NBN EN 13146-7:2012

This European Standard specifies a laboratory test procedure for determining the clamping force exerted by the fastening system on the foot of a rail by measuring the force to separate the rail foot from its immediate support. It is applicable to systems with and without baseplates on all types of sleepers, bearers and elements of slab track. The test does not determine the security of 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.
