This part of IEC 62561 specifies the requirements and tests for devices intended to count the number of lightning strikes based on the current flowing in a conductor. This conductor may be part of a lightning protection system (LPS) or connected to an SPD installation or other conductors, which are not intended to conduct a significant portion of lightning currents.
LSCs for use in hazardous atmospheres, extra requirements for the components may be necessary to be taken.
NOTE In CENELEC countries, testing requirements of components for explosive atmosphere are specified in CLC/TS 50703-2.

This part of IEC 62561 specifies the requirements and tests for metallic connection
components that form part of a lightning protection system (LPS). Typically, these can be
connectors, clamps, bonding and bridging components, expansion pieces and test joints.
For the purposes of this document the following connection types are considered as
connection components: exothermic, brazing, welding, clamping, crimping, seaming, screwing
or bolting.
Testing of components for an explosive atmosphere is not covered by this document.

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.

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.

EN-IEC 62858 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 International Standard describes the characteristics of thunderstorm warning systems and evaluation of the usefulness of lightning real time data and/or storm electrification data in order to implement lightning hazard preventive measures.
This standard provides the basic requirements for sensors and networks collecting accurate data of the relevant parameters, giving real-time information of lightning tracks and range. It describes the application of the data collected by these sensors and networks in the form of warnings and historical data.
This standard applies to the use of information from thunderstorm warning systems (systems or equipment providing real-time information) on atmospheric electric activity in order to monitor preventive measures.
This standard includes:
• a general description of available lightning and storm electrification hazard warning systems;
• a classification of thunderstorm detection devices and properties;
• guidelines for alarming methods;
• a procedure to determine the usefulness of thunderstorm information;
• some informative examples of possible preventive actions.
The following aspects are outside the scope of this standard:
a) lightning protection systems; such systems are covered by the IEC 62305 series;
b) other thunderstorm related phenomena such as rain, hail, wind;
c) satellite and radar thunderstorm detection techniques.
A non-exhaustive list of situations to which this standard could be applicable is given below:
• people in open areas involved in activities such as maintenance, labour, sports, competitions, agriculture and fisheries or situations where large crowds gather;
• wind farms, large solar power systems, power lines;
• occupational health and safety prevention;
• sensitive equipment such as computer systems, emergency systems, alarms and safety equipment;
• operational and industrial processes;
• storage, processing and transportation of hazardous substances (e.g. flammable, radioactive, toxic and explosive substances);
• determined environments or activities with special danger of electrostatic discharges (e.g. space and flight vehicle operations);
• operations in which the continuity of the basic services is very important (e.g. telecommunications, the generation, transport and distribution of energy, sanitary services and emergency services);
• infrastructures: ports, airports, railroads, motorways and cableways;
