Scope

This International Standard specifies a test method for the determination of the flash point of chemicals, lube oils, aviation turbine fuel, diesel fuel, diesel/biodiesel blends and other liquids by a continuously closed cup tester utilizing a specimen size of 2 ml, cup size of 7 ml, with a heating rate of 2.5 °C per minute. This flash point test method is a dynamic method and depends on definite rates of temperature increase. It is one of the many flash point test methods available and every flash point test method, including this one, is an empirical method. It utilises an electric arc as the ignitor and detects the flash point by pressure measurement.This test method is suitable for testing samples with a flash point from 22,5 °C to 235,5 °C. Flash point determinations below 22,5 °C and above 235,5 °C may be performed, but the precision has not been determined.
