NATIONAL FOREWORD

This Indian Standard which is identical with ISO 21289 : 2008 ‘Mechanical vibration and shock ?? Parameters to be specified for the acquisition of vibration data’ 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.

Use of this Standard is recommended to minimize errors and ambiguities in vibration measurement due to inadequate or confusing definition of essential parameters.

The specified parameters provide information to enable a measurement to be conducted and data to be provided, assuming that proper practices and all-applicable sub-specifications have been followed. Proper use of this Standard will improve the quality of databases for vibration condition monitoring and assessment of machines and structures.

It will also facilitate improved comparison of vibration test data conducted by different organizations, using different methods, or over long periods of time.

The text of ISO Standard is to be 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.
