Cevne armature z objemkami za pretočne cevi za utekočinjeni naftni plin (LPG)

Ta evropski standard določa zahteve za dimenzije, opisovanje, materiale, označevanje in preskušanje za vrsto cevnih fitingov, ki se lahko uporabljajo z gumenimi/polimernimi cevmi za prevoz utekočinjenega naftnega plina, LPG, v tekočem ali plinastem stanju in zemeljskega plina. Največji delovni tlak je 25 barov1). Pri običajnem delovanju je temperatura od -30 °C do 70 °C, pri delovanju pri nizkih temperaturah pa od -50 °C do 70 °C. Nominalna velikost cevnih fitingov z notranjimi in zunanjimi navoji je od DN 15 do DN 75, za cevne fitinge s prirobnicami pa od DN 15 do DN 200. Poleg fitingov iz tega evropskega standarda se lahko za LPG uporabljajo tudi navojni priključki v skladu z EN 14420-5 in cevni fitingi z vijačnimi pušami v skladu z EN 14424 do velikosti DN 25.
