It should be noted that, in Germany, CE conformity marking of construction products will be permitted once this standard has been listed in the Bundesanzeiger (German Feder
4、al Law Gazette) and from the date given therein. National foreword This standard has been prepared by CEN/TC 167 “Structural bearings” (Secretariat: UNI, Italy). The responsible German body involved in its preparation was the Normenausschuss Bauwesen (Building and Civil Engineering Standards Committ
5、ee), Technical Committee NA 005-57-02 AA Lager im Bauwesen (DIN 4141) (Sp CEN/TC 167 Structural Bearings). Amendments This standard differs from DIN V 4141-13:1994-10 as follows: a) In this standard Group 2 guide bearings are specified regardless of the magnitude of the actions. b) The contents of t
6、his standard have been harmonized with the relevant provisions regarding CE marking and labelling of construction products. c) Specifications have been modified so that they are based solely on the semiprobabilistic approach using partial safety factors.

DIN EN 1337-8:2008-01 EN 1337-8:2007 (E) 5 1 Scope This Part of this European Standard deals with the requirements for the design and manufacture of Guide Bearings and Restraint Bearings. Guide Bearings and
26、Restraint Bearings are not intended to transmit vertical loads but they may be combined in one unit with bearings in accordance. EN 1337-1:2000, Table 1. NOTE 1 Guide Bearings and Restraint Bearings are shown in EN 1337-1:2000, Table 1, No. 8.1 and 8.2. For combined bearings see EN 1337-1:2000, Tabl
27、e 1, bearing Nos. 1.2, 1.3, 1.6, 1.7, 1.8., 3.1, 4.1, 4.2, 4.3, 7.1, 7.3, and 7.4 with restraints and Nos. 1.5, 1.7, 2.2, 3.3, 3.4, 5.2, 6.2 and 7.3 with guides. NOTE 2 Examples of combined bearings are given in Annex B. The minimum operating temperature depends on the materials properties used at t
28、he required temperature and the limitations given in the referenced parts of this European Standard. NOTE 3 In certain circumstances the bearings described in this part of this European Standard may be required to operate in a plane inclined to the horizontal. In such circumstances the terms “vertic
29、al“ and “horizontal“ should be interpreted appropriately. 2 Normative references The following referenced documents are indispensable for the application of this document.
