Testing methods
2.1
Visual checks
After each direction the specimens were subjected to a visual check.
2.2
Random Vibration test, (long-term test)
The vibration test was conducted in accordance with the standard DIN EN 61373, Category
1, Class B. The category and class were specified by the customer.
The test parameters were defined as follows:
excitation mode:
frequency range:
power density:
effective acceleration:
test duration:
total test duration:
test temperature:
Random
5–150 Hz
Longitudinal, Transversal, Vertical
5–20 Hz
0.964 (m/s2)2/Hz
20–150 Hz -6 dB/octave
5.72 m/s2 (rms)
approx 3 x 5 h
approx 15 h (effective vibration time)
room temperature
Diagrams 1 at pages 6 shows exemplarily the regulating channel’s excitation during the
vibration test.
2.3
Mechanical shock test
The shock test was conducted in accordance with the standard DIN EN 61373, Category 1,
Class B. The category and class were specified by the customer.
The test parameters were defined as follows:
shock pulse:
shock duration and amplitude:
test directions:
number of shocks:
test temperature:
Halbsinus
30 ms bei 50m/s²
6 Richtungen
18 (3 x 6 directions)
room temperature
Diagrams 2 to 3 at pages 7 to 8 show the regulating channel’s shock excitation in the positive
and negative directions.
The following pictures show the test specimens undergoing the vibration and shock tests.

Test procedure
The vibration and shock tests were conducted in the following order:
1. long-term vibration test, first horizontal axis
2. positive and negative shock test, first horizontal axis
3. long-term vibration test, second horizontal axis
4. positive and negative shock test, second horizontal axis
5. long-term vibration test, vertical axis
6. positive and negative shock test, vertical axis

Result
The visual inspection of the specimens after testing could not detect any cracks, chipping,
deformation, abrasion, or other mechanical damage.
The specimens did not unlock during the tests.
