SIST EN 62282-3-100:2012

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

IEC 62282-3-100:2012(E) 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.

Tehnologije gorivnih celic - 3-100. del: Nepremični elektroenergetski sistemi z gorivnimi celicami - Varnost

Ta del standarda IEC 62282 se uporablja za nepremične, samostojne elektroenergetske sisteme z gorivnimi celicami ali elektroenergetske sisteme z gorivnimi celicami, ki so izdelani iz tovarniško sestavljenih paketov integriranih sistemov, ki proizvajajo električno energijo z elektrokemičnimi reakcijami. Ta standard se uporablja za sisteme – ki so namenjeni za električno povezavo z glavnim električnim omrežjem, neposredno ali prek prenosnega stikala, ali s samostojnim sistemom za distribucijo električne energije; – ki so namenjeni za dobavo enosmernega ali izmeničnega toka; – s sposobnostjo pridobivanja koristne toplote ali brez nje; – ki so namenjeni za delovanje na naslednje vrste vhodnega goriva: a) zemeljski plin in drugi plini, bogati z metanom, ki izhajajo iz obnovljivih virov (biomase) ali virov fosilnega goriva, na primer deponijski plin, plin gnilišča, premogovniški plin; b) goriva, ki izhajajo iz rafiniranja nafte, na primer dizel, bencin, kerozin, utekočinjeni naftni plini, kot sta propan in butan; c) alkoholi, estri, etri, aldehidi, ketoni, tekočine na podlagi postopka Fischer-Tropsch in druge primerne organske spojine, bogate z vodikom, ki izhajajo iz obnovljivih virov (biomase) ali virov fosilnega goriva, na primer metanol, etanol, dimetil eter, biodizel; d) vodik, plinaste mešanice, ki vsebujejo vodikov plin, na primer sintetični plin, mestni plin. Ta standard ne zajema: – elektroenergetskih sistemov z mikro gorivnimi celicami; – premičnih elektroenergetskih sistemov z gorivnimi celicami; – elektroenergetskih pogonskih sistemov z gorivnimi celicami. Ta standard se uporablja za nepremične elektroenergetske sisteme z gorivnimi celicami, ki so namenjeni za notranjo in zunanjo komercialno, industrijsko in zasebno uporabo na nenevarnih (nerazvrščenih) območjih. Ta standard obravnava vsa večja tveganja, nevarne razmere in dogodke, razen tistih, ki so povezani z okoljsko združljivostjo (pogoji namestitve), v zvezi z elektroenergetskimi sistemi z gorivnimi celicami, ki se uporabljajo v skladu z namenom in pod pogoji, ki jih je predvidel proizvajalec. Ta standard obravnava pogoje, ki lahko na eni strani povzročijo nevarnost za ljudi, na drugi strani pa lahko pomenijo nevarnost poškodb zunaj sistema z gorivnimi celicami. Ta standard ne vključuje zaščite pred poškodbami notranjosti sistema z gorivnimi celicami, če te ne pomenijo nevarnosti zunaj tega sistema. Zahteve iz tega standarda niso namenjene omejevanju inovacij. Goriva, materiale, načrtovanja ali zgradbe, ki niso posebej obravnavani v tem standardu, je treba ovrednotiti glede na njihovo sposobnost zagotavljanja ravni varnosti in delovanja, enakovredne ravnem iz tega standarda.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees;
