Railway infrastructure — Rail fastening systems — Part 7: Test method for clamping force and uplift stiffness
Preview
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
ballastless 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 which do not act on the foot of the rail.
