Le présent document spécifie les exigences en matière d'installation électrique spécifiques aux systèmes d'éclairage de sécurité, ainsi que les exigences d'essai et de documentation relatives à la vérification, à l'exploitation et à la maintenance de tels systèmes. NOTE 1 L'éclairage de sécurité englobe l'éclairage des chemins d'évacuation, l'éclairage d'ambiance (anti-panique), l'éclairage d'une zone spécifique et l'éclairage des emplacements de travaux dangereux. Les signaux de sécurité des chemins d'évacuation font partie de l'éclairage de sécurité. NOTE 2 Les systèmes d'éclairage de sécurité incluent les systèmes adaptatifs et non adaptatifs, ainsi que les systèmes installés en position haute et en position basse. Le présent document ne couvre pas les exigences relatives à l'éclairage de remplacement. NOTE 3 Les systèmes utilisés pour l'éclairage de remplacement peuvent également être utilisés pour l'éclairage de sécurité, sous réserve que les exigences correspondantes soient respectées (voir l'EN 1838).
