Koehler – Tribology – ATF Lubricity Test Rig (BOCLE)
Covers the Assessment of the wear aspects of the boundary lubrication properties of aviation turbine fuels on rubbing steel surfaces. The test ball is pressed with a force of 10 N against the test ring. The test ring is made to rotate at 240 RPM for a period of 30 minutes after which the test stops.
The wear scar on the test ball is studied and the scar diameters of the wear scar (major and minor axis) are measured. Data Acquisition Test parameters such as speed, test duration, fuel temperature, air temperature and humidity are acquired, displayed and recorded. The acquired data can be viewed in graphs. The data acquisition system provides the users with the facility to super impose up to four test graphs for comparative viewing.

Key Features
ATF Lubricity Test Rig (BOCLE)
- Simple to use interface –digitally computer control of all instrument functions
- Standard ASTM D 5001 test sequence pre-loaded into ABT microprocessor controller – operator fits cleaned specimens, adds fuel sample, and presses the ‘Start Test’ button
- Automatic control of test sequence-no operator-included variability in test results
- Automatic flow controllers for moist and dry air-no operator input required to control the humidity and flow rate of the conditioned air
- PC based data logging of Motor speed, test duration, fuel temperature, air temperature, humidity recorded during the test and a summary printed out confirming that all parameters were within the specified limits
- Interchangeable humidity and temperature probes-humidity and temperature measurement does not need to be re-calibrated-simply replace the combined relative humidity and temperature probe with an exchange pre-calibrated unit
- Heating and Cooling System through Peltier Heating and Cooling System
- Digital Microscope with Image Acquisition System and software
- PC based data acquisition and analyze system of motor speed, test duration, fuel temperature, air temperature, humidity
