Filter Debris Analysis
Filter Debris Analysis
Used filter debris analysis using analytical ferrography, elemental spectroscopy, optical microscopy, chemical microscopy, etc.
Filter Performance Testing
Filter Performance Testing
ISO and SAE standardized filter performance testing (capture efficiency, dirt-holding capacity, application compatibility, fabrication integrity, etc.) using multi-pass test stands, single-pass test stands and others.
Oxidation Stability Testing
Oxidation Stability Testing
Thermal and oxidation stability testing (turbine oils, hydraulic fluids, gear oils, grease, etc.). Test methods include HP calorimetry, rotating pressure vessel oxidation test, turbine oil oxidation stability test, TFOUT, linear sweep voltametry, panel coker, sludge tendency and others.
Sludge and Varnish Testing
Sludge and Varnish Testing
Sludge, sediment, surface deposit and varnish analysis (combustion turbines, steam turbines, compressors, hydraulics, diesel engines, etc.) using membrane patch colorimetry, spectrophotometry, infrared spectroscopy, ultracentrifuge, solvent extraction methods, GC/MS and total insoluble.
Lubricant Water-Handling Ability
Lubricant Water-Handling Ability
Tests for demulsibility, hydrolytic stability and water-shedding ability for both oil and grease.
Air Handling Ability
Air Handling Ability
Tests for air content, air release, foam tendency, and foam stability. Typical applications are turbine oil, compressor fluids and hydraulic fluids.
Corrosion Suppression Tests
Corrosion Suppression Tests
Tests are offered for both lube oils and grease to assess the protection provided by the lubricant and additives to resist rust and corrosion of working machine surfaces. Tests include rust, copper strip, EMCOR, water spray and others.
Lubricant Physical Properties Analysis
Lubricant Physical Properties Analysis
Tests include viscometry, density, flash point, vapor pressure, volatility, bulk modulus, shear stability and many others.
Grease Physical Properties Analysis
Grease Physical Properties Analysis
These include mechanical stability, oil retention, shear stability, consistency (penetration), dropping point, pumpability, channel point and many others.
Lubricant Compatibility Analysis
Lubricant Compatibility Analysis
Tests evaluate various binary mixtures of lubricants to determine negative performance consequences from clashing additives, base oils and grease thickeners. ASTM test methods are used to assess compatibility.
Contamination Analysis
Contamination Analysis
Tests assess the presence of glycol, fuel, bacteria, water, particulates and others. Methods include elemental spectroscopy, infrared spectroscopy, particle counting, titration, flash point, GC/MS, optical microscopy, paper chromatography, ultracentrifuge, gravimetric analysis, X-ray fluorescence spectroscopy, pentane insoluble and chemical microscopy.
Film-Strength Studies
Film-Strength Studies
Tests utilize tribometers to assess friction and wear resistance of lubricants and mating surfaces. Common methods include four-ball, Timken, gamma Falex, pin-on-disc, FZG gear, vane pump, gear pump and numerous others.
Metallography and Wear Surface Topography Analysis
Metallography and Wear Surface Topography Analysis
Damage to machine surfaces can be interpreted to help reveal the root cause. Tribological methods are used to study the topographic and subsurface features of machine frictional surfaces to identify and characterize fluting, burnishing, scalloping, spalling, gray staining, ridging, galling, etching, scuffing, scoring, skidding, heat tinting, frosting and many other surface features.
On conventional way you can do patch test also
