This European Standard for a single series of flanges specifies requirements for circular steel flanges in PN designations PN 2,5 to PN 100 and nominal sizes from DN 10 to DN 4000.
This standard specifies the flange types and their facings, dimensions, tolerances, threading, bolt sizes, flange jointing face surface finish, marking, materials, pressure/ temperature ratings and approximate flange masses.
This standard does not apply to flanges made from bar stock by turning, or to flanges of types 11, 12 and 13 made from plate material.

Flansche und ihre Verbindungen - Runde Flansche für Rohre, Armaturen, Formstücke und Zubehörteile, nach PN bezeichnet - Teil 1: Stahlflansche

Diese Europäische Norm über eine einzelne Flanschenreihe legt Anforderungen fest für runde Stahlflansche mit den
PN-Stufen PN 2,5 bis PN 100 und den Nennweiten DN 10 bis DN 4 000.
Diese Norm legt die Flanschtypen und ihre Dichtflächenformen, Maße, Toleranzen, Gewinde, Schraubengrößen,
Oberflächenbeschaffenheit der Dichtflächen der Flanschverbindung, Kennzeichnung, Werkstoffe, Druck/Temperatur-
Zuordnungen und ungefähre Flanschgewichte fest.
Diese Norm gilt nicht für Flansche, die aus Stangenmaterial gedreht werden und nicht für Flansche der Typen 11,
12 und 13 aus Blech.

Brides et leurs assemblages - Brides circulaires pour tubes, appareils de robinetterie, raccords et accessoires désignées PN - Partie 1: Brides en acier

La présente norme européenne pour un seul système de brides spécifie les prescriptions pour les brides circulaires en acier avec les désignations PN 2,5 à PN 100 et les diamètres nominaux DN 10 à DN 4000.
La présente norme définit les types de brides et leurs portées de joint, les dimensions, les tolérances, les filetages, les dimensions des boulons, les états de surface des faces de joints des brides, le marquage, les matériaux, les relations pression/température et les masses approximatives des brides.
La présente norme ne s'applique pas aux brides fabriquées par tournage à partir de barres, ni aux brides de types 11, 12 et 13 fabriquées à partir de tôles.
