and in addition
to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees;
any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International,
governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC
collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions
determined by agreement between the two organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all interested
National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form of
standards, technical specifications, technical reports or guides and they are accepted by the National Committees in
that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any divergence
between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.

1.1 System Boundary
1.1.1 This consumer safety standard covers fuel cell power systems and fuel cartridges that are
wearable or easily carried by hand, providing dc outputs that do not exceed 60 V d.c. and power
output of 240 VA. As such, the internal and external circuitry are considered circuits that are
SELV as defined in IEC 60950-1, and are considered to be limited power circuits if further
compliance with IEC 60950-1, Section 2.5 is demonstrated.
1.1.2 This consumer safety specification covers all fuel cell power system, units and cartridges.
This specification establishes requirements for all fuel cell power system, units and cartridges to
ensure a reasonabl
