TASS Verification System
The Torque Angle Slip Standard (TASS) by Bosch Rexroth tests your tightening tools to ensure they meet safety-critical standards. The TASS element attaches to your tightening tool and processes results in a characteristic curve. This data is then compared with the nominal characteristic curve of the mechanical element; this comparison allows the TASS to detect possible deviations.
TASS Structure
- The TASS element is clamped in the test device in a form- or force-fit manner.
- The torsion shaft in the body acts as a dimensional standard with a defined torque/rotation angle curve.
- Every TASS element comes with certified documents that prove its measuring points, rotation angle, and linearity deviation.
- Five TASS sizes cover torque ranges from 1Nm to 600Nm
Test Arrangement
- The tightening system stays in the production environment during the test.
- The nutrunner performs a fitting with a certain rotation angle and low tightening velocity.
- The tool records the process data as it does with a regular tightening case.
- The TASS element compares the data to the nominal curve to determine if the measurement of the tightening system is OK.
