Annotation of standard text IEC 62554-ed.1.0 :
IEC 62554:2011 specifies sample preparation methods for determining mercury levels in new tubular fluorescent lamps (including single capped, double capped, self-ballasted and CCFL for backlighting) containing 0,1 mg mercury or more. The intended resolution of the methods described in this standard is of the order of 5 %. Mercury level measurement of spent lamps is excluded, as during lamp operation, mercury gradually diffuses into the glass wall and reacts with the glass materials. The test method of this standard does not recover mercury that is diffused into or reacted with or otherwise incorporated irreversibly with the glass wall of discharge tubes. This standard does not contain information on measurement. Measurement is specified in IEC 62321. La CEI 62554:2011 specifie les methodes de preparation des echantillons en vue de la determination des niveaux de mercure dans des lampes tubulaires a fluorescence (y compris celles a un culot, a deux culots, a ballast incorpore et les CCFL pour le retro-eclairage) dont la teneur en mercure est de 0,1 mg ou superieure. La resolution prevue des methodes decrites dans la presente norme est de lordre de 5 %. La mesure du niveau de mercure des lampes usagees est exclue car au cours du fonctionnement de la lampe, le mercure se diffuse progressivement dans la paroi de verre et reagit aux materiaux de verre. La methode dessai de la presente norme ne recupere pas le mercure qui sest diffuse dans la paroi de verre des tubes a decharge ou ayant reagi avec cette paroi de verre ou encore qui sest incorpore dans celle-ci de maniere irreversible. La presente norme ne contient aucune information relative aux mesures. Les mesures sont specifiees dans la CEI 62321.
