23、Foreword This document (EN 1337-3:2005) has been prepared by Technical Committee CEN/TC 167 “Structural bearings”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the la

24、test by September 2005, and conflicting national standards shall be withdrawn at the latest by December 2006. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For r

25、elationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This European Standard EN 1337: “Structural bearings” consists of the following 11 parts: Part 1 General design rules Part 2 Sliding elements Part 3 Elastomeric bearings Part 4 Roller bearings Par

29、eld of use such as flat sliding elements covered by EN 1337-2 or sliding surface described in 4.4.4, as used in bridge structures or any other structure with comparable support conditions. This part of EN 1337 applies to elastomeric bearings with dimensions in plan up to (1200 x 1200) mm and does no

30、t cover elastomeric bearings made with other elastomers materials than those specified in 4.4.1. It applies to laminated bearings types A, B, C, laminated sliding bearings types E and D, plain pad and strip bearings type F. This part deals with bearings for use in operating temperatures ranging from

31、 25 C to + 50 C and for short periods up to + 70 C. It is recognised that the air temperature in some regions of Northern Europe is lower than 25 C. In this case of very low operating temperature (down to 40 C), it is essential that bearing characteristics comply also with the shear modulus at very
