IS 19026 : Part 8 : 2023/ISO 12614-8 : 2021 Road Vehicles - Liquefied Natural Gas (LNG) Fuel System Components - Part 8 Excess Flow Valve

ICS: 43.060.40

TED 26

NATIONAL FOREWORD

This Indian Standard (Part 8) which is identical to ISO 12614-8 : 2021 'Road vehicles - Liquefied natural gas (LNG) fuel system components - Part 8: Excess flow 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 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

 Part 19 Automatic valve

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.
