(Main)Flanges and their joints - Gasket parameters and test procedures relevant to the design rules for gasketed circular flange connections
Flanges and their joints - Gasket parameters and test procedures relevant to the design rules for gasketed circular flange connections
This European Standard specifies the gasket parameters required by EN 1591 1 and provides the test procedures for establishing the values of these parameters.
Gaskets which are wholly based upon elastomers, or based upon elastomers with only the inclusion of particulate fillers or particulate reinforcement, as opposed to gaskets combining elastomers, fillers and fibrous reinforcement, are beyond the scope of this document.
NOTE The testing procedures given might be applicable to gaskets of other shapes and dimensions.
Flansche und ihre Verbindungen - Dichtungskennwerte und Prüfverfahren für die Anwendung der Regeln für die Auslegung von Flanschverbindungen mit runden Flanschen und Dichtungen
Diese Europäische Norm legt die nach EN 1591-1 geforderten Dichtungskennwerte fest und enthält die Prüfverfahren zur Festlegung der Zahlenwerte dieser Kennwerte.
Dichtungen, die gänzlich auf Elastomeren basieren oder die auf Elastomeren mit lediglich dem Einschluss feinteiliger Füllstoffe oder feinteiliger Verstärkungen basieren, liegen im Gegensatz zu Dichtungen, in denen Elastomere, Füllstoffe und Faserverstärkungen miteinander kombiniert werden, nicht im Anwendungsbereich dieses Dokumentes.
ANMERKUNG Die enthaltenen Prüfverfahren können auch für andere Dichtungsformen und -maße angewendet werden.
Brides et leurs assemblages - Paramètres de joints et procédures d'essai relatives aux règles de calcul des assemblages à brides circulaires avec joint
Le présent document définit les paramètres de joints requis par l’EN 1591 1 et décrit les modes opératoires d’essai permettant de déterminer les valeurs de ces paramètres.
Les joints entièrement fabriqués en matériaux élastomères ou fabriqués à partir de matériaux élastomères additionnés uniquement de charges particulaires ou de renforts sous forme de particules, par opposition aux joints combinant des matériaux élastomères, des charges et des renforts fibreux, ne relèvent pas du domaine d’application du présent document.
NOTE Les modes opératoires d'essai indiqués peuvent s'appliquer à des joints ayant d'autres formes et dimensions.
Prirobnice in prirobnični spoji - Preskusni postopki za določanje parametrov tesnil, ki so potrebni za konstruiranje prirobičnih spojev, sestavljenih iz okroglih prirobnic in tesnil
EN 13555 določa parametre tesnil, kakor zahteva EN 1591-1, in zagotavlja preskusne postopke za določanje vrednosti teh parametrov. Tesnila, ki popolnoma temeljijo na elastomerih ali elastomerih s polnili z delci ali z ojačitvijo z delci, v nasprotju s tesnili, ki združujejo elastomere, polnila in polnila z delci, niso del tega dokumenta.

Introduction
This document provides the test procedures to allow the generation of the gasket parameters to enable the
design equations established in EN 1591-1 to be employed. The same test procedures may be used for “Type
Testing” of gaskets and gasket materials. These procedures are not for routine quality control purposes.
1 Scope
This European Standard specifies the gasket parameters required by EN 1591-1 and provides the test
procedures for establishing the values of these parameters.
Gaskets which are wholly based upon elastomers, or based upon elastomers with only the inclusion of
particulate fillers or particulate reinforcement, as opposed to gaskets combining elastomers, fillers and fibrous
reinforcement, are beyond the scope of this document.
NOTE The testing procedures given might be applicable to gaskets of other shapes and dimensions.
