Structural bearings - Part 2: Sliding elements

This European Standard specifies the characteristics for the design and manufacture of sliding elements and guides which are not structural bearings but only parts of them for combination with structural bearings as defined in other Parts of this European Standard.
Suitable combinations are shown in Table 1 of EN 1337-1:2000.
Sliding surfaces with a diameter of the circumscribing circle of single or multiple PTFE sheets less than 75 mm or greater than 1500 mm, or with effective bearing temperatures less than -35°C or greater than 48°C are outside the scope of this European Standard.
Sliding elements for use as temporary devices during construction, for example during launching of the superstructure, are also outside the scope of this European Standard.
In this standard the specification is also given for curved sliding surfaces which are not part of separate sliding elements but which are incorporated in cylindrical or spherical PTFE bearings as per EN 1337.
NOTE     The general principles detailed in this European Standard may be applied for sliding elements outside this scope, but their suitability for the intended use should be proven.

Lager im Bauwesen - Teil 2: Gleitteile

Diese Europäische Norm legt Angaben für Bemessung und Herstellung von Gleitteilen und Führungen fest, die keine Lager, sondern nur Teile von solchen sind, für die Kombination mit Lagern, die in anderen Teilen dieser Norm geregelt sind.
Geeignete Kombinationen sind in EN 1337-1:2000, Tabelle 1 angegeben.
Gleitflächen aus ein- oder mehrteiligen PTFE-Platten, deren umschreibender Kreis einen Durchmesser von weniger als 75 mm oder mehr als 1500 mm hat oder deren wirksame Lagertemperatur niedriger als - 35 °C oder höher als 48 °C ist, liegen außerhalb des Anwendungsbereichs dieser Norm.
Gleitelemente, die vorübergehend als Hilfslager während der Bauphase dienen (z. B. beim Taktschieben des Überbaus), liegen außerhalb des Anwendungsbereichs dieser Norm.
In dieser Norm sind auch Angaben für gekrümmte Gleitflächen enthalten, die nicht Teile von separaten Gleitteilen sind, sondern die in Kalotten- und Zylinderlagern nach EN 1337-7 eingebaut werden.
ANMERKUNG   Die in dieser Europäischen Norm beschriebenen Grundsätze dürfen für Gleitelemente angewendet werden, die außerhalb dieses Anwendungsbereiches liegen, jedoch ist deren Brauchbarkeit für den vorgeschriebenen Verwendungszweck nachzuweisen.

As this could endanger the long term fitness for use of the sliding element,this condition is considered serviceability limit state.SIST EN 1337-2:2004
