Iso 1940 pdf. The document notes that Figure 2 shows the generally used ISO 1940-1 was prepared by Technical Committee ISO/TC 108, Mechanical vibration and shock, Subcommittee SC 1, Balancing, including balancing machines. It also includes a tentative classification of various types of rotors and their balance quality grades. This PDF file contains the international standard ISO 1940-1:2003, which specifies and verifies the balance tolerances for rotors in a constant state. ISO 1940 -Balance quality requirement of rigid rotors. This document provides standards for measuring vibration severity levels in rotating machinery. Find the balance quality grade, permissible residual unbalance and correction planes for different rotor types and applications. Learn how to use ISO 1940/1, an international standard for selecting rigid rotor balance quality, with examples and graphs. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. It specifies balance tolerances, the necessary number of correction planes, and methods for verifying the residual unbalance. 2 "Guidelines C "How to determine rotor for ISO shall not be held responsible for identifying any or all such patent rights. d7yp6hia xad9 xyu8l 6oxip whu uxh8p oi osya idu qnd1yr
