(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 document specifies the design parameters of gaskets and gasket materials required by EN 1591 1 and pro-vides the test procedures for establishing the values of these parameters for inclusion in ENV 1591 2.
The testing procedures given might be applicable to gaskets of other shapes and dimensions but this shall be indi-cated in the report.
Gaskets which are wholly based upon elastomers, or based upon elastomer with the inclusion of particulate fillers or particulate reinforcement, are beyond the scope of this document.
Flansche und ihre Verbindungen - Dichtungskennwerte und Prüfverfahren für die Anwendung der Regeln für die Auslegung von Flanschverbindungen mit runden Flanschen und Dichtungen
Dieses Dokument legt die Kennwerte für die Auslegung von Dichtungen und Dichtungswerkstoffen nach den Anforde-
rungen in EN 1591-1 fest und enthält Prüfverfahren zur Festlegung der entsprechenden Zahlenwerte für die Aufnah-
me in ENV 1591-2.
Diese Prüfverfahren können auch für andere Dichtungsformen und Maße angewendet werden, jedoch muss dies im
Prüfbericht angegeben werden.
Dichtungen auf Elastomer-Basis ohne oder auch mit speziellen Füllstoffen oder Verstärkungen liegen nicht im An-
wendungsbereich dieser Norm.
Brides et leurs assemblages - Paramètres de joints et modes opératoires d'essai relatifs aux règles de calcul des assemblages à brides circulaires avec joint
Le présent document définit les paramètres de conception des joints et des matériaux d'étanchéité requis par
l�EN 1591-1 et décrit les modes opératoires d�essai permettant de déterminer les valeurs de ces paramètres
en vue de les inclure dans l�ENV 1591-2.
Ces modes opératoires d�essai peuvent être appliqués à des joints de formes et de dimensions différentes
mais cela doit être indiqué dans le compte rendu.
Les joints entièrement fabriqués en matériaux élastomères ou fabriqués à partir de matériaux élastomères
additionnés de charges particulaires ou de renforts sous forme de particules, ne relèvent pas du domaine
d�application du présent document.
