Varnostne in nadzorne naprave za gorilnike in aparate na plin ali tekoča goriva - Regulacijske in nadzorne funkcije v elektronskih sistemih - 2. del: Regulacija in nadzor razmerja goriva in zraka za elektronski tip

Ta evropski standard določa varnostne in konstrukcijske zahteve ter zahteve glede zmogljivosti za elektronski sistem z regulacijo razmerja goriva in zraka (ERC), elektronski sistem z nadzorom razmerja goriva in zraka (ERS) ter elektronski sistem z uravnoteženjem razmerja goriva in zraka (ERT), ki so namenjeni uporabi z gorilniki in aparati na plin ali tekoča goriva. Prav tako opisuje preskusne postopke za vrednotenje teh zahtev ter vsebuje potrebne informacije za namestitev in uporabo.
Ta evropski standard se uporablja za:
– zaprtozančne sisteme z regulacijo razmerja goriva in zraka (glej točko 3.101);
– sisteme z nadzorom razmerja goriva in zraka (glej točko 3.102);
– zaprtozančne sisteme z uravnoteženjem razmerja goriva in zraka (glej točko 3.103);
ter ne razlikuje med razvrstitvami glede na vhodno toplotno moč.
OPOMBA 1: Evropski standardi za gorilnike, aparate ali procese, ki uporabljajo elektronski sistem z regulacijo razmerja goriva in zraka, elektronski sistem z nadzorom razmerja goriva in zraka ter elektronski sistem z uravnoteženjem razmerja goriva in zraka lahko preglasijo zahteve tega standarda.
OPOMBA 2: Določbe v zvezi z nadzorom proizvodnje niso del tega evropskega standarda.
