Thanks for the info EGT01...i think at this point, I will send out the sample to a different lab as a sanity check and also go over my old chemical thermodynamics book again. This is vexing, especially if the flashpoint determination from the first lab is correct...it would require appropriate...
by the way, I am not a student (although this may sound like a homework problem)...the reason I am asking is because a sample of what we believe is 5% IPA was sent out for flashpoint determination and the results were 54 and 56 degrees fahrenheit. This does not sound right.
