Annotation of standard text ČSN EN 1487 (135800):

Tato norma stanovuje rozměry, materiály a funkční požadavky (včetně zkušebních postupů) na hydraulické pojistné skupiny o jmenovitých světlostech (jmenovitých průměrech) DN 15 až DN 25 s pracovními tlaky 0,1 MPa až 0,7 MPa. Hydraulické pojistné skupiny jsou určeny pro osazení na přívod pitné vody do zásobníkových ohřívačů vody s teplotou v zásobníku nejvíce 95 °C. Hydraulické pojistné skupiny omezují tlak v ohřívači vody a zabraňují jak zpětnému průtoku vody do vodovodu, tak styku odtečené vody s vodou v ohřívači
