Designation:D621711Designation:415/98Standard Test Method forParticulate Contamination in Middle Distillate Fuels byLaboratory Filtration1This standard is issued under the fixed designation D6217;the number immediately following the designation indicates the year oforiginal adoption or,in the case 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 distillate 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 38C.NOTE1Middle distillate fuels with flash points less than 38C 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 contamination in Specification D1655 aviation turbine fuelsand other similar aviation fuels.See Guide D4865 for a more detaileddiscussion of static electricity formation and discharge.1.3 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 D7321 has been determined to besuitable for testing B100 and all blends of middle distillatesand biodiesel.NOTE2No.1 and No.2 grades in Specifications D396 or D975currently allow up to 5%biodiesel meeting Specification D6751.Samplescontaining biodiesel can result in partial dissolution or compromise of themembrane filters and give erroneous results.1.4 The precision of this test method is applicable toparticulate contaminant levels between 0 to 25 g/m3providedthat 1 L samples are used and the 1 L is filtered completely.Higher levels of particulate contaminant can be measured,butare subject to uncertain precision.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D56 Test Method for Flash Point by Tag Closed Cup TesterD93 Test Methods for Flash Point by Pensky-MartensClosed Cup TesterD396 Specification for Fuel OilsD975 Specification for Diesel Fuel OilsD1193 Specification for Reagent WaterD1655 Specification for Aviation Turbine FuelsD2069 Specification for Marine Fuels(Withdrawn 2003)3D2276 Test Method for Particulate Contaminant in AviationFuel by Line SamplingD2880 Specification for Gas Turbine Fuel OilsD3699 Specification for KerosineD3828 Test Methods for Flash Point by Small Scale ClosedCup TesterD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4865 Guide for Generation and Dissipation of Static Elec-tricity in Petroleum Fuel SystemsD5452 Test Method for Particulate Contamination in Avia-tion Fuels by Laboratory FiltrationD6751 Specification for Biodiesel Fuel Blend Stock(B100)for Middle Distillate FuelsD7321 Test Method for Test Method for Particulate Con-tamination of Biodiesel B100 Blend Stock BiodieselEsters and Biodiesel Blends by Laboratory FiltrationD7467 Specification for Diesel Fuel Oil,Biodiesel Blend(B6 to B20)1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.14 on Stability and Cleanliness of Liquid Fuels.Current edition approved May 1,2011.Published June 2011.Originallyapproved in 1998.Last previous edition approved in 2010 as D621710.DOI:10.1520/D6217-11.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.Terminology3.1 Definitions:3.1.1 bond,vto connect two parts of a system electricallyby means of a conductive wire to eliminate voltage differences.3.1.2 ground,vto connect electrically with earth.3.1.3 membrane filter,na porous article of closely con-trolled pore size through which a liquid is passed to separatematter in suspension.3.2 Definitions of Terms Specific to This Standard:3.2.1 co
