Protection against lightning - Part 2: Risk management
| 분야 | TC 81 : Lightning protection |
|---|---|
| 적용범위 | IEC 62305-2:2024 is applicable to the risk management of a structure due to lightning flashes to earth. Its purpose is to provide a procedure for the evaluation of such a risk. Once an upper tolerable limit for the risk has been selected, this procedure provides a means for the selection of appropriate protection measures to be adopted to reduce the risk to or below the tolerable limit. 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) The concept of a single risk, to combine loss of human life and loss due to fire, has been introduced. b) The concept of frequency of damage that can impair the availability of the internal systems within the structure has been introduced. c) The lightning ground strike-point density NSG has been introduced replacing the lightning flash density NG in the evaluation of expected average annual number of dangerous events. d) Reduction of a few risk components can be achieved by the use of preventive temporary measures activated by means of a thunderstorm warning system (TWS) compliant with IEC 62793. The risk of direct strike to people in open areas has been introduced, considering the reduction of that risk using a TWS. The content of the corrigendum 1 (2024-10) has been included in this copy. |
