Designation:D637105(Reapproved 2010)Standard Test Method forCold Filter Plugging Point of Diesel and Heating Fuels1This standard is issued under the fixed designation D6371;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.Scope1.1 This test method covers the determination of the coldfilter plugging point(CFPP)temperature of diesel and domes-tic heating fuels using either manual or automated apparatus.NOTE1This test method is technically equivalent to test methodsIP 309 and EN 116.1.2 The manual apparatus and automated apparatus are bothsuitable for referee purposes.1.3 This test method is applicable to distillate fuels,includ-ing those containing a flow-improving or other additive,intended for use in diesel engines and domestic heatinginstallations.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 WARNINGMercury has been designated by manyregulatory agencies as a hazardous material that can causecentral nervous system,kidney and liver damage.Mercury,orits vapor,may be hazardous to health and corrosive tomaterials.Caution should be taken when handling mercury andmercury containing products.See the applicable product Ma-terial Safety Data Sheet(MSDS)for details and EPAswebsitehttp:/www.epa.gov/mercury/faq.htmfor addi-tional information.Users should be aware that selling mercuryand/or mercury containing products into your state or countrymay be prohibited by law.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.For specificwarning statements,see Section 7.2.Referenced Documents2.1 ASTM Standards:2D2500 Test Method for Cloud Point of Petroleum ProductsD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD4177 Practice for Automatic Sampling of Petroleum andPetroleum ProductsD5771 Test Method for Cloud Point of Petroleum Products(Optical Detection Stepped Cooling Method)D5772 Test Method for Cloud Point of Petroleum Products(Linear Cooling Rate Method)D5773 Test Method for Cloud Point of Petroleum Products(Constant Cooling Rate Method)E1 Specification for ASTM Liquid-in-Glass Thermometers2.2 IP Standards:3IP 309 Diesel and domestic heating fuels-Determination ofcold filter plugging pointSpecifications for IP Standard Thermometers2.3 ISO Standards:4IP 3310 Test sieves-Technical requirements and testing-Part 1:Metal cloth2.4 European Standards:5EN 116 Diesel and domestic heating fuels-Determinationof cold filter plugging point1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.07 on Flow Properties.Current edition approved Aug.1,2010.Published November 2010.Originallyapproved in 1999.Last previous edition approved in 2005 as D637105.DOI:10.1520/D6371-05R10.2For 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.3Available from Energy Institute,61 New Cavendish St.,London,WIG 7AR,U.K.,http:/www.energyinst.org.uk.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.5Available from European Committee for Standardization(CEN),36 rue deStassart,B-1050,Brussels,Belgium,http:/www.cenorm.be.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 certified reference material,na stable petroleumproduct with a method-specific nominal CFPP value estab-lished by a method-specific interlaboratory study followingRR:D02-10076guidelines or ISO Guides 34 and 35.43.1.2 cold filter plugging point,nhighest temperature,expressed in multiples of 1C,at which a given volume of fuelfails to pass through a standardized filtration device in aspecified time when cooled under the conditions prescribed inthis test method.4.Summary of Test Method4.1 A specimen of the sample is cooled under specifiedconditions and,at intervals of 1C,is drawn into a pipet undera controlled vacuum through a standardized wire mesh filter.The procedure is repeated,as the specimen continues to cool,for each 1C below the first test temperature.Testing iscontinued until the amount of wax crystals that have separatedout of solution is sufficient to stop or slow down the flow sothat the time taken to fill the pipet exceeds 60 s or the f
