Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Second Revision) which is identical with ISO 9168 : 2009 ‘Dentistry - Hose connectors for air driven dental handpieces’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Dentistry Sectional Committee and approval of the Medical Equipment and Hospital Planning Division Council.

This standard was originally published in 1989 and subsequently revised in 2009. Original version of this standard was identical with ISO 9168 : 1988 ‘Dental handpieces - Hose connectors’. Its first revision was identical with ISO 9168 : 1991. The second revision of this standard has been undertaken to align it with the latest version of ISO 9168 : 2009.

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.
