ISO 21940-13:2012

Mechanical vibration - Rotor balancing - Part 13 : criteria and safeguards for the in-situ balancing of medium and large rotors

ISO 21940-13:2012 specifies procedures to be adopted when balancing medium and large rotors installed in their own bearings on site. It addresses the conditions under which it is appropriate to undertake in-situ balancing, the instrumentation required, the safety implications and the requirements for reporting and maintaining records.

ISO 21940-13:2012 can be used as a basis for a contract to undertake in-situ balancing.

It does not provide guidance on the methods used to calculate the correction masses from measured vibration data.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.
