The use of Weighting Standard
Example:
Suppose we have configured:
• Standard 18, DIN 4150-3, with Zeile 1 (selected according to
table in Appendix H).
• Threshold level = 20 mm/s.
A graph from the standard DIN 4150-3 Zeile 1 is shown in Figure I1:
Figure I1. Standard DIN 4150-3 with
the limits for Zeile 1 - 3 (Line 1 - 3)
From Appendix H we can see that the reference frequency range is:
f < 10 Hz.
In this example we study Zeile 1 (Line 1), which for example allows
• 2.0 times higher velocities at 50 Hz compared to
frequencies < 10 Hz
• 2.5 times higher velocities at 100 Hz compared to
frequencies < 10 Hz
