The field test kits/stations consist of a suite of electronic and/or manual
oil test equipment covering tests for diesel engines, gas and steam turbines,
compressors, hydraulics, gearboxes, aviation lubes, fuel oils, and much more.
Please refer below to the tests you need to conduct and the chart to help
determine your best solution for testing.
Density - range: 800-1010 kg/m3 at 15°C in vacuum
Quality control of fuel oil purchase and delivery will produce major cost
savings. Density measurements are critical for confirming the correct
quantities and grades delivered. The combustion performance (CCAI) can be
estimated, and viscosities in cP can be converted to cSt. Densities are
corrected to standard reference conditions of 15°C in vacuum.
Viscosity - range: 15-810 cSt at 40 and 50°C
Viscosity is the prime quality of fuel and lube oils, and is used to confirm
fuel grade and estimate combustion performance. It is fundamental to
maintaining the integrity of a lube oil film, preventing metallic contact,
scuffing, microwelding, and wear of sliding surfaces. Viscosity can increase
due to insolubles, oxidation, or water contamination, and decrease with
distillate fuel contamination.
Three options are available:
1) Heated viscometer for accurately measuring viscosity in cSt of lube and
residual fuel oils at 40 and 50°C, and predicting viscosity at 100°C.
2) Unheated viscometer for lube oil will accurately predict viscosity at
40°C. Test time is less than 2 minutes! (15-500 cSt at 40°C)
3) Viscosity stick for a comparative assessment of new and used oil
Compatibility - range: as per ASTM D4740
Mixing residual fuel oils can cause precipitation of asphaltenes leading to
blockage of filters and purifiers, resulting in serious combustion problems.
The compatibility test will determine fuel stability during storage, identify
possible stability problems before mixing fuels, and alert to possible sludge
formation before any failure to fuel handling systems and costly engine
Pour Point - range: -5 to 50°C
Pour point is a simple test and an indicator of the lowest temperature of
utility for fuel and lube oils. The lowest temperature at which movement of
the sample is observed is recorded as the pour point. Used to predict the
need for heating fuels in storage and supplied free with the Fuel & Lube
Oil and Power Plant Laboratory.
Salt Water - range: pass/fail
Salt water cannot be tolerated in fuel or lubricating oils. The presence of
salt will cause severe and rapid corrosion in any lubricating oil, fuel, and
hydraulic system. This simple test provides a pass/fail indication of salt
contamination in any system.
Water in Oil - range: 0-6000 ppm to 15%
Water is present in every lube oil and fuel system and originates from many
sources. High water levels increase oil viscosity, catalyze system corrosion,
promote cavitation, and cause instability of the lubricant additive package.
Water contamination represents a direct financial loss, potential corrosion,
and microbiological growth problems. Two testing options are available:
1) 0-1.2% or 0-15% test using a manually operated test cell.
2) 0-2.5% and 0-6000 ppm test using an electronically operated test cell.
Total Base Number (TBN) - range: 0-50 mg KOH
The TBN of an oil is the measure of the alkaline reserve or the ability of
the oil to neutralize acids formed during combustion. Severe TBN depletion
will lead to acidic corrosion and fouling in diesel engine systems.
Additionally, low TBN is indicative of reduced oil detergency.
Total Acid Number (TAN) - range: 0-6 mg KOH
The TAN of an oil is the measure of the acids present in an oil (some are
additives!). All oils will slowly oxidize during use, which can be
accelerated by high operating temperatures or hydrolysis of synthetic
lubricants. High TAN is indicative of oil oxidation and is often accompanied
by viscosity increase, formation of lacquers, and acidic attack of mechanical
components. Monitoring TAN in aviation, gas engine, turbine and gear systems
provides a good indication of system conditions and remaining oil life.
Insolubles - range: 0-3.5%
Insolubles build up in engine oils from carbon, dust, spent additives,
oxidation products, and wear debris. High levels of insolubles cause wear and
fouling. This test provides an indication of insolubles levels in lubricants.
Two options are available:
1. A manual test for basis pass/fail type indication
2. An electronic test for very accurate quantitative readings.
