3、asurement of the inherentstability of middle distillate petroleum fuels under specifiedoxidizing conditions at 95 C.NOTE1Fuels used in establishing the precision measures for this testmethod were described as gas oil,diesel fuel,No.2 heating oil,and DFM,a Navy distillate fuel suitable for diesels,bo
4、ilers,and gas turbines.(Theterm DFM is no longer used when referring to fuel meeting MIL-F-16884requirements;rather it is called F76 as it conforms to NATO F76requirements.)While the test method may be used for fuels outside therange of these fuels,the precision measures may not apply.1.2 This test
5、method is not applicable to fuels containingresidual oil.This test method has not been validated for testingbiodiesel,such as meeting Specification D6751 or blends ofmiddle distillates and biodiesel,such as meeting SpecificationD7467,or both.Test Method D7462 has been determined to besuitable for te
