* Physicochemical lubricants properties * Lubricants chemical degradation * Mechanical elements wear * Contamination Through the control of these parameters, the analyst has the necessary tools to be able to make the correct decisions in order to keep save the operative condition of machines lubrication system and increase lubrication quality. Types of analysis: • ISO Cleanness Code (ISO 4406)• Morphological analysis of wear particles • Microphotography 160x • Kinematics Viscosity (ASTM D 445) • Viscosity Index (ASTM D 2270) • Presence of Water through Karl Fischer Method (ASTM D 4928) • Total Acidity (TAN) (ASTM D 974) • Total Basic Number (TBN) • Determination of flash and fire points (ASTM D-92) • Foaming Characteristics and Air Release (ASTM D 892) • Potential of Hydrogen (pH) • Density (ASTM D 1298) • Oil dilution with gasoline fuel (ASTM D 322) • Detection of Copper Corrosion (ASTM D 130) • Scanning Electronic Microscopy - X-ray Fluorescence Spectrometry (SEM – EDAX) • Four-ball analysis of extreme pressure (ASTM D 2266, ASTM D 2596) • Infrared Spectrometry FTIR ASTM E2412 • Analytical Ferrography • Gas chromatography-mass spectrometry GC-MS (ASTM D 3514) • Wear Spectrometry – contamination – additivation (ICP – AES) (ASTM D 4951) • Water Demulsibility (ASTMD 1401) • Pour and cloud point • Aniline Point (ASTM D 611) • Interfacial Tension • Residual PCB content (ASTM D 4059) • Delta Tangent IEC – 247 • Dielectric Rigidity • Furan Content • Polymerization Degree • Conductivity (Standard methods 2510 C) – Specific for cooling water • pH (Standard methods 4500H+ - B) – Specific for cooling water • Total dissolved solids (Standard methods 2540A – G) – Specific for cooling water |
