High Frequency Reciprocating Rig (HFRR)


ASTM D 6079-97, EN 590, IP 450 / 2000, BS – ISO 12156 – 1, JPI – 58 – 50 -98, CEC F 06 A96


The purpose of this tester is to characterize friction under lubricated condition using a ball on disc configuration. This tester is particularly suited for evaluating low lubricity fluids like diesel and gasoline.


The system consists of a temperature controlled stage that houses the test plate. A reciprocating arm with a ball holder to hold the test ball is pressed against the test plate with a known force. The system reciprocates maintaining the required stroke length, frequency, load, temperature and humidity.


A piezoelectric force transducer senses the frictional force. The unit is computer controlled and uses the WinDucom Data Acquisition System to record the output parameters.
