Scope

PURPOSE AND SCOPE. --- Establishment of the installation requirements for hydrogen generating equipment, hydrogen utilizing equipment, hydrogen dispensing equipment, hydrogen storage containers, hydrogen piping systems and their related accessories.

This code applies to all gaseous hydrogen and liquid hydrogen applications except the following:

--- The use of hydrogen in petroleum refineries and chemical plants as feedstock and directly in-process production;
--- Industrial hydrogen installations that produce and/or use on a continuous basis mass flow rates that are in excess of 21 kg/h;
 
Notes. --- 

1  The limiting size applies to a continuous production and use of hydrogen, but not to the filling/transfer peak rate.

2  A cubic metre of hydrogen at 20 °C and 101,325 kPa equals to 0,083 8 kg of hydrogen (example: 21 kg/h is equivalent to 250 m³/h at 20 °C and 101,325 kPa).

--- Industrial installations that produce hydrogen as a by-product;
--- Hydrogen installations that produce liquid hydrogen;
--- Hydrogen installations onboard vehicles, boats, airplanes and space vehicles;
--- Micro fuel cell systems for electronic equipment;
--- Hydrogen transportation including the hydrogen utility pipeline distribution and transmission pipelines;
--- Hydrogen marine or pipeline terminals.
