NATIONAL FOREWORD

This Indian Standard (Part 2) which is identical with ISO 10816-2 : 2009 ‘Mechanical vibration — Evaluation of machine vibration by measurements on non-rotating parts — 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 3 600 r/min’ 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 supersedes IS/ISO 10816-2 : 2001 ‘Mechanical vibration — Evaluation of machine vibration by measurements on non-rotating parts : Part 2 Land-based steam turbines and generators in excess of 50 MW with normal operating speed of 1 5 r/min, 1 800 r/min, 3 000 r/min and 3 600 r/min’.

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

Part 1 General guidance

Part 3 Industrial machines with the nominal power above 15 kW and nominal speeds between 120 r/min and 1 500 r/min when measured in situ

Part 4 Gas turbines driven sets 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.

Part 7 Rotodynamic pumps for industrial applications, including measurements on rotating shafts

Part 8 Reciprocating compressor systems

Part 21 Horizontal axis wind turbines with gearbox

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.
