(Equivalent Test Methods: IP 34, ISO 2719, DIN 51758, JIS K 2265, and AFNOR M07-019)
EXPLANATION
This method is used for the analysis of fuel oils, lube oils, suspension of solids, liquids that tend to form a surface film under test conditions, and other liquids.
TEST SUMMARY
The sample is heated at a slow, constant rate with continual stirring. A small flame is directed into the cup at regular intervals with simultaneous interruption of stirring. The flash point is the lowest temperature at which the vapor above the sample ignites.
There are two procedures allowed which differ in their heating rate and the stirrer speed of the sample.
