New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard which is identical to ISO 16827 : 2012 ‘Non-destructive testing - Ultrasonic testing - Characterization and sizing of discontinuities’ issued by the International Organization for Standardization (ISO) was adopted by Bureau of Indian Standards on the recommendation of the Non-Destructive Testing Sectional Committee and approval of the Metallurgical Engineering Division Council.

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