Force measurement (contact pressure and
tangential force)
Temperature measurement in and on the
test object
Deformation measurement (laser)
Mechanical residual stress detection
Surface roughness
Hardness testing
Noise level
Crack testing (potential probe method)
Wear
Corresponding wheel profile measurement
Thermal imaging
Results
Presentation and evaluation of the
measurement results in accordance with
international standards, e.g. to audit
compliance with admissible coefficient of
friction deviation ranges or determine
braking power limits within the scope of
wheel homologation.
Expertise
Cooperation with International Union of
Railways (UIC) panels and in European
standardisation. Support in the creation of
test programs, and homogenisation and
advanced development of test methods.
