ICS 43.060.40

TED 26

NATIONAL FOREWORD

This Indian Standard which is identical to ISO 12614-19 : 2021 'Road vehicles - Liquefied natural gas (LNG) fuel system components - Part 19: Automatic valve' issued by International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Automotive Vehicles Running on Non-Conventional Energy Sources Sectional Committee and approval of the Transport Engineering Division Council.

This standard is one of the series of ISO standards published on liquefied natural gas (LNG) fuel system components. Other standards in this series are:

Part 1 General requirements and definitions

Part 2 Performance and general test methods

Part 3 Check valve

Part 4 Manual valve

Part 5 Tank pressure gauge

Part 7 Pressure relief valve (PRV)

Part 8 Excess flow valve

Part 9 Gas-tight housing and ventilation hose

Part 10 Rigid fuel line in stainless steel

Part 11 Fittings

Part 12 Rigid fuel line in copper and its alloys

Part 13 Tank pressure control regulator

Part 14 Differential pressure fuel content gauge

Part 15 Capacitance fuel content gauge

Part 16 Heat exchanger-vaporizer

Part 17 Natural gas detector

Part 18 Gas temperature sensor

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'; and

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.
