CONSTANTIN GEORGESCU, GEORGE CATALIN CRISTEA, CATALIN LIVIU SOLEA, LORENA DELEANU, IOAN GABRIEL SANDU FLAMMABILITY OF SOME VEGETAL OILS ON HOT SURFACE Vegetal oils could be a solution to replace mineral oils, but their atypical behavior constrains users to test them. Tests on hot surface were done with the help of an original test equipment. The method is designed to imitate the worst scenario that could happen when fluid leakage reaches hot surfaces. The ignition temperature on hot surface for the tested vegetal oils is in a narrow range (495...510oC), higher than most mineral oils, this being due to the similar composition in fat acids.
