Designation:D428913(Reapproved 2014)1Standard Test Method forElastomer Compatibility of Lubricating Greases and Fluids1This standard is issued under the fixed designation D4289;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.1NOTEAMS 3217/3B references were updated editorially in October 2014.1.Scope1.1 This test method evaluates the compatibility of lubricat-ing greases and fluids with coupons cut from standard elasto-mer sheets(Practice D3182)or,optionally,from SAE Speci-fication AMS 3217/2C(NBR-L)and AMS 3217/3B(CR)sheets.Compatibility is evaluated by determining the changesin volume and Durometer A hardness that occur when elasto-mer coupons are totally immersed in a lubricant sample for 70h at either 100 or 150C or as required by the lubricantspecification.1.1.1 Some lubricant specifications may require differenttest conditions,such as longer durations or lower or highertemperatures.In such instances,the repeatability and reproduc-ibility values stated in Section 12 do not apply,and the user andsupplier should agree on acceptable limits of precision.NOTE1The scope of this test method now includes the evaluation ofthe elastomer compatibility of both lubricating fluids and greases.Testingof fluids was not included in Test Method D428995 and earlier versions.1.2 This test method can also be used as a guide to evaluatethe compatibility of greases with rubber products not instandard sheet form(Practice D3183).1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3.1 ExceptionWhen listed,Durometer A units shall beregarded as the standard.1.4 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 specific warningstatements,see 8.4 8.6.2.Referenced Documents2.1 ASTM Standards:2D217 Test Methods for Cone Penetration of LubricatingGreaseD297 Test Methods for Rubber ProductsChemical Analy-sisD412 Test Methods for Vulcanized Rubber and Thermoplas-tic ElastomersTensionD471 Test Method for Rubber PropertyEffect of LiquidsD1193 Specification for Reagent WaterD2240 Test Method for Rubber PropertyDurometer Hard-nessD3182 Practice for RubberMaterials,Equipment,and Pro-cedures for Mixing Standard Compounds and PreparingStandard Vulcanized SheetsD3183 Practice for RubberPreparation of Pieces for TestPurposes from ProductsD4175 Terminology Relating to Petroleum,PetroleumProducts,and LubricantsD4950 Classification and Specification for Automotive Ser-vice Greases2.2 Federal Standards:3Federal Test Method Standard 791C,Method 3603.5,Swell-ing of Synthetic Rubbers2.3 U.S.Air Force Specifications:4USAF-539 Specification Bulletin for Standard ElastomerStocks1This test method is under the jurisdiction of ASTM Committee D02 onPetroleum Products,Liquid Fuels,and Lubricants and is the direct responsibility ofSubcommittee D02.G0.01 on Chemical and General Laboratory Tests.Current edition approved Oct.1,2014.Published November 2014.Originallyapproved in 1989.Last previous edition approved in 2013 as D4289 13.DOI:10.1520/D4289-13R14E01.2For 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 Standardization Documents Order Desk,Bldg.4,Section D,700 Robbins Ave.,Philadelphia,PA 19111-5094,Attn:NPODS.4USAF-539 is obsolete,but reproductions have been filed atASTM InternationalHeadquarters and may be obtained by requesting Research Report RR:D02-1165.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.4 SAE Standards:5AMS 3217A Standard Elastomer StocksTest SlabsAMS 3217/2C Test Slabs,Acrylonitrile Butadiene(NBR-L)Low Acrylonitrile,6575AMS 3217/3B Test Slabs,Chloroprene(CR)6575NOTE2USAF-539 was specified in Test Method D428994 andearlier versions.This specification is obsolete and has been replaced bySAE Standard AMS 3217A.USAF-539 NBR-L was replaced by SAEAMS 3217/2C(NBR-L),which is virtually identical.USAF-539 CR hasbeen replaced by the similar,but not identical,SAE AMS 3217/3B(CR).Elastomer sheets prepared to this latter specification are not known orexpected to provide test results identical with those of the USAF-539counterpart.NOTE3With respect to elastomer AMS 3217/2A,the elastomerspecification was superseded by AMS 3217/2B.Per SAE,the elastomersare identical,however,
