IS/ISO 7919 : Part 3 : 2009 : Mechanical Vibration - Evaluation of Machine Vibration by Measurements on Rotating Shafts Part 3 Coupled Industrial Machines

NATIONAL FOREWORD

This Indian Standard (Part 3) which is identical with ISO 7919-3 : 2009 ‘Mechanical vibration — Evaluation of machine vibration by measurements on rotating shafts — Part 3: Coupled industrial machines’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Mechanical Vibration and Shock Sectional Committee and approval of the Mechanical Engineering Division Council.

This standard was originally published as IS 14773 (Part 3) : 2000 ‘Mechanical vibration of nonreciprocating machines – Measurements on rotating shafts and evaluation criteria: Part 3 Coupled industrial machine’ which was identical with ISO 7919- 3 : 1996. As ISO 7919 has been technically revised in 2009 the committee has decided to adopt this standard in a single number as IS/ISO 7919-3 : 2009 by superseding IS 14773 (Part 3) : 2000 and after the publication of this standard IS 14773 (Part 3) : 2000 shall be treated as withdrawn.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminology and 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.
