Fuel cell road vehicles – Safety specifications – Protection against hydrogen hazards for vehicles fuelled with compressed hydrogen
Standard specifies the essential requirements for fuel cell vehicles (FCV) with respect to the protection of persons and the environment inside and outside the vehicle against hydrogen-related hazards. It applies only to such FCV where compressed hydrogen is used as fuel for the fuel cell system.
This standard does not apply to manufacturing, maintenance, and repair.
The requirements of this standard address both normal operating (fault-free) and single-fault conditions of the vehicles.
The standard was prepared by the P3652 Hydrogen Standards Committee and is identical to and has been reproduced from ISO 23273:2013, Fuel cell road vehicles − Safety specifications − Protection against hydrogen hazards for vehicles fuelled with compressed hydrogen.
