Mechanical environmental conditions
The following table shows the mechanical environmental conditions in the form of sinusoidal
vibrations.
Table 11-3
Frequency range in Hz
5 ≤ f ≤ 8.4
8.4 ≤ f ≤ 150
Reduction of vibration
If the described components are exposed to larger impacts or vibrations, the following applies:
Use suitable measures to ensure that the acceleration or amplitude is always reduced to the
permissible level.
We recommend mounting the described components on damping materials (rubber-metal anti-
vibration mountings, for example).
Tests of mechanical environmental conditions
The following table provides important information with respect to the type and scope of the
tests of environmental mechanical conditions.
