IEC 61057:2017 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. AC in the range 45 Hz to 65 Hz and 1 500V DC. This second edition cancels and replaces the first edition published in 1991 and IEC TS 61813:2000. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a)   general review of the requirements and test provisions;
b)   preparation of the elements of evaluation of defects, and general application of IEC 61318:2007;
c)   distinguishes between tests for hollow booms and those for foam filled booms;
d)   references ISO 16368 for particular mechanical tests;
e)   further information on vacuum protection and leakage current monitoring and a mandatory requirement that aerial devices for bare hand work be fitted with a permanently installed lower test electrode system;
f)    controls of high electrical resistance;
g)   reference to SAE for insulating hydraulic hoses;
h)   inclusion of IEC TS 61813 for care, maintenance and in-service testing of aerial devices with insulating booms.
