2、sion.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This test method covers the determination of the flashpoint of fuels including diesel/biodiesel blends,lube oils,solvents,and other
3、 liquids by a continuously closed cup testerutilizing a specimen size of 2 mL,cup size of 7 mL,with aheating rate of 2.5 C per minute.1.1.1 Apparatus requiring a specimen size of 1 mL,cup sizeof 4 mL,and a heating rate of 5.5 C per minute must be runaccording to Test Method D6450.1.2 This flash poin
4、t test method is a dynamic method anddepends on definite rates of temperature increase.It is one ofthe many flash point test methods available and every flashpoint test method,including this one,is an empirical method.NOTE1Flash point values are not a constant physical chemicalproperty of materials
5、tested.They are a function of the apparatus design,the condition of the apparatus used,and the operational procedure carriedout.Flash point can,therefore,only be defined in terms of a standard testmethod and no general valid correlation can be guaranteed between resultsobtained by different test met
6、hods or where different test apparatus isspecified.1.3 This test method utilizes a closed but unsealed cup withair injected into the test chamber.1.4 This test method is suitable for testing samples with aflash point from 35 C to 225 C.NOTE2Flash point determinations below 35 C and above 225 Cmay be
7、 performed;however,the precision has not been determined belowand above these temperatures.1.5 If the users specification requires a defined flash pointmethod other than this method,neither this method nor anyother test method should be substituted for the prescribed testmethod without obtaining com
