OIL ANALYSIS TESTS

Flash Point - Go-No-Go

This test is used to determine the closed cup flash point by the go/no go method using the Setaflash Tester in the temperature range of 30oC to 300oC.

Fuel contamination of lubricating oils is a potential hazard. Even a small dilution can radically reduce viscosity and flash point, with serious consequences. Measuring the flash point is a sensitive test to determine the presence of fuel. In piston engines it may be a sign of injection pump wear, blocked injectors or inefficient combustion or cracked / broken fuel return lines, whereby unburnt fuel is deposited on the cylinder walls and mixes with the lubricating oil. In some turbines the fuel is heated by the oil, any leak in the heat exchanger will force fuel into the oil with potentially damaging consequences. Initially the oils are flashed at a screening temperature dependant on application.
