Railway Infrastructure - Rail Fastening Systems - Part 7: Test Method for Clamping Force and Uplift Stiffness
Also Known As:
ISO 22074-7:2021 standard outlines the laboratory test procedure for measuring the clamping force exerted by a rail fastening system on the foot of the rail. The procedure also includes the measurement of uplift stiffness if required.
The standard is applicable to both systems with and without baseplates, and it can be used for all types of sleepers, bearers, or elements of ballastless track. However, it should be noted that this test does not assess the security of the fastening components fixed into the sleeper or other fastening system support.
The test procedure described in ISO 22074-7:2021 is specifically designed for complete fastening assemblies and is not suitable for fastening systems that act on the rail foot. It does not apply to fastening systems for embedded rail or other types of fastening systems that do not directly interact with the rail foot.
