NATIONAL FOREWORD

This Indian Standard (Part 5) which is identical to ISO 14839-5 : 2022 'Mechanical vibration - Vibration of rotating machinery equipped with active magnetic bearings - Part 5: Touch-down bearings' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Bearings Sectional Committee and after approval of the Production and General Engineering Division Council.

This standard is published in five parts. Other parts in this series are:

Part 1 Vocabulary

Part 2 Evaluation of vibration

Part 3 Evaluation of stability margin

Part 4 Technical guidelines

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'; and

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.
