Common Lubricant tests Water content IP 356 (KF) / ASTM D 1744 & 4377 • Measures extend of water contamination • In general “no water” should be present in lubricating oil ( Max tolerated is 0.2%) • Salt water contamination (Marine grades) may be traced to cooler leakages, ship’s hull etc.. • Common metals in sea water include • Sodium 11,000 ppm, Calcium 400 ppm, • Magnesium 1,300, Potassium 400 ppm Hussam Adeni Lube.specialist@gmail.com
Common Lubricant tests Total insolubles IP 316 / ASTM D 893 • Total amount of extraneous matter which are derived from products of combustion • Includes burnt lubricating oil and additive ash, rust, salt, wear debris and abrasive matter. (IP method deploys high RPM centrifuge +10,000 g, preferred for dispersant/detergent additives lube oils- ASTM D893 is 600 – 700 g) • Viscosity of an oil increase with increase in the level of total insolubles. • Expressed as % of the quantity of oil.
