Live working - Insulating aerial devices for mounting on a chassis

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.
