Annotation of standard text IEC 61821-ed.2.0 :
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. La CEI 61821:2011 sapplique a la maintenance des circuits serie a courant constant pour le balisage aeronautique au sol (AGL). Cette norme internationale: - couvre les circuits serie a courant constant pour le balisage aeronautique au sol installe dans les aerodromes et les heliports; - se concentre sur la fourniture dexigences en matiere de securite pour la maintenance des circuits serie a courant constant pour le balisage aeronautique au sol. Lexistence dune diversite de circuits serie a courant constant pour balisage aeronautique au sol, possedant des caracteristiques et des parametres differents dun circuit a lautre, est admise; - sinteresse principalement a la securite des personnes et specifie les regles et les principes fondamentaux lies a la maintenance des circuits serie a courant constant pour le balisage aeronautique au sol; - ne sapplique pas aux circuits serie primaires pour le balisage aeronautique au sol alimentes directement a partir dune source a tension constante provenant du secteur; - ne sapplique pas a leclairage public des rues ou des routes, ou a toute autre installation requerant lutilisation de circuits serie a courant constant. Cette deuxieme edition annule et remplace la premiere edition parue en 2002. Elle constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) ajout de references dans les references normatives; b) ajout de notes dans les Articles 5, 6 et 7; c) modification des procedures de pre-travail dans le point e) du 7.2.2.
