Characterization and Fingerprinting of Fresh Lubricating Oils

Ensuring Fresh Lubricants Meet Quality and Compliance Standards

A comprehensive evaluation of unused lubricants ensures product integrity, formulation accuracy, and compliance with UAE and GCC regulatory standards. Fresh oil fingerprinting supports COA issuance, SASO certification, and GSO 1785 conformity—protecting equipment from the very first use. 

Content 

Fresh lubricating oils undergo detailed analysis before entering service to verify their quality and ensure they meet required specifications. This process establishes a complete fingerprint of the lubricant, confirming that it is clean, stable, and compliant with regional standards. By validating unused oils at the outset, organizations strengthen their quality assurance programs and support long‑term equipment reliability. 

Key Parameters Included in Fresh Lubricant Analysis 

Visual Inspection 

  • Color & Clarity (ASTM D1500)

Physical Properties 

  • Kinematic Viscosity @ 40°C & 100°C (ASTM D445)
  • Viscosity Index (ASTM D2270)
  • Flash Point (ASTM D92)
  • Pour Point (ASTM D97) 

Chemical Stability 

  • Total Base Number – TBN (ASTM D2896 / D4739)
  • Total Acid Number – TAN (ASTM D664)
  • Noack Volatility (ASTM D5800) 

Additive Elemental Analysis (ICP) 

  • Zn, P, Ca, B, Mo, Mg, Ba, Na, Si, Sn, Sb, Mn, Fe, Cu, Pb, Ni, Al 

Cleanliness & Contamination 

  • Particle Count (ISO 4406)
  • ISO Code Classification
  • Demulsibility (ASTM D1401)
  • Copper Corrosion (ASTM D130) 

Regional Compliance 

  • GSO 1785‑1/2
  • SASO Lubricant Quality Mark
  • UAE MOIAT / ESMA conformity 

This consolidated parameter set ensures that fresh lubricants meet the required quality, performance, and regulatory standards before being released to the market or introduced into equipment. Establishing this baseline supports COA documentation, enhances reliability programs, and ensures consistent product performance across industrial applications.
