| Title | Protection against lightning - Part 3: Physical damage to structures and life hazard |
| Project Number | 22662 |
| Abstract/Scope | 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). |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
