What is BS EN 1337-2 - Sliding elements and guides about?
BS EN 1337-2 is the second part of the BS EN 1337 multi-series that discusses structural bearings.
BS EN 1337-2 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 BS EN 1337.
Note1: 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 BS EN 1337-2.
Note2: Sliding elements for use as temporary devices during construction, for example during the launching of the superstructure, are also outside the scope of BS EN 1337-2.
Who is BS EN 1337-2 - Sliding elements and guides for?
BS EN 1337-2 on sliding elements for structural bearings is useful for:
- Civil engineers
- Manufacturers of structural bearings
- Architects
Why should you use BS EN 1337-2 - Sliding elements and guides?
Sliding elements and guides permit movements in plane or curved sliding surfaces with a minimum of friction. Specific verification of frictional resistance is required, as verification of mechanical and physical properties alone is not sufficient to ensure that these components will have the required characteristics.
BS EN 1337-2 informs you of the mechanical properties and functional requirements necessary for sliding elements. BS EN 1337-2 provides you with design requirements and dimension tolerances for sliding elements. BS EN 1337-2 also helps you perform test methods to verify that these requirements are met. BS EN 1337-2 also describes the method for determining the coefficient of friction of the sliding surfaces.
Overall, the guidelines of BS EN 1337-2 enable you to produce or incorporate quality sliding elements and guides with suitable frictional resistance for bridge-building projects.
