标准范围

IEC 62858:2019作为IEC 62858:2019 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 62858:2019介绍并讨论了所有必要的措施，以使从各国闪电定位系统（LLSs）获得的地闪密度、NG和地闪点密度、NSG值可靠且均匀。仅考虑与风险评估相关的参数。这第二版取消并取代了2015年出版的第一版。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:-引入了两个信息性附件，涉及确定用于风险计算的闪电密度（附件A）和地面撞击点计算方法（附件B）。

IEC 62858:2019 is available as IEC 62858:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62858:2019 introduces and discusses all necessary measures to make reliable and homogeneous the values of ground flash density, NG and ground strike point density, NSG, obtained from lightning location systems (LLSs) in various countries. Only parameters that are relevant to risk assessment are considered. This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- Two informative annexes are introduced dealing with the determination of lightning density for risk calculation (Annex A) and ground strike point calculation methods (Annex B).
