IS/ISO 22109 : 2020 Industrial Valves-Gearbox for Valves

New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard which is identical with ISO 22109 : 2020 ‘Industrial valves — Gearbox for valves’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Chemical Engineering Plant and Related Equipment Sectional Committee and approval of the Mechanical Engineering Division Council.

The text of ISO (IEC) 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.
