1.1 This part of IEC 62282 covers safety requirements for fuel cell power systems intended to be used in electrically powered industrial trucks.
1.2 This standard is limited to electrically powered industrial trucks and is applicable to material-handling equipment, e.g. forklifts.
1.3 This standard applies to gaseous hydrogen-fuelled fuel cell power systems and direct methanol fuel cell power systems for electrically powered industrial trucks.
1.4 The following fuels are considered within the scope of this standard:
-
gaseous hydrogen
-
methanol.
1.5 This standard covers the fuel cell power system as defined in 3.8 and Figure 1.
1.6 This standard applies to d.c. type fuel cell power systems, with a rated output voltage not exceeding 150 V d.c. for indoor and outdoor use.
1.7 This standard covers fuel cell power systems whose fuel source container is permanently attached to either the industrial truck or the fuel cell power system.
1.8 The following are not included in the scope of this standard:
-
detachable type fuel source containers;
-
hybrid trucks that include an internal combustion engine;
-
reformer-equipped fuel cell power systems;
-
fuel cell power systems intended for operation in potentially explosive atmospheres;
-
fuel storage systems using liquid hydrogen.
