9.2.4 Air introduction into the measuring chamber
To have enough oxygen for each arc to develop a flame, a small amount of air is introduced into the measuring
chamber after each ignition. This is especially important for heavily fuming samples and also simulates
standardized closed cup methods where the measuring chamber is opened to introduce the flame or glowing
wire.
9.2.5 Flash point detection
The measuring procedure is continued until the pressure increase after an arc exceeds the programmed
threshold.
9.2.6 End of test
After detection of a flash point or reaching the final temperature the measurement is stopped and the oven is
cooled down fast to the starting temperature Ti.
The sample cup is lowered automatically when the temperature of the oven is at Ti-(Ti-T).
