Title Electrical installations for lighting and beaconing of aerodromes - Maintenance of aeronautical ground lighting constant current series circuits
Project Number 23005
Abstract/Scope IEC 61821:2011 applies to the maintenance of AGL constant current series circuits. This International Standard: - covers constant current series circuits for AGL installed at aerodromes and heliports; - concentrates on providing the safety requirements for the maintenance of an AGL constant current series circuit. It is recognized that AGL constant current series circuits of different design characteristics and parameters are in existence; - is mainly concerned with safety to persons by specifying the rules and fundamental principles for the maintenance of AGL constant current series circuits; - is not intended to apply to AGL primary series circuits supplied directly from a mains constant voltage source; - is not intended to be used for public street lighting, roadway lighting or any other installation requiring the use of constant current series circuits. This second edition cancels and replaces the first edition published in 2002. It is a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of references to normative references; b) addition of notes in Clauses 5, 6 and 7; c) modification of pre-work procedures in item e) of 7.2.2.

(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Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn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.
