Introduction
This European Standard specifies health and safety requirements, as well as some functional and
performance requirements, for conveyor belt vehicles intended for loading/unloading of individual
items of baggage or cargo on/off 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 conveyor belt vehicles. Deviations should occur only after careful
consideration, extensive testing, risk assessment and thorough service evaluation have shown
alternative methods or conditions to be satisfactory. Such deviations are outside the scope of this
standard and a manufacturer should be able to demonstrate an equivalent level of protection.
This European Standard is a Type C standard as stated in EN ISO 12100.
When provisions of this Type C standard are different from those that 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. Deviations from requirements do not fall within the presumption of conformity given by the
standard.
1 Scope
This European Standard specifies the technical requirements to minimize the hazards listed in Clause 4
that can arise during the commissioning, operation and maintenance of conveyor belt vehicles when
used as intended, including misuse reasonably foreseeable by the manufacturer, when carried out in
accordance with the specifications given by the manufacturer or his autho
