The High Frequency Reciprocating Rig (HFRR) was designed by Prof. Hugh Spikes at the Department of Mechanical Engineering, Imperial College, London. Like the SRV, the HFRR also utilizes a ball-on-disk configuration.
The HFRR uses an electromagnetic vibrator to oscillate the top specimen (ball) on the fixed bottom specimen (cylinder), which is held in a small bath. An electrical heater controls the temperature of the test lubricant/fuel in the bath. Both the friction force transmitted between the specimens and the electrical contact resistance (ECR) is measured. Measurement of the wear scar on the top specimen is used to quantify the lubrication of the sample.
The HFRR has been included in the European diesel standard EN 590, which utilizes the ISO12156 (2003) method and also in the American diesel standard ASTM D975 (2004) which utilizes the ASTM D6079 (2005) method.

Documentation
HFRR Installation & Test Preparation Manuals
Downloadable versions of the manuals provided by PCS Instruments are available.
HFRR Installation Manual is available here
HFRR Test Preparation Manual is available here
Standards
The most updated versions of ASTM D6079 and ISO12156 can be found here. The Tribology Lab uses the ISO method, but the standards are very similar.
Test Procedure
The HFRR test procedure was compiled by Rucu Maree in January 2010.
