Main product features
- Standard test for diesel fuel lubricity
- Wear scar assessment with the standard specimens requires only one measurement
- Only a small volume of lubricant is required – tests can be carried out on field collected or experimental fluids; film formation by boundary additives can be observed by electrical contact potential (ECR) changes
- Fast, repeatable friction and wear measurement
- Independently proven repeatability and reproducibility
- Fully automated microprocessor controlled test sequence
- Easy to calibrate
- Small, compact bench top system
- Available with mini-printer option or full computer controlled software
- Preloaded with standard diesel fuel lubricity test procedures CEC/ASTM/ISO
- Optional automatic recording of humidity and air temperature at start and finish of test using built in digital humidity probe
- Calculates WS1.4 where necessary

The High Frequency Reciprocating Rig (HFRR) is a microprocessor-controlled reciprocating friction and wear test system which provides a fast, repeatable assessment of the performance of fuels and lubricants. It is particularly suitable for wear testing relatively poor lubricants such as diesel fuels and for boundary friction measurements of engine oils, greases and other compounds. It has become the industry standard test for diesel fuel lubricity and conforms to ASTM D6079, ASTM D7688, CEC F-06-A, ISO 12156, EN 590, JPI-5S-50 and IP 450.
The system comprises a mechanical unit, control unit and optional PC software. The control unit includes a keypad, LCD display and a built in microprocessor so that the complete test cycle can be automatically controlled directly from the unit in standalone mode. Alternatively, the control unit can be connected to a PC to allow data logging, graphical representation of test parameters and results’ file storage.
The control unit is pre-set with ISO/ASTM/CEC profiles for performing standard diesel lubricity tests. The control unit displays the average film and friction of each test. The unit also includes a humidity probe option, the output from which is automatically logged at the beginning and end of the test in accordance with the CEC F-06-A test method. By manually inputting the X and Y wear scar readings, the unit will automatically calculate and display the WS1.4 value. For users who need a simple printed record of the test there is an optional mini printer which attaches to the control unit.
The HFRR is easy to calibrate and follows a fully automated test control sequence, freeing up operator time. Test specimens are a single use ball and disc which conform to all international diesel fuel test standards. Specimens in other materials and to different specifications are also available. Outside of diesel fuel testing, current HFRR applications include gasoline testing, measuring grease behaviour under boundary conditions, the evaluation of marine engine lubricants and investigations into fretting, both dry and in the presence of lubricants.
The new control unit is backwards compatible with all RTD mechanical units, enabling most current HFR2 users to upgrade their existing electronics unit if they choose.
