FOREWORD
This Indian Standard was adopted”bytheBureau ofIndian Standards, after the draft finalized bytheAutomotive
VehiclesRunning onNon-conventional Energy Sources Sectional Commitlee hadbeen approved bytheTransport
Engineering Division Council.
Inthe formulation ofthis standard considerable assistance has been derived from the following standards:
AIS 024 (Amd 4 to version 3)— Safety and procedural requirements for type approval of CNG operated
vehicles
AIS-028 (Version 3)— Code ofpractice for use ofCNG fhel ininternal combustion engine vehicles
This standard isone ofthe series ofIndian Standards published onCNG onboard l%elsystem components. Other
standards inthis series are:
