IEC 60900:2018 is available as /2 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60900:2018 is applicable to insulated, insulating and hybrid hand tools used for working live or close to live parts at nominal voltages up to 1 000 V AC and 1 500 V DC. The products designed and manufactured according to this document 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 (where appropriate). This document has been prepared in accordance with the requirements of IEC 61477 where applicable. The products covered by this document may have an impact on the environment during some or all stages of its life cycle. These impacts can range from slight to significant, be of short term or long-term duration, and occur at the global, regional or local level. This document does not include requirements and test provisions for the manufacturers of the products, or recommendations to the users of the products for environmental improvement. This fourth edition cancels and replaces the third edition, published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of a third category of tools has been added, namely hybrid hand tools; b) introduction of a new informative Annex A on examples of insulated, insulating and hybrid hand tools. Key words: Live Working, Insulated, Insulating, Hand Tools The contents of the corrigendum of January 2019 have been included in this copy.
