Automatic Lubricity Tester (BOCLE)

Determines the wear aspects of the boundary lubrication properties of aviation turbine fuels on rubbing steel surfaces.

• 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 & 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 & a summary printed out confirming that all parameters were within the specified limits.

• Interchangeable humidity & 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 & Cooling System through Peltier Heating & Cooling System

• Digital Microscope with Image Acquisition System & software

• PC based data acquisition & analyze system of motor speed, test duration, fuel temperature, air temperature, humidity.

• Ultrasonic Cleaner

High Frequency Reciprocating Rig (HFRR))

For evaluation of the lubricity of diesel fuels using a high frequency
reciprocating rig (HFRR). A 2-mL test specimen of fuel is placed in the test reservoir and maintained at 25 or 60°C. When the temperature has stabilized, a vibrator arm holding a non-rotating steel ball and loaded with a 200-g mass is lowered until it contacts a test disk completely submerged in the fuel. The ball is caused to rub against the disk with a 1-mm stroke at a frequency of 50 Hz for 75 min. The ball is removed from the vibrator arm and cleaned. The dimensions of the major and minor axes of the wear scar are measured under magnification and recorded.

• Conforms to ASTM D6079 and related specifications

• Wear scar measurement through digital microscope and software

• Programmed test sequence for automated testing

• Proven repeatability and reproducibility

• Rigidly built dedicated table top rig
