ISO Balancing Standards

This International Standard establishes, in English and in French, a vocabulary on balancing. An alphabetical index is provided for each of the two languages. A general vocabulary on vibration and shock is given in ISO 2041. NOTE Terms in boldface in the definitions are themselves...

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...

This document provides a general background to balancing technology, as used in the ISO 21940 series, and directs the reader to the appropriate parts of the series that include vocabulary, balancing procedures and tolerances, balancing machines and machine design for...

This document defines terms on balancing. It complements ISO 2041, which is a general vocabulary on mechanical vibration and shock.

This International Standard gives requirements for the evaluation of the performance and characteristics of machines for balancing rotating components. It stresses the importance attached to the form in which the balancing machine characteristics should be specified by the...

ISO 21940-2:2017 defines terms on balancing. It complements ISO 2041, which is a general vocabulary on mechanical vibration and shock.

This document specifies requirements and provides calculations for the permissible static and dynamic residual unbalances of rotating single tools and tool systems. It is based on the guideline that unbalance related centrifugal forces induced by the rotational speed do not harm the spindle...

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...

This document establishes procedures and unbalance tolerances for balancing rotors with rigid behaviour. It specifies a) the magnitude of the permissible residual unbalance, b) the necessary number of correction planes, c) the allocation of the permissible residual unbalance to the tolerance...

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...

This part of ISO 21940 specifies one convention for balancing the individual components (shaft and fitments) of a keyed rotor assembly. This provides compatibility of all balanced components so that when they have been assembled the overall balance tolerance and/or vibration...

ISO 21940-11:2016 establishes procedures and unbalance tolerances for balancing rotors with rigid behaviour. It specifies a) the magnitude of the permissible residual unbalance, b) the necessary number of correction planes, c) the allocation of the permissible residual unbalance to...
