1、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
2、 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 edit
3、orially 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 determini
4、ng 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
5、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 bot
6、h 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
7、 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 us
8、er 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
