IEC 62282-3-100:2012

Fuel cell technologies - Part 3-100: Stationary fuel cell power systems - Safety

IEC 62282-3-100:2012 is applicable to stationary fuel cell power systems intended for indoor and outdoor commercial, industrial and residential use in non-hazardous (unclassified) areas. It contemplates all significant hazards, hazardous situations and events, with the exception of those associated with environmental compatibility (installation conditions), relevant to fuel cell power systems, when they are used as intended and under the conditions foreseen by the manufacturer.

Technologies des piles à combustible - Partie 3-100: Systèmes à piles à combustible stationnaires - Sécurité

L'IEC 62282-3-100:2012 s'applique aux systèmes à piles à combustibles stationnaires destinés à un usage à l'intérieur et à l'extérieur, commercial, industriel ou d'habitation, dans des zones non dangereuses (non classées). Elle traite de tous les dangers importants, situations et évènements dangereux, à l'exception de ceux associés à la compatibilité environnementale (conditions d'installation), relatifs aux systèmes à piles à combustible, lorsqu'ils sont utilisés comme prévu et selon les conditions prévues par le fabricant.
