HFRR Test Specimens

Research has shown that the High frequency reciprocating rig (HFRR) test is the best test to accurately measure diesel fuel lubrication. Upper specimens and lower specimens are produced by FenixES. FenixES high frequency reciprocating rig ( HFRR ) specimens meeting the requirements of ISO 12156-1, ASTM D6079, ASTM D7688 and IP450 diesel test standards.

Our high frequency reciprocating rig (HFRR) specimens are actively used in SGS laboratories, SOCAR Star Refinery, Middle East Technical University Petroleum research laboratory and EGE Petroleum research laboratory.

Our HFRR test specimen can be produced desires sizes.
