The book entitled "Evaluation of lubricant properties" is structured in 2 chapters. Chapter one is entitled evaluation of lubricant properties in which we included evaluation of anti-wear and extreme pressure characteristics, evaluation of surfactant properties, emulsification, detergent and dispersant, evaluation of the behavior of lubricants at low and high temperatures, evaluation of the flammability characteristics of lubricants, concepts and tests involving fire or ignition of fluids, tests on the ignition of spray fluids, tests on ignition of fluid-soaked materials, tests regarding the ignition of flammable vapors (point de ignition) and tests to determine the flammability characteristics a fluids on hot surfaces. The second chapter presents flammability testing of vegetable oils on hot surfaces.
