Introduction
This European Standard specifies health and safety requirements, as well as some functional and performance
requirements for ground power equipment intended for the electrical supply for aircraft to be used on all aircraft
types commonly in service in civil air transport.
The minimum essential criteria are considered to be of primary importance in providing safe, serviceable, economical,
and practical ground power equipment. Deviations from the recommended criteria should occur only after careful
consideration, extensive testing, risk assessment and thorough service evaluation have shown alternative methods or
conditions to be satisfactory.
This European Standard is a Type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this European Standard.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of the other standards, for machines that
have been designed and built according to the provisions of this type C standard.
