New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard which is identical with ISO 12619-4 : 2016 Road vehicles - Compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blends fuel system components - Part 4: Check valve’ issued by International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards on recommendation of the Automotive Vehicles Running on Non-conventional Energy Sources Sectional Committee and approval of the Transport Engineering Division Council.

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.
