(Test Method)Standard Test Method for Flash and Fire Points by Cleveland Open Cup
Standard Test Method for Flash and Fire Points by Cleveland Open Cup
SCOPE
1.1 This test method describes the determination of the flash and fire point of petroleum products by a manual Cleveland open cup apparatus or an automated Cleveland open cup apparatus.
Note 1—The precisions for fire point were not determined in the current interlaboratory program. Fire point is a parameter which is not commonly specified, although in some cases, knowledge of this flammability temperature may be desired.
1.2 This test method is applicable to all petroleum products with flash points above 79° C (175° F) and below 400° C (752° F) except fuel oils.
Note 2—This test method may occasionally be specified for the determination of the fire point of a fuel oil. For the determination of the flash points of fuel oils, use Test Method D 93. Test Method D 93 should also be used when it is desired to determine the possible presence of small, but significant concentrations of lower flash point substances which may escape detection by Test Method D 92. Test Method D 1310 can be employed if the flash point is known to be below 79° C (175° F).
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see 6.4, 7.1, 11.1.3, and 11.2.4.

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 combustion 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 of 49°C (120°F).
