This supplementary standard defines the Environment and Performance tests for a Self Contained Man Worn Man Portable Methanol Fuel Cell System (MWMPMFC) here after referenced as the fuel cell.

This system will operate without the need for an external hybridised battery or other energy source and will be limited to providing dc outputs that do not exceed 60V d.c. and power output that does not exceed 240 watts. As such, the externally accessible circuitry is considered as circuits that are "SELV" as defined in IEC 60950-1.
