Omfang

IEC 62561-8:2026 specifies the requirements and tests for components used for electrically insulated LPS. These components, which can reduce the separation distance, are as follows:- insulating stand-offs, used in conjunction with an air-termination system and down-conductors with the aim of maintaining the proper separation distance;- insulating down‑conductors, including their specific fasteners.Testing of insulating stand-offs and insulating down-conductor components for an explosive atmosphere is not covered by this document. This first edition cancels and replaces IEC TS 62561-8 published in 2018. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to IEC TC 62561-8:2018:a) title and scope of the standard has been adjusted;b) the document has been updated in line with IEC 60068-2-52:2017 on salt mist treatment;c) the document has been updated in line with ISO 22479:2019 on humid sulphureous atmosphere treatment;d) two different possible example configurations for pull out tests have been introduced;e) additional information on pollution has been included;f) an alternate test arrangement for high voltage impulse test has been included;g) a new normative Annex H for applicability of previous tests has been introduced;h) pass criteria for high voltage impulse testing updated;i) explanation on high voltage impulse testing with negative polarity has been added.
