Designation:D47116a(Reapproved 2021)Standard Test Method forRubber PropertyEffect of Liquids1This standard is issued under the fixed designation D471;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This test method covers the required procedures toevaluate the comparative ability of rubber and rubber-likecompositions to withstand the effect of liquids.It is designedfor testing:(1)specimens of vulcanized rubber cut fromstandard sheets(see Practice D3182),(2)specimens cut fromfabric coated with vulcanized rubber(see Test Methods D751),or(3)finished articles of commerce(see Practice D3183).Thistest method is not applicable to the testing of cellular rubbers,porous compositions,and compressed sheet packing,except asdescribed in 12.2.2.1.2 Periodically,it is necessary to produce a new lot of anIRM oil to replace the dwindling supply of the current product.The Chairman of the subcommittee shall have the authority toapprove the production of a replacement lot.Once produced,the technical data of the new lot shall be presented,in acomparative fashion,to that of the existing lot and ballotedupon by the membership of the D11.15 subcommittee and,either subsequently or concurrently,balloted upon by themembership of the D11 main committee for approval to releasethe new lot for distribution.1.3 In the event that an IRM oil becomes unavailable fordistribution due to depletion,the Chairman of the subcommit-tee shall have the authority to approve production of a new lotand,after a meeting of the task group,regularly scheduled,ornot,to release a quantity of the product for distributionsufficient enough only to address a backlog.Once the backlogis addressed,the process described in 1.2 shall be followed.1.4 ASTM Oils No.2 and No.3,formerly used in this testmethod as standard test liquids,are no longer commerciallyavailable and in 1993 were replaced with IRM 902 and IRM903,respectively(see Appendix X1 for details).1.5 ASTM No.1 Oil,previously used in this test method asa standard test liquid,is no longer commercially available andin 2005 was replaced with IRM 901;refer to Table 1 andAppendix X3 for details.1.6 ASTM No.5 Oil was accepted into Specification D5900as an industry reference material in 2010 and designated asIRM 905.The composition,and properties of this immersionoil were not changed and the data in Table 1 remains current.Refer to Appendix X4 for other details.1.7 The specifications and properties listed in Table 1 forIRM 901,IRM 902,IRM 903,and IRM 905 are alsomaintained in Specification D5900.1.7.1 The subcommittee responsible for maintaining TestMethod D471,presently D11.15,shall review the data inSpecification D5900 to ensure that it is identical to that whichappears in Test Method D471.This shall be accomplished atthe time of the 5 year review or more frequently whennecessary.1.8 Historical,technical,and background information re-garding the conversion from ASTM No.1,ASTM No.2,andASTM No.3 Oils to IRM 901,IRM 902,and IRM 903immersion oils is maintained in Practice D5964.1.8.1 The subcommittee responsible for maintaining TestMethod D471,presently D11.15,shall review the data inPractice D5964 to ensure that it is identical to that whichappears in Test Method D471.This shall be accomplished atthe time of the 5 year review or more frequently whennecessary.1.9 This test method includes the following:Change in Mass(after immersion)Section 11Change in Volume(after immersion)Section 12Dimensional-Change Method for Water-Insoluble Liq-uids and Mixed LiquidsSection 13Change in Mass with Liquid on One Surface OnlySection 14Determining Mass of Soluble Matter Extracted by theLiquidSection 15Change in Tensile Strength,Elongation and Hardness(after immersion)Section 16Change in Breaking Resistance,Burst Strength,TearStrength and Adhesion for Coated FabricsSection 17Calculation(of test results)Section 181.10 The values stated in SI units are to be regarded as thestandard.The values in parentheses are for information only.1.11 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is the1This test method is under the jurisdiction of ASTM Committee D11 on Rubberand Rubber-like Materials and is the direct responsibility of Subcommittee D11.15on Degradation Tests.Current edition approved May 1,2021.Published June 2021.Originallyapproved in 1937.Last previous edition approved in 2016 as D471 16a.DOI:10.1520/D0471-16AR21.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization establishe
