An American National Standard Designation:D 92-02b Amencan Associalion Slale Highway and Transportation Officials Standard ul AASHTO No.:T48 INTERNATIONAL DIN51376 IP Designation:36/84(89) Standard Test Method for Flash and Fire Points by Cleveland Open Cup Testert This standard is issued under the fixed designation D 92: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 standard has been approved for use by agencies of the 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 79C(175F)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 D 4206 which is a sustained burning test open cup type at a specific temperature of49C(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 corre...
