ISO 7137, Aircraft Environmental conditions and test procedures for airborne equipment EN 3841-100, Aerospace series Circuit breakers Test methods Part 100: General 3 Method 3.1 Mounting The circuit breakers shall be mounted on the shock table according to 4.2 and 4.3 of EN 3841-100. The means

19、of mounting shall be designed so as to transmit the pulses without absorption or natural resonance. The electrical connection shall be made with the cables of the sections specified in EN 3841-100, Table 1. The connection cables shall be attached to the shock table approximately 100 mm from the term

20、inals. The circuit breakers and the cables shall be mounted with the torque indicated in the product standard. 3.2 Procedure The circuit breakers shall be subjected to the mechanical shocks test according to ISO 7137, test procedure 2.1. Three shocks shall be applied in each direction and for every

21、switch setting: in the closed position at 90 % of current rating; in the open position. The acceleration peak value (half sine-wave from of 11 ms duration) is specified in the technical specification. During the test, it shall be established that the contacts do not close for a period 10 s (circuit

22、breakers in the open position) or open for a period 10 s (circuit breakers in the closed position). 4 Requirement Requirements in accordance with technical specification and product standard. blankBS EN 3841-507:2004 BSI 389 Chiswick High Road London W4 4AL BSI British Standards Institution BSI is t
