Annotation of standard text IEC 62305-1-ed.3.0 :
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. LIEC 62305-1:2024 fournit des principes generaux de protection des structures contre la foudre, y compris leurs installations, leur contenu et les personnes qui sy trouvent. Les cas suivants ne relevent pas du domaine dapplication du present document: - chemins de fer; - vehicules, navires, avions, installations en mer; - canalisations enterrees a haute pression; - canalisations, lignes de puissance et de communication separees de la structure; - centrales nucleaires de puissance. Cette troisieme edition annule et remplace la deuxieme edition parue en 2010. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) a lAnnexe D, il est fait reference a la serie IEC 62561 pour faire le lien avec les composants des systemes de protection contre la foudre correspondants selon la serie IEC 62561; b) la gestion des risques introduit le concept des types de pertes qui revetent une importance publique; c) introduction du concept de frequence des dommages qui peuvent influencer la disponibilite des reseaux internes a la structure; d) les courants de surcharge dus aux coups de foudre ont ete specifies avec davantage de precision pour le dimensionnement des SPD dans des systemes dalimentation basse tension et dans les reseaux de communication.
