NATIONAL FOREWORD

This Indian Standard which is identical with ISO 19490 : 2017 ‘Dentistry - Sinus membrane elevator’ issued by the International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards on recommendation of the Dentistry Sectional Committee and after approval of the Medical Equipment and Hospital Planning Division Council.

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