This document describes the characteristics of thunderstorm warning systems (TWSs) in order
to implement lightning hazard preventive measures.
Single sensors and/or a network of sensors (e.g. lightning location system) can be used as a
TWS.
This document provides requirements for sensors and networks collecting accurate data of the
relevant parameters, giving real-time information on lightning and atmospheric electric activity.
It describes the application of the data collected by these sensors and networks in the form of
warnings and historical data.
This document includes:
• a general description of available techniques for TWSs;
• guidelines for alarming methods;
• informative examples of possible preventive actions.
The following aspects are outside the scope of this document:
a) lightning protection systems: such systems are covered by IEC 62305 (all parts) [1]1;
b) other thunderstorm related phenomena such as rain, hail, wind;
c) satellite and radar based thunderstorm detection techniques;
d) portable devices (a device where the sensor is not fixed).
NOTE It is possible that calibration and testing of portable devices will not be sufficient to provide efficient warning.

This document defines the requirements and testing for joints of metal sheets, with or without insulating coatings, used as natural components in roofs, facades or walls of buildings, suitable to conduct lightning current in LPS where the interconnection of these metal sheets does not ensure durable electrical connection.
NOTE   This document does not deal with the lightning interception capabilities of these components. The connection clamps for connecting the metallic sheet with the down conductor to the earth termination system are LPSC, tested according to EN 62561 1.

• earth-termination systems of telecommunication systems,
• auxiliary earth electrodes of voltage-operated, earth fault circuit breakers,
• rail earth electrode of power and DC railways,
• measuring earth electrodes for laboratories,
• installations with cathodic protection and stray current systems,
• service entry masts for low-voltage overhead cables,
• bypassing insulated flanges and insulated couplings of pipelines.
This does not cover applications where follow currents occur.

IEC 62305-2:2010(E) is applicable to risk assessment for 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 allows the selection of appropriate protection measures to be adopted to reduce the risk to or below the tolerable limit. This second edition cancels and replaces the first edition, published in 2006, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: 1) Risk assessment for services connected to structures is excluded from the scope. 2) Injuries of living beings caused by electric shock inside the structure are considered. 3) Tolerable risk of loss of cultural heritage is lowered from 10-3 to 10-4. The value of tolerable risk of loss of economic value (RT = 10-3) is introduced, to be used when data for cost/benefit analysis are not available. 4) Extended damage to surroundings structures or to the environment is considered. 5) Improved equations are provided for evaluation of: - collection areas relevant to flashes nearby a structure, - collection areas relevant to flashes to and nearby a line, - probabilities that a flash can cause damage, - loss factors even in structures with risk of explosion, - risk relevant to a zone of a structure, - cost of loss. 6) Tables are provided to select the relative amount of loss in all cases. 7) Impulse withstand voltage level of equipments was extended down to 1 kV.

IEC 62305-3 provides the requirements for protection of a structure against physical damage by means of a lightning protection system (LPS), and for protection against injury to living beings due to touch and step voltages in the vicinity of an LPS (see IEC 62305-1). This standard is applicable to design, installation, inspection and maintenance of an LPS for structures without limitation of their height and to establishment of measures for protection against injury to living beings due to touch and step voltages.

This part of IEC 62305 provides the general principles to be followed in the protection against lightning of structures including their installations and contents as well as persons. The following cases are outside the scope of this standard: railway systems; vehicles, ships, aircraft, offshore installations; underground high pressure pipelines; pipe, power and telecommunication lines not connected to a structure.

This international standard provides information for the design, installation, inspection, maintenance and testing of electrical and electronic system protection (ESP), and measures to reduce the risk of permanent failures due to lightning electromagnetic impulse (LEMP) within a structure. He does not cover protection against electromagnetic interference due to lightning, which may cause malfunctioning of electronic systems. However, the information reported in Annex A can also be used to evaluate such disturbances. This draft international standard does not deal with detailed design of the electrical and electronic systems themselves.

IEC 62305-3:2010(E) provides the requirements for protection of a structure against physical damage by means of a lightning protection system (LPS), and for protection against injury to living beings due to touch and step voltages in the vicinity of an LPS (see IEC 62305-1). This second edition cancels and replaces the first edition, published in 2006, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: 1) Minimum thicknesses of metal sheets or metal pipes given in Table 3 for air-termination systems are assumed as not able to prevent hot-spot problems. 2) Steel with electro-deposited copper is introduced as material suitable for LPS. 3) Some cross-sectional areas of LPS conductors were slightly modified. 4) For bonding purposes, isolating spark gaps are used for metal installations and SPD for internal systems. 5) Two methods - simplified and detailed - are provided for evaluation of separation distance. 6) Protection measures against injuries of living beings due to electric shock are considered also inside the structure. 7) Improved information for LPS in the case of structures with a risk of explosion are given in Annex D (normative).
