Abstract:
The flash point of an organic liquid is defined as the lowest temperature at which the vapors formed above the liquid will briefly ignite in close proximity to an ignition source. Determination of the flash point is crucial to ensuring safety in the petroleum industry when considering the proper environment for the storage and transportation volatile substances. Regarding oils, a comparison between the baseline flash point of an oil and the flash point of a separate sample of the oil can be utilized for a variety of analyses, such as changes in oil chemistry (oil cracking), additions to the oil (oil contamination), or subtractions from the oil (thermal evaporation). The primary testing methods for flash point determination are classified as either open or closed cup tests. Since the measured value for the flash point can vary depending on the distance from the ignition source, closed cup tests are typically preferred, as the resultant flash points will typically be lower, erring on the side of caution. The K71000 Automatic PMCC Flash Point Analyzer manufactured by Koehler Instrument Company, Inc. is a fully automatic flash point tester that can determine the flash points of flammable substances via the Pensky-Martens Closed Cup Test, as specified in ASTM D93.
