A fully automatic laboratory instrument for evaluating the scuffing load resistance of diesel (middle distillate) fuel according to ASTM D6078.
PCS Instruments’ ABSSL System (Automated BOCLE System Scuffing Load) is a fully automatic laboratory instrument for carrying out lubricity testing of diesel (middle distillate) fuel. It fully conforms to the requirements of ASTM D-6078 “Standard Test Method for Evaluating Lubricity of Diesel Fuels by the Scuffing Load Ball-on-Cylinder Lubricity Evaluator (SLBOCLE)”.
The standard PCS ABS test equipment can be modified to allow the SL-BOCLE tests to be carried out. Alternatively, the ABSSL test equipment can be supplied as new.
As with the standard BOCLE test, the instrument utilises a flooded, Ball-on-Cylinder contact geometry. Since the onset of scuffing is characterised by a sudden rise in the friction force between two contacting bodies, a load cell is incorporated into the load arm assembly. This is able to measure the tangential friction force between the rotating disc and stationary ball.
