34. BS 7385 (+ Frequency)
Evaluation and measurement for vibration in buildings - Part 2: Guide to
damage levels from ground-borne vibration.
Level, frequency ranges: 25 mm/s, 1-300 Hz
Max resolution in presentation: 0.005 mm/s and 3 significant digits.
Threshold range 0.04 – 22 mm/s.

35. AS 2187.2-2006 (+ Frequency)
Explosives - Storage, transport and use - Use of explosives
Level, frequency ranges: 250 mm/s, 2-250 Hz
Max resolution in presentation: 0.05 mm/s and 3 significant digits.
Threshold range 0.4 – 220 mm/s.
Transient file resolution: ~0.01 mm/s.
36. Particle displacement
Level, frequency ranges: 1500 µm, 10-60 Hz
Max resolution in presentation: 1 µm and 3 significant digits.
Threshold range 10-1300 µm.
Transient file resolution: ~0.2 µm.
Note! The stated range/resolution in “displacement” is only valid at 16Hz
and below because sensor element measures velocity. At higher
frequencies the range/resolution is scaled down.
