  • SCOPE

    1 Scope

    1.1 These requirements cover hand-held or hand-transportable direct borohydride alkaline fuel cell power units fueled with single use borohydride compound fuel cartridges or hand-held or hand-transportable single use direct borohydride alkaline fuel cell power units with an integral borohydride compound fuel cartridge. The fuel utilized to fuel the systems consists of either sodium or potassium borohydride compound or a mixture of these compounds, which is considered a Class 8 (corrosive) material.

    1.2 These requirements apply to power units that provide dc outputs rated 60 Vdc or less and 240 VA or less. As such, the internal and external circuitry is considered safety extra low voltage, "SELV."

    1.3 The fuel cell power units covered by these requirements are for use in unclassified (ordinary) locations in ambient temperatures that do not exceed 50°C (121°F).

    1.4 Federal regulatory requirements pertaining to the shipment of fuel cartridges is outside the scope of this Outline of Investigation.
