Ta evropski standard se uporablja za:
– tlačne regulatorje z označenim najvišjim vhodnim tlakom do vključno 50 kPa (500 mbar) nazivnih velikosti priključkov do vključno DN 250 za uporabo z enim ali več gorivnih plinov v skladu s standardom EN 437;
– tlačne regulatorje, ki uporabljajo pomožno energijo;
– tlačne regulatorje z nadzorom razmerja med pnevmatskim plinom/zrakom, ki delujejo na podlagi nadzora izstopnega tlaka plina kot odziv na signal zračnega tlaka, signal diferenčnega zračnega tlaka in/ali signal tlaka peči (regulatorji z ničelnim tlakom so vključeni kot posebna vrsta tlačnega regulatorja z nadzorom razmerja med pnevmatskim plinom/zrakom);
– tlačne regulatorje z nadzorom razmerja med plinom/zrakom, ki spremenijo izstopni zračni tlak kot odziv na signal plinskega tlaka ali signal diferenčnega plinskega tlaka.
Ta evropski standard ne zajema:
– tlačnih regulatorjev, priključenih neposredno na omrežje za distribucijo plina, ali vsebnik, ki ohranja tlak pri običajni distribuciji;
– tlačnih regulatorjev, namenjenih za plinske naprave, ki jih je treba montirati na odprtem in so izpostavljene okolju;
