IEC 62561-8-ed.1.0-CMV

Annotation of standard text IEC 62561-8-ed.1.0-CMV :

This commented version (CMV) of the official IEC Standard allows the user to identify the changes made to the previous edition IEC TS 62561-8:2018. A vertical bar appears in the margin wherever a change has been made. Additions are in green text, deletions are in strikethrough red text. 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.
