Machinery Evaluation as per ISO 10816 Guide line: Zone A: Vibration of newly commissioned machines; Zone B: Machines considered acceptable for unrestricted long-term operation Zone C: Machines considered unsatisfactory for long-term continuous operation Zone D: Vibration values normally considered to be sufficient severity to cause damage to the machine
# Refer ISO 13373-1:2002 for General Procedures for vibration measurement.

Measurement Frequency range: 10 Hz to 1000 Hz > 600 RPM* 2 Hz to 1000 Hz > 120 RPM*
* Operating speed of machine

# Refer ISO 10816-1:1995 Standard on Mechanical vibration -- Evaluation of machine vibration by measurements on non-rotating parts. Visit: www.iso.ch
Note ISO 10816 precedes standards ISO 2372 and ISO 3945
