2、 of revision,the year of last revision.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 mass ofparticulate contamination in a middle dis
3、tillate fuel by filtra-tion.This test method is suitable for all No.1 and No.2 gradesin Specifications D396,D975,D2880 and D3699 and forgrades DMA and DMB in Specification D2069.1.2 This test method is not suitable for fuels whose flashpoint as determined by Test Methods D56,D93 or D3828 isless than
4、 38 C.NOTE1Middle distillate fuels with flash points less than 38 C havebeen ignited by discharges of static electricity when the fuels have beenfiltered through inadequately bonded or grounded membrane filter sys-tems.See Test Methods D2276 and D5452 for means of determiningparticulate contaminatio
