The Technical Test Specifications for Skid Resistance Measurements in Road Construction, TP Griff-StB (SRT), stipulate control facilities in the form of calibration bodies for the functional testing and calibration of the skid resistance measuring devices "SRT pendulum device" and "Moore outflow meter". The Institut für Straßenwesen is an independent calibration body certified by the Bundesanstalt für Straßenwesen (BASt) and issues the time-limited operating permit required in accordance with the technical test specifications.
The calibration laboratory offers the following services:
- TP Handle-StB conform calibration,
- Maintenance of the measuring instruments,
- Complete functional test,
- Repair work as well
- Replacement of worn or defective parts.
The calibration of the measuring instruments is carried out with the highest precision, whereby each individual measuring instrument is disassembled into its mechanical functional units and subjected to extensive maintenance and complete functional testing. The availability of special measuring instruments, among other things for characterizing the rubber-specific characteristics of the measuring rubbers, contributes to ensuring the quality of the measuring equipment used.
Furthermore, the availability of a wide range of original English spare parts ensures a quick exchange of worn or defective parts as well as a quick repair of damaged measuring instruments.
The personnel specifically trained by BASt for the calibration of the measuring instruments and the many years of experience in the field of skid resistance measurement at the institute guarantee the necessary technical competence.
In addition to the professional calibration of the measuring instruments, the institute also has contacts for interdisciplinary questions and advice, especially in connection with the materials testing laboratory.
