NATIONAL FOREWORD

This Indian Standard (Part 2) (First Revision) which is identical with ISO 7626-2 : 2015 ‘Mechanical vibration and shock - Experimental determination of mechanical mobility - Part 2: Measurements using single-point translation excitation with an attached vibration exciter’ issued by 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 in 1999 and was based on ISO 7626-2 : 1990 ‘Vibration and shock - Experimental determination of mechanical mobility - Part 2: Measurements using single-point translation excitation with an attached vibration exciter’. The first revision of this standard has been undertaken to align it with the latest version of ISO 7626-2 : 2015.

This Indian Standard is published in three parts. Other parts in this series are:

Part 1 Basic terms and definitions, ad transducer specifications

Part 3 Measurements using impact excitation with an exciter which is not attached to the structure

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