration of contact disturbance; e) change of contact resistance, if necessary; f) any deviation from the standard test method. _ Page4 EN6051225:2003BS EN 60512-2-5:2003 BSI 389 Chiswick High Road London W4 4AL BSI British Standards Institution BSI is the independent national body responsibl
