uncertainty by the coverage factor k = 2. The value of the measurand lies within the assigned range of values with a probability of 95%.
(3)
Maximum peak of impact should be less or equal to 50 [g],
(4)
If any, the maximum duration in at 38 [g] should be less or equal to 7 [ms],
(5)
If any, the maximum duration in at 20 [g]
should be less or equal to 25 [ms].
(6)
The test should be done twice, and the 2nd test the maximum peak should not differe more than 20% from the first test, maximum peak.
