Description / Abstract:
This part of ISO 21940 specifies requirements for enclosures and
other protective measures used to minimize mechanical hazards
produced by the rotor in the unbalance measuring station of
centrifugal (rotational) balancing machines. The hazards are
associated with the operation of balancing machines under a variety
of rotor and balancing conditions. This part of ISO 21940 defines
different classes of protection that enclosures and other
protective measures provide and describes the limits of
applicability for each class of protection.
Devices for adjusting the mass distribution of a rotor and
devices to transfer the rotor are not covered by this part of ISO
21940, even if they are combined with the measuring station.
Special enclosure features, such as noise reduction, windage
reduction or vacuum (which may be required to spin bladed rotors at
balancing speed), are not covered by this part of ISO 21940.
