IEC 62305-1:20 24提供了结构（包括其装置和内容物以及人员）防雷的一般原则。 以下情况超出了本文档的范围: -铁路系统； -车辆、船舶、飞机、海上设施； -地下高压管道； -与结构分离的管道、电力和电信线路； -核电站。 这第三版取消并取代了2010年出版的第二版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: a)附录D中引用了IEC 62561系列，以提供与根据IEC 62561系列的相关防雷系统组件的链接；b)风险管理引入了与公众相关的损失类型的概念； c)引入了可能损害结构内内部系统可用性的损伤频率的概念； d)对于低压电力系统和电信系统中的SPD尺寸，已经更准确地指定了由闪电引起的浪涌电流。

IEC 62305-1:2024 provides general principles for the protection of structures against lightning, including their installations and contents, as well as persons.
The following cases are outside the scope of this document:
- railway systems;
- vehicles, ships, aircraft, offshore installations;
- underground high-pressure pipelines;
- pipe, power and telecommunication lines separated from the structure;
- nuclear power plants.
This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) reference to the IEC 62561 series is made in Annex D to provide a link to relevant lightning protection system components according to the IEC 62561 series;
b) risk management introduces the concept of types of loss with public relevance;
c) the concept of frequency of damage that can impair the availability of the internal systems within the structure has been introduced;
d) surge currents due to lightning flashes have been more accurately specified for SPD dimensioning in low-voltage power systems and in telecommunication systems.
