scope:

IEC 62561-4:2017 deals with the requirements and tests for metallic and non-metallic conductor fasteners that are used to retain and support the air-termination, down-conductor and earth-termination systems. This document does not cover the fixing of conductor fasteners to the fabric of structures due to the vast number and types used in modern day construction. LPSC can also be suitable for use in hazardous atmospheres. There are therefore additional requirements when installing the components in such conditions. This second edition cancels and replaces the first edition, published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - new detailed flow chart of the tests; - in Annexes A and B, composite fasteners have been added.
