Further to CEN/TC 167s decision Part 1 and Part 2 form a packag

18、e of standards and they come into force together, while the other parts come into force separately after the publication of Part 1 and Part 2. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Stand

19、ard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.Page 4 EN 1337-1:2000 1S c o p e This European Standard is applicable to structural bearings, whethe

20、r used in bridges or in other structures. This European Standard does not cover: a) bearings that transmit moments as a primary function;b) bearings that resist uplift;c) bearings for moving bridges;d) concrete hinges;e) seismic devices. Although it is not intended to regulate temporary bearings thi

21、s standard may be used as a guide in this case (temporary bearings are bearings used during construction or repair and maintenance of structures). NOTE 1: Although the specifications given in this European Standard are necessary, they are not sufficient in themselves for the overall design of the st

22、ructures and for the consideration of geotechnical aspects. See prEN 1337-2 to prEN 1337-8 for information relating to bearings for which specifications are laid down for certain ranges of temperature only. 2 Normative references This European Standard incorporates by dated or undated reference, pro
