EN 62305-3:2011

Protection against lightning - Part 3: Physical damage to structures and life hazard

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).

Blitzschutz - Teil 3: Schutz von baulichen Anlagen und Personen

Protection contre la foudre - Partie 3: Dommages physiques sur les structures et risques humains

La CEI 62305-3:2010 spécifie les exigences pour la protection d'une structure contre les dommages physiques par un système de protection contre la foudre (SPF) et pour la protection contre les blessures d'êtres vivants dues aux tensions de contact et de pas à proximité d'un SPF (voir la CEI 62305-1). Cette deuxième édition annule et remplace la première édition, parue en 2006, dont elle constitue une révision technique. La présente édition comprend les modifications techniques importantes suivantes par rapport à la précédente édition: 1) Les épaisseurs minimales des tôles ou canalisations métalliques indiquées dans le Tableau 3 pour les dispositifs de capture sont supposées comme non capables d'éviter les problèmes de points chauds. 2) L'acier comportant un dépôt électrolytique de cuivre est introduit comme matériau adapté aux SPF. 3) Certaines surfaces de section des conducteurs du système de protection ont été légèrement modifiées. 4) A des fins de liaison, des éclateurs sont utilisés pour les installations métalliques, tandis que le parafoudre est utilisé pour les réseaux internes. 5) Deux méthodes simplifiée et détaillée sont fournies pour l'évaluation de la distance de séparation. 6) Les mesures de protection contre les blessures d'êtres vivants dues à un choc électrique sont également prises en compte à l'intérieur de la structure. 7) Une information plus complète concernant le système de protection contre la foudre (SPF) dans le cas de structures présentant un risque d'explosion est fournie à l'Annexe D (normative). La présente version bilingue (2012-06) correspond à la version anglaise monolingue publiée en 2010-12.

Zaščita pred delovanjem strele - 3. del: Fizična škoda na zgradbah in nevarnost za živa bitja (IEC 62305-3:2010, spremenjen)

IEC 62305-3 podaja zahteve za zaščito zgradb pred fizično škodo s sistemom za zaščito pred delovanjem strele (LPS) in za zaščito pred poškodbami živih bitij zaradi napetosti dotika in napetosti koraka v bližini LPS (glej IEC 62305-1). Ta standard velja za projektiranje, namestitev, nadzor in vzdrževanje sistema LPS za zgradbe brez omejitve glede višine in za vzpostavitev ukrepov za zaščito pred poškodbami živih bitij zaradi napetosti dotika in koraka.

NACIONALNI UVOD

Standard SIST EN 62305-3 (sl), Zaščita pred delovanjem strele – 3. del: Fizična škoda na zgradbah in
nevarnost za živa bitja (IEC 62305-3:2010, spremenjen), 2011, ima status slovenskega standarda in je
