A mathematical angle calculation used primarily for simple buildings or vertical rods. The angle varies dynamically depending on the height of the air terminal and the assigned LPL class. Down-Conductor System

: Clarified calculation methods (general and simplified) to prevent "side-flashing" between conductors and internal metal parts. Modern Structures : Updated guidance for protecting complex designs, such as green roofs and tall building facades. Component Compliance : Mandates that all components meet the IEC 62561 series standards for reliability. How to Access the Official PDF

The standard outlines three main systems that form the backbone of structural lightning protection: Skytree Scientific Air-termination systems

The primary objective of Part 3 is to automate safety procedures that prevent mechanical destruction and fire caused by direct lightning flashes. The standard achieves this by specifying requirements for:

When a down-conductor carries lightning current, a huge voltage drop occurs across its length. If metallic objects or electrical cables inside the building are located too close to the down-conductor, the electricity can "flashover" through the wall. Engineers must calculate the using the standard formula:
