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 CEC F-06-A-96 HFRR test for diesel fuel lubricity was finalized in September 1996 after an extensive round-robin program.
Other standards based on the HFRR system include ASTM D6079, 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.
An optional PC and software is available for data logging, graphical representation and output file storage.
The new unit also includes a humidity/temperature probe option.
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.
