ISO 8821 Mechanical vibration - Balancing - Shaft and fitment key convention




Abstract:
Is intended to provide compatibility of all balanced components so that when they are assembled they will meet the overall balance and/or vibration tolerance levels for that assembly

ISO 10814 Mechanical vibration -- Susceptibility and sensitivity of machines to unbalance





Abstract:
Gives methods for determining machine vibration sensitivity to unbalance and provides evaluation guidelines. Makes recommendations on how to apply the numerical sensitivity values in some particular cases.

ISO 1940 Part 1,2: Mechanical vibration - Balance quality requirements for rotors in a constant (rigid) state




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.
