ASTM D6078
Fully Automatic Laboratory Instrument For Evaluating The Scuffing Load Resistance Of Diesel (Middle Distillate) Fuel
Model：JF6078
Product Introduction
This instrument is a fully automatic laboratory instrument, suitable for lubricity testing of diesel (middle distillate) fuel. It fully complies with the requirements of ASTM D-6078 "Standard Test Method for Evaluating the Lubricity of Diesel Fuel by Wear Loaded Ball Cylinder Lubricity Evaluator". The instrument uses a submerged ball-to-cylinder contact geometry. Since the onset of wear is characterized by a sudden increase in friction between the two contact bodies, the load sensor is incorporated into the load arm assembly. This can measure the tangential friction between the rotating disk and the stationary ball.

Features
Microprocessor control of all instrument functions;
Simple user interface. Instrument functions can be upgraded by downloading new firmware;
Both the standard ASTM D6078 test sequences (Procedure A and B) come pre-loaded into microprocessor controller;
Automatic control of whole test sequence;
No operator-induced variability in test results;
Automatic flow controllers for moist and dry air;
No operator input needed to set the humidity and flow rate of the conditioned air;
Optional PC-based control and data logging software;
Allows alternative test programmes to be downloaded into instrument, and test parameters to be recorded as a permanent record;
Humidity and temperature measurement does not need to be re-calibrated – simply exchange the combined relative humidity and temperature probe for a precalibrated unit;
Single source of supply for both the test rings and test equipment.
