Mechanical vibration. Rotor balancing - Description and evaluation of balancing machines Ingestion-build-47182 BS EN IEC 60934 states1 Scope This part of ISO 21940 specifies requirements for evaluating the performance of machines for balancing rotating components by the following tests: a) test for minimum achievable residual unbalance, Umar test; b) test for unbalance reduction ratio, URR test; c) test for couple unbalance interference on single plane machines; d) compensator test. These tests are performed during acceptance of a balancing machine and also later, on a periodic
