Railway applications - Track - Test methods for fastening systems - Part 7: Determination of clamping force and uplift stiffness
Publication date
93.100 Construction of railways
Summary :
This document specifies the laboratory test procedure for determining the clamping force exerted by the fastening system on the foot of the rail by measuring the force to separate the rail foot from its immediate support. When required, the procedure is also used to determine the uplift stiffness of the fastening system. It is applicable to systems with and without baseplates on all types of sleepers, bearers or elements of slab track. The test does not determine the security of the fastening components fixed into the sleeper or other fastening system support. This test procedure applies to a complete fastening assembly. It is not applicable to fastening systems for embedded rail or other fastening systems that do not act on the foot of the rail.
