Doc No.: PGD 35(13470) IS ISO/TR 17243-1 : 2014 Machine Tools, Machine Tool Elements and Holding Devices Sectional Committee, PGD 35 NATIONAL FOREWORD This Indian Standard (Part 1) which is identical with ISO/TR 17243-1:2014 Machine tool spindles Evaluation of machine tool spindle vibrations by measurements on spindle housing Part 1: Spindles with rolling element bearings and integral drives operating at speeds between 600 min -1 and 30 000 min -1 issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Machine Tools, Machine Tool Elements and Holding Devices Sectional Committee, PGD 35 and approval of the Production and General Engineering Division Council. Other parts in this series are: Part 2 Direct driven spindles and belt driven spindles with rolling element bearings operating at speeds between 600 min 1 and 30 000 min 1 The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following: a) Wherever the words International Standard appear referring to this standard, they should be read as Indian Standard. b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker. In this adopted standard, reference appears to certain International Standards for which Indian Standards also exist. The corresponding Indian Standards, which are to be substituted in their respective places, are listed below along with their degree of equivalence for the editions indicated: International Standard Corresponding Indian Standard Degree of Equivalence ISO 1925 Mechanical vibration Balancing Vocabulary ISO 1940-1 Mechanical vibration Balance quality requirements for rotors in a constant (rigid) state Part 1: Specification and verification of balance tolerances ISO 2041 Mechanical vibration, shock and condition monitoring Vocabulary IS/IS0 1925:2001 Mechanical Vibration Balancing Vocabulary IS/ISO 21940-11 : 2016 Mechanical Vibration Rotor Balancing Part 11 Procedures and Tolerances for Rotors with Rigid Behavior IS/ISO 2041 : 2009 Mechanical Vibration, Shock And Condition Monitoring Vocabulary 1925:2001 21940-11 : 2016 2041:2009
