Calibration Lab

 

Enshrined in the technical test specifications for skid-resisting property measurements in road construction, TP grip StB (SRT), are control authorities in the form of Calibration Labs for the functional test and calibration of the grip traction measuring instruments "SRT-Pendulum device" and "outflow meters after Moore".

So far the calibration of these measuring instruments was accomplished exclusively by the Federal Highway Research Institute (BASt). Since the beginning of 2008, this task has been transferred to two independent calibration authorities certified by the BASt.
As one of these two places the Institute of Road and Traffic Engineering Aachen, at RWTH Aachen University, is with immediate effect responsible for the execution of the calibration and grants the time-limited operating approval necessary in accordance with the technical test specifications.

 

Description of services:


The calibration service offers the following services:

  • TP Handle StB compliant calibration,
  • Maintenance of measuring instruments,
  • Complete functional check,
  • Repair work as well
  • Replacement of worn or defective parts.

The calibration of the measuring instruments is carried out with exact precision, whereby each individual measuring instrument is disassembled into its mechanical functional units and undergoes extensive maintenance as well as complete functional testing.
The availability of special measuring instruments, including the characterization of the rubber-specific characteristic values ​​of the measuring gums, contributes to the quality of the measuring instruments used.
Furthermore, the provision of a widely diversified spare parts program of the English original parts ensures a rapid exchange of worn or defective parts as well as a rapid repair of damaged measuring devices.

The teamfor the calibration of the measuring instruments wich is trained by the BASt, as well as the years of experience in the field of grip measurement at the institute ensure the necessary professional competence.
In addition to the professional calibration of the measuring instruments, the institute, in particular in connection with the material testing department, also provides contact persons for interdisciplinary questions and advice.
