IEC PAS 62282-6-1:2006 pdf download Fuel cell technologies – Part 6-1: Micro fuel cell power systems – Safety
Scope
1.1 System boundary
1.1.1 This consumer safety PAS covers fuel cell power systems, power units and fuelcartridges that are wearable or easily carried by hand, providing d.c. outputs that do notexceed 60 V d.c. and power outputs that do not exceed 240 VA. As such, the externallyaccessible circuitry is considered as circuits that are “SELV” as defined in IEC 60950-1, andas limited power circuits if further compliance with IEC 60950-1, 2.5 is demonstratedSystems that have internal systems exceeding 60 V d.c. or 240 VA should be appropriatelyevaluated in accordance with the separate criteria of IEC 60950-1.
1.1.2 This consumer safety PAS covers all fuel cell power systems, units and cartridges.This PAS establishes requirements for all fuel cell power systems, units and cartridges toensure a reasonable degree of safety for normal use, reasonably foreseeable misuse, andconsumer transportation of such items. The cartridges covered by this PAS are not intendedto be refilled by the consumer. Cartridges refilled by the manufacturer or by trainedtechnicians should meet all the requirements of this PAS as unused cartridges.
1.1.3 This PAS also covers compatible and separately transported fuel storage fuelcartridges for supplying fuel to the fuel cell power unit.
1.1.4 Fuel cell power systems that provide output levels that exceed electrical limitsspecified in 1.1.1 are covered by IEC 62282-5
1.1.5 These products are not intended for use in hazardous areas.
1.1.6 Fuels and technologies covered
1.1.6.1 This PAS includes methanol or methanol and water solutions as fuels.
1.1.6.2 This PAS includes equipment designs that include proton exchange membrane(PEM) fuel cell stacks and direct methanol fuel cell stacks (DMFC).
1.1.6.3 This PAS includes requirements for other fuels and the associated systems in theannexes, formatted as deviations or additional requirements to the main body of this PAS.
11.6.4 lt is understood that all fuel cartridges, power units and fuel cell systems shouldcomply with applicable country and local requirements including transportation, child-resistance,and storage, where required.
1.2Equivalent Level of Safety
The requirements of this PAS are not intended to constrain innovation, The manufacturermay consider fuels, materials, designs or constructions not specifically dealt with in this PASThese alternatives should be evaluated as to their ability to yield levels of safety equivalent tothose prescribed by this PAS.
