HFR2    High Frequency Reciprocating Rig
The HFR2 is a computer-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. Developed in consultation with a major fuel additive manufacturer and the Tribology Laboratory of Imperial College, London, there are currently over 350 systems in use in more than 40 countries world-wide.

The use of small, inexpensive specimens with many possible configurations means that specimens can be chosen to duplicate in-service conditions. Good repeatability and reproducibility. 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, computer controlled test sequence. Easy to calibrate. Compact, quiet bench top system.
