Designation:D92-16a American Association State Highway and Transportation Officials Standard T AASHTO No.:T48 INTERNATIONAL DIN51376 Standard Test Method for Flash and Fire Points by Cleveland Open Cup Tester This standard is issued under the fixed designation D92;the number immediately following the designation indicates the year of original adoption or in the case of revision the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon (e)indicates an editorial change since the last revision or reapproval. This standand has been approved for use by agencies of the U.S.Department of Defense. INTRODUCTION This flash point and fire point test method is a dynamic method and depends on definite rates of temperature increases to control the precision of the test method.Its primary use is for viscous materials having flash point of 79 C(175 F)and above.It is also used to determine fire point which is a temperature above the flash point at which the test specimen will support bustion for a minimum of 5 s.Do not confuse this test method with Test Method D4206 which is a sustained burning test open cup type at a specific temperature of49℃(120F). Flash point values are a function of the apparatus design the condition of the apparatus used and the operational procedure carried out.Flash point can therefore only be defined in terms of a standard test method and no general valid correlation can be guaranteed between results obtained by ...
