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.
