This consumer safety standard covers micro fuel cell power systems and fuel cartridges that are wearable or easily carried by hand, providing d.c. (direct current) outputs that do not exceed 60 V d.c. and power outputs that do not exceed 240 VA.
Portable fuel cell power systems that provide output levels that exceed these electrical limits are covered by IEC 62282-5-1.
Externally accessible circuitry is therefore considered to be ES1 energy source as defined in IEC 62368-1, and as limited power source if further compliance with Annex Q of IEC 62368-1 is demonstrated. Micro fuel cell power systems that have internal circuitry exceeding 60 V d.c. or 240 VA should be appropriately evaluated in accordance with the separate criteria of IEC 62368-1.
This consumer safety standard covers micro fuel cell power systems and fuel cartridges. This standard establishes requirements for micro fuel cell power systems and fuel cartridges to ensure a reasonable degree of safety for normal use, reasonably foreseeable misuse, and cargo and consumer transportation and storage of such items. The fuel cartridges covered by this standard are not intended to be refilled by the consumer. Fuel cartridges refilled by the manufacturer or by trained technicians shall meet all requirements of this standard.
These products are not intended for use in hazardous areas as defined by IEV 426-03-01.
Under development. Approved for Final Draft International Standard.
