Mechanical ambient conditions
The following table shows the mechanical ambient conditions in the form of sinusoidal
vibrations.
Table 9-10 Mechanical ambient conditions
Frequency range in Hz
5 ≤ f ≤ 8.4 Amplitude 3.5 mm
8.4 ≤ f ≤ 150 constant acceleration 9.8 m/s

Reduction of vibration
If the described components are subject to big shock or vibration, appropriate measures must
be taken to reduce the acceleration or the amplitude.
We recommend mounting the described components on damping materials (rubber-metal anti-
vibration mountings, for example).
Tests of mechanical ambient conditions
The following table provides important information with respect to the type and scope of the
tests of mechanical ambient conditions.
