Full Description

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 1000Vr.m.s. AC in the range 45Hz to 65Hz and 1500V DC. This second edition cancels and replaces the first edition published in 1991 and IECTS61813:2000. 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 IEC61318:2007;
c) distinguishes between tests for hollow booms and those for foam filled booms;
d) references ISO16368 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 IECTS61813 for care, maintenance and in-service testing of aerial devices with insulating booms.
