NATIONAL FOREWORD

This Indian Standard (Part 1) (First Revision) which is identical with ISO 7626-1 : 2011 ‘Mechanical vibration and shock - Experimental determination of mechanical mobility Part 1: Basic terms and definitions, and transducer specifications’ 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 first published in 1999. The first revision of this standard has been taken up to harmonize it with the latest version of ISO 7626-1 : 2011.

Under the general title ‘Mechanical vibration and shock - Experimental determination of mechanical mobility the standard is in three parts. Other parts are as follows:

Part 2 Measurements using single-point translation excitation with an attached vibration exciter

Part 5 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 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.
