Q:

What information is found on a flash point table?

A:

Quick Answer

Flash point tables generally contain information that identifies the liquid or liquids in question along with the flash points, fire points and auto ignition temperatures of the liquids shown. Flash point tables may also contain information or notes regarding the testing methods used to determine the temperatures stated in the table, the conditions under which testing was performed and anything else relevant to the testing or safe handling of the liquid in question.

The notes should also identify the source or standards organization used in establishing the testing method as appropriate for the liquid in question. For example, it could identify a source authority as the American branch of the International Society for Testing Materials.

The table should also indicate the organization’s applicable standard or testing method. Each standard identifies the testing method and the types of materials for which it is appropriate. For example, the suffix D92 indicates that the flash point and fire point temperatures were determined using the Standard Test Method for Flash and Fire Points by Cleveland Open Cup Tester method, which is deemed appropriate for all petroleum products with flash point temperatures above 175 and below 752 degrees Fahrenheit.

The flash point of a liquid is the minimum temperature at which its vapors combust in the presence of an external ignition source. The fire point is the minimum temperature at which the liquid can sustain combustion, and the auto-ignition temperature is that temperature at which the liquid can spontaneously combust without the application of an external ignition source.
