The ISO10816-3 Machine Vibration Standard
Industrial machines covered by the ISO10816-3 standard include :-
Steam turbines with nominal power less than 50MW
Steam turbines with nominal power above 50MW with speeds less
than 1500rpm or above 3600rpm (ie. excludes machines included
in ISO10816-2
Rotating compressors
Industry gas turbines with nominal power less than 3MW
Centrifugal, Mixed flow, or Axial flow pumps
Electric Generators excluding Hydro-electric or pump stations
Electrical motors of all types
Blowers or fans
The standard classifies machine groups as in section 2.5 and defines
vibration levels for each group, shown in the chart on page 9, as follows:-
Green – levels expected for a new machine.
Yellow - levels considered as acceptable for long periods.
Amber - levels not acceptable for long periods.
Red – levels likely to cause machine damage.
It further classifies machines as being either rigid or flexible mounted with the
flexible mounted machines being allowed higher vibration levels. The meter
indicates a tick box for levels in the green and yellow sections and uses the
lower limit for the amber sections and the red sections in its vibration
assessment.
