24、at Dec 30 06:33:53 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Page 4 EN 1337-2:2000 Introduction This standard considers a minimum operating temperature of 35C. An extension down to 40C will be considered in a future amendment. Applications beyond the range of temperature given in clause 1 need spec
25、ial consideration not covered by this standard. Characteristics and requirements given in this standard do not apply in such cases. 1Scope This European Standard specifies the characteristics for the design and manufacture of sliding elements and guides which are not structural bearings but only par
26、ts 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
27、mm, or with effective bearing temperatures less than 35C or greater than 48C 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. I
28、n 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 e
29、lements outside this scope, but their suitability for the intended use should be proven. 2Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the pu
30、blications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including
