Railway applications - Track - Test methods for fastening systems - Part 2: Determination of torsional resistance
This European Standard specifies a laboratory test procedure to determine the moment necessary to rotate a rail, secured to a sleeper by a rail fastening assembly, through 1° in a plane parallel to the base of the rail. The value obtained can be used in track stability calculations.The test is not applicable to embedded rails.This test procedure applies to a complete fastening assembly.
