This International Standard is applicable to insulating aerial devices for mounting on a chassis, to be used for live working on electrical installations at nominal voltages above 1 000V r.m.s. a.c. and 1 500V d.c. The primary purpose of an aerial device is for work positioning of personnel. Other devices such as jibs may be fitted in order to assist the operator in performing the work. This document also includes requirements and tests for the parts of the chassis influencing the performance of the insulating aerial devices to be used for live working. When mounted on a chassis, the insulating aerial device becomes a component of a mobile elevating work platform (MEWP). Complementary requirements for the resulting MEWP are included in ISO 16368. Unless otherwise stated, the use of the term aerial device in this document refers to insulating aerial device . The products designed and manufactured according to this standard contribute to the safety of the users provided they are used by skilled persons, in accordance with safe methods of work and the instructions for use. NOTE Any requirements that are in conflict with or are meant to be complementary to ISO 16368 are delineated herein.
