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. The Practical Application of ISO 1940/1. Balance Quality Requirements of Rigid Rotors by D.L. Pete Bernhard. D. L. "Pete" Bernhard has more than 34 years experience in machinery vibration analysis, dynamic balancing and instrumentation, including 28 years with the former IRD Mechanalysis. 13/09/2013 · IS/ISO 1940-1: Mechanical vibration - Balance quality requirements for rotors in a constant Rigid state, Part 1: Specifications and verfication of balance tolerances. 13/09/2013 · In order to promote public education and public safety, equal justice for all, a better informed citizenry, the rule of law, world trade and world peace, this legal document is hereby made available on a noncommercial basis, as it is the right of all humans to know and speak the laws that govern them.
Secondo ISO 1940-1 - Requisiti di qualità del bilanciamento per rotori in uno stato rigido costante, G è una misura della qualità del bilanciamento di un corpo rotante. G è la velocità tangenziale al baricentro in relazione alla velocità rotazionale. G dipende da velocità rotazionale n, massa del corpo m e sbilanciamento U. Balancing requirement according to iso 1940 1. Balancing Requirement According to ISO 1940/1 2. 1. Introduction 1.1 Known as International Standard Organization, ISO 1940/1 – Balance quality requirements for rigid rotors. The International Standards Organization, ISO, published Standard 1940/1 "Balance Quality Requirements of Rigid Rotors," which has been adopted by the American National Standards Institute, ANSI, as S2.19-1975, "Balance Quality Requirements of Rotating Rigid Bodies." It has also been adopted by BRITISH Standards as BS. The ISO 1940 standard defines balance grades for different classes of machinery. Rigid Rotors Only Example: Balance Grade “G2.5” is recommended for Steam Turbines, Machine Tools and Small Electric Armatures. ISO 11342 defines the balance quality requirements for rotors in a flexible state. 09/11/2016 · NOTE In ISO 21940‑14, the assessment of balancing errors is considered in detail. Fundamentals of rotor balancing are contained in ISO 19499 which gives an introduction to balancing. ISO 21940-11:2016 does not cover the balancing of rotors with flexible behaviour.

The main changes are deletion of the terms and definitions which were transferred to ISO 21940-2 and deletion of former Annex F which is a duplication of a part of D.1. It also incorporates the Technical Corrigendum ISO 11342:1998/Cor.1:2000. ISO standards classifies rotor in accordance with their balancing requirements and establishes methods of assessment of residual unbalance. The ISO also shows how criteria for use in the balancing facility. from ISO 1940-1 in terms of permissible residual balance. In conformità alla norma ISO 1940 la precisione di equilibra-tura viene indicata con la lettera G. Il valore di equilibratura G viene espresso in g/mmkg e ´m e si riferisce al numero di giri. Nota: Per un numero di giri pari a 9.500 1/min ed un peso di 1 kg, G2,5 corrisponde ad un disassamento fra l’asse di.
