COC ASTM D92 IS FAIL TO TEST FLASH POINT

I'm sorry david, can you describe more detail about your statement "fail to get the result"?

Nurudin

Normaly, we can hear the sound "pi" & see ignition when the volatile liquid mixture in air at the temperature. But this time, it doesn't have the physical phenomenon.

David - what kind of instrument are you using? Does it use a flame or glow-plug type ignition? How is the flash observed, human eye or ionization ring?

Regardless whether the test is being run manually or automatically, what are you seeing (or not seeing) now that is different from when the test was operating properly? (Beyond just "it used to work, now it doesn't.)

Excess water will just hang around at the bottom or in emulsion and have little effect unless the flash point is >100C. At that point you will have a memorable experience...

We are using COC instrument, which is approval by gov, it's using a flame, and flash observed by eye. After analysis, we consider it was contamination by sea water.

If water contamination is suspecting,then confirm the same by ASTM D 95 method.Water may interfere the FP results.

Hello, I'm an electrical engeneer. And I'm working with trnasfomers, and i was hopeing someone could helpe me by describing this tet you are talking about, or giv me some kind of web page to find it, all i could find wuere paid ones... Cuz we work a lot with insulating oils in switchs and transformers.

LOL

Is it possible that you can dessicate the sample? 60 C for 3 days would be a nice treatment, however, you must bear in mind that it might interfere with some components of your lubricant. Centrifugation, perhaps, and then repeat the COC assay. And if it is salt water, i dont think that remaining salts, if any, interfere with the test.

Damian,
Through this link (http://www.google.com/search?q=flash+point+test&btnG=Search&hl=en&rls=com.microsoft%3Aen-US&sa=2) you can find more info than you want to know about Flash Point measurements.

did you do the correct operational operations? please ask me if you problems.
