NATIONAL FOREWORD

This Indian Standard (Part 3) (First Revision) which is identical with ISO 10816-3 : 2009 ‘Mechanical vibration — Evaluation of machine vibration by measurements on non-rotating Parts : Part 3 Industrial machines with nominal power above 15 kW and nominal speeds between 120 r/min and 15 000 r/min when measured in situ’ 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.

The Indian Standard supersedes IS 14817 (Part 3) : 2004/ISO 10816-3 : 1998 ‘Mechanical vibration - Evaluation of machine vibration by measurements on non-rotating parts : Part 3 Industrial machines with nominal power above 15 kW and nominal speeds between 120 r/min and 15000 r/min when measured in situ’.

Under the general title ‘Mechanical vibration - Evaluation of machine vibration by measurements on non-rotating parts’, the standard is in six parts, other parts are following:

Part 1 General guidelines

Part 2 Land-based steam turbines and generators in excess of 50 MW with normal operating speeds of 1 500 r/min, 1 800 r/min, 3 000 r/min and 3600 r/min

Part 4 Gas turbines driven set excluding aircraft derivatives

Part 5 Machine sets in hydraulic power generating pumping and pumping plants

Part 6 Reciprocating machines with the power rating above 100 kW.

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.
