Both the Ball On Cylinder Lybricity Evaluator (BOCLE) and the Scuffing Load - Ball On Cylinder Lubricity Evaluator work on the principle of testing the lubricity of a fuel/lubricant. A non-rotating ball is forced against a rotating cylinder. The cylinder is partially immersed in a bath of the fuel to allow the fuel to be constantly carried to the area of contact.

The BOCLE & SL-BOCLE machines operate on much the same principals. They are nearly identically constructed. They differ in: 1) The types of fuels they typically test. 2) The qualifying parameters and test methods (See ASTM link below). 3) The maximum load they can carry.

In this Table some basic differences are presented:

History of this Equipment

The equipment was recieved from Sasol in 2012 after being used there for a period of time. The equipment was conntected to the OPTO 22 network in 2012 by Jacques Langenhoven to allow data logging and control through the lab network and OPTO system.
