HFRR (High Frequency Reciprocating Rig)


HFRR methods are used worldwide to test the lubricity of fuels. The HFRR test is mentioned in diesel specification directives EN 590, D975 and JIS 2204.


The HFRR lower and upper specimen can be used in diesel, domestic fuel oil, KERO, light component fractions, LGO, GTL, HVO with HFRR methods ISO 12156-­1, ASTM 6078/6079, ASTM 688, IP450, CEC-­F-­06-­A, JPI 5S­50.


Rodali offers HFRR lower and upper specimen.Every box of HFRR lower specimen is tested with HFRR reference fuels. In addition, every box is tested on roughness and surface control by microscope is performed. Every box includes a HFRR specimen certificate.


The upper HFRR specimen are certified and have their own batch number specifications.

CFPP (Cold Filter Plugging Point)


CFPP parts are used for diesel, domestic fuel oil, MGO, KERO, LGO HGO, GTL, HVO and FAME (biodiesel) with CFPP methods EN116, NEN­ EN 16329, IP309, ASTM D6371, JIS K2288 en DIN­ EN 14214. The CFPP test method is mentioned in diesel specification directives. For the US these are D975, for Japan JIS K2204 and for Europe EN590.


The latest CFPP method is described in NEN-EN-16329-2013, which is now mentioned in EN590 as well.


The method recommends to use specific CFPP parts, since both 100% FAME (bio diesel) and Bx diesel blends that contain FAME can harm the CFPP parts. FAME is a collective term for methyl esthers, such as RME, PME, SME, TME, UKO and HVO.


These specifically manufactured CFPP 45 μm sieves and filter units are now sold by Rodali to protect them against corrosion or damage.
