ISO 1940-1:2003 gives specifications for rotors in a constant (rigid)
state. It specifies balance tolerances, the necessary number of
correction planes, and methods for verifying the residual unbalance.
Recommendations are also given concerning the balance quality
requirements for rotors in a constant (rigid) state, according to their
machinery type and maximum service speed. These recommendations are
based on worldwide experience.
ISO 1940-1:2003 is also intended to facilitate the relationship between
the manufacturer and user of rotating machines, by stating acceptance
criteria for the verification of residual unbalances.
Detailed consideration of errors associated with balancing and verification of residual unbalance are given in ISO 1940-2.
ISO 1940-1:2003 does not cover rotors in a flexible state. The balance
quality requirements for rotors in a flexible state are covered by ISO
11342.

ISO 4863 Resilient shaft couplings - Information to be supplied by users and manufacturers
Abstract:Gives specifications in order to facilitate
communication and understanding. Does not apply to rigid flange or
sleeve couplings; torsionally stiff couplings for alignment purposes,
all types of slip couplings. Does not give dimensional requirements for
either shafts or couplings.
