27、 The acceleration gradient in the specimen shall not exceed10% of the steady-state specified value. If the dimensions of the specimen are smaller than100mm, the acceleration applied at any point on the specimen shall not deviate by 10% of the steady-state specified value; otherwise the acceleration

29、 specimen shall be submitted to the acceleration for5min in each of both directions of the three tri-rectangular axes so that the total duration of the test is30min. During the test, a check of the electrical discontinuity of the contacts in the microsecond range (test EN2591-204) shall be carried o
