La présente Norme européenne spécifie les dimensions, aux types de connexions, aux matériaux utilisés, au marquage et exigences relatives aux essais des raccords pour flexibles équipés de demi raccords symétriques (système Guillemin) à verrou mobile pour des assemblages flexibles destinés à être utilisés à une pression de service maximale de 10 bar ) munis de douilles conformes à l’EN 14420 2 et de demi-coquilles conformes à l’EN 14420 3. Les raccords conformes au présent document sont utilisés pour relier les tuyaux et les connexions destinés au transport de liquides, de matières solides (par exemple des matières pulvérulentes ou granulaires) à l'exception des gaz liquéfiés et de la vapeur. La plage de température de service est de 20 °C à + 65 °C.

Cevni fitingi z objemkami - 8. del: Simetrična spojka (sistem Guillemin)

Ta evropski standard določa dimenzije, vrste priključkov, kakovost materialov, zahteve za označevanje in zahteve za preskušanje za cevne fitinge s simetrično spojko (sistem Guillemin) in premičnim zaklepnim obročem, za cevne priključke z največjim delovnim tlakom do 10 barov1), s cevnimi nastavki v skladu z EN 14420-2 in z objemkami v skladu z EN 14420-3. Spojke v skladu s tem dokumentom se uporabljajo za povezovanje cevi in priključkov za prevoz tekočin, trdnih snovi (npr. praški, granule), razen tekočega plina in pare. Delovna temperatura je med -20 °C in +65 °C.
