The HFRR is a microprocessor-controlled reciprocating friction and wear test system which provides a fast, repeatable assessment of the performance of fuels and lubricants.

The 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 like diesel fuels and for boundary friction measurements of engine oils, greases and other compounds.

The HFRR test for diesel fuel lubricity gained CEC "A" status in September 1996 after an extensive round-robin program. Other standards based on the HFRR system include ASTM D6079-97, ISO 12156-1, ISO 12156-2,
EN 590:1998, JPI-5S-50-9 and IP 450/2000.

The control unit includes a key pad, LCD display and a built in microprocessor so that the complete test cycle can be automatically controlled directly from the unit. Alternatively the control unit can be connected to a PC through a single serial connector to allow data logging, graphical representation and output file storage as with the previous HFRR system. The new unit also includes a humidity probe option, the output from which is automatically logged at the beginning and end of test according to the CEC test method.

Key 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.
• Automatic recording of humidity and air temperature at start and finish of test using built in digital humidity probe.
• Calculates WS1.4 where necessary.

Developed in consultation with a major fuel additive manufacturer and the Tribology Laboratory of Imperial College, London, there are currently over 600 systems in use in more than 40 countries world-wide.
