Lubricating Oil Test
7 Catalytic Fines Catalytic fines are a contaminant sometimes found
in residual grades of fuel, they are extremely
abrasive to steel. This test detects the presence of
any abrasive particles in the test sample -
whether they are catalytic fines, grit, sand, dirt, rust, etc.
8 Sludge/ Wax The formation of sludge in oils can cause problems
such as blocked filters. This test can indicate
the likely cause of the sludge formation and the
appropriate action to be taken.
9 Strong Acid Strong acid are extremely corrosive to steel,
the more so in the presence of water and salt.
This test allows an easy means of verifying that no
strong acid is present.
10 Comparative
One of the most fundamental changes to affect a lubricant
is a change in viscosity. These changes can be detected
on the spot with this test, to enable suitable remedial
action to be put in place before any potentially
costly damage ensues..
11 TBN The Total Base Number of an in-service lubricating
oil is a measure of the amount of alkalinity reserve.
This test allows staff to monitor the situation
independently of shoreside facilities and take
appropriate action in good time.
12 Insolubles This test quantifies the amount of the extraneous
material in the oil, relating the result to a
suitable course of action..
Microbiological Test
13 Microbes These tests are for detecting microbiological activity
in distillate fuels and lubricating oils. The tests
identify: Bacteria, Fuel degraders, Fungi and Sulphate
reducing bacteria.
