1、Designation: D 5964 07Standard Practice forRubber IRM 901, IRM 902, and IRM 903 Replacement Oils forASTM No. 1, ASTM No. 2, and ASTM No. 3 Oils1This standard is issued under the fixed designation D 5964; the number immediately following the designation indicates the year oforiginal adoption or, in t

2、he case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.INTRODUCTIONTest Method D 471 was revised in February 1995, establishing IRM 902 and IRM 903 asr

3、eplacements for ASTM No. 2 and No. 3 immersion oils, respectively. Unlike ASTM No. 2 and No.3 oils, the two IRM oils are severely hydrotreated, have a demonstrated negativeAmes test and do notrequire cancer warning labels under the OSHA Hazard Communication Standard published inNovember 1983.Althoug

4、h it was attempted to match the effect of theASTM oils on rubber propertiesin immersion testing as closely as possible, in general, neither of the IRM oils produces test resultsexactly identical to the ASTM oils it replaced.Test Method D 471 was again revised in October 2006, establishing IRM 901 as

5、 a replacement forASTM No. 1 immersion oil. The replacement was necessitated by the sudden unavailability ofASTMNo. 1 oil. Comprehensive research and development was conducted to establish a suitablereplacement. A Precision and Bias statement will be prepared in accordance with Practice D 4483 atthe

6、 conclusion of a forthcoming interlaboratory test program and included in Test Method D 471.Although an attempt was made to match the effect of the ASTM No. 1 oil on rubber properties inimmersion testing as closely as possible, preliminary findings indicate that IRM 901 oil produces testresults that

7、 are not identical to the ASTM oil it replaced. Please refer to Test Method D 471, Table 1,for a description of the specific characteristics of IRM 901 and ASTM No. 1 oils.The selections for replacement ASTM No. 2 and No. 3 oils were made on the basis of an objectivecomprehensive test program as des

8、cribed in this practice and decisions on the data generated in thisprogram were made in open meetings of Subcommittee D11.15. The SAE Committee on AutomotiveRubber Specifications (CARS) made a recommendation on the replacement oils that was identical tothe decisions made by D11.15.This practice addr

9、esses the need for establishing a correlation between test results obtained withIRM versusASTM oils, based on results of the described test program.Although the test program wasquite comprehensive, it cannot begin to address the numerous variations in compound recipes used inthe rubber industry. Cor

10、relations established by this practice may therefore not always providesatisfactory results. In this case it is suggested that other approaches be used, such as a directcomparison of each specific rubber compound in the respective ASTM and IRM oils. All newspecifications, including oil immersion tes

11、ting, shall be established using IRM 901, IRM 902, andIRM 903 in place of ASTM No. 1, ASTM No. 2, and ASTM No. 3 oils, respectively.1. Scope1.1 This practice covers three immersion oils to be used asreplacements forASTM No. 1, No. 2, and No. 3 immersion oilsas called for in Test Method D 471. The im

12、mersion oils will bedesignated as IRM 901 as a replacement for ASTM No. 1 oil,IRM 902 as a replacement for ASTM No. 2 oil, and IRM 903as a replacement for ASTM No. 3 oil. The new reference oilshave been developed under a new Committee D11 policy onreference materials (see Practice D 4678 for backgro

13、und on thenew policy and procedures).1.2 The oils, IRM 901, IRM 902, and IRM 903, are similarbut not fully equivalent to ASTM No.1, ASTM No. 2, andASTM No. 3 oil, respectively. Refer to Table 1 for a descrip-tion of the typical properties and specifications for these oils.1This practice is under the

14、 jurisdiction ofASTM Committee D11 on Rubber andis the direct responsibility of Subcommittee D11.15 on Degradation Tests.Current edition approved Nov. 1, 2007. Published December 2007.

16、ary background and detailson the changeover from the previous oils to the new oils. SeeAnnex A1 for additional information on the commercial oilsselected to replace ASTM No. 2 and No. 3 oil and the testprogram conducted for this selection process. The changeoverfrom ASTM to IRM oils is proposed in t

17、wo steps:1.3.1 Step 1A transition phase that makes use of theEquivalent Volume Swell (EVS) for each of the two replace-ment oils. EVS(902) is the ASTM No. 2 percent volume swellvalue calculated from the measured percent volume swell valueusing IRM 902 as the immersion liquid. A similar calculationca

18、n be used to calculate the analogous EVS(903) andEVS(903) values. The EVS value is obtained as a correction ofthe measured IRM 901, 902, or 903 percent volume swellvalue. The EVS values may be used to determine if volumeswell specifications are met when the specifications are ex-pressed in terms of

19、ASTM No. 1, No. 2, or No. 3 limits, and1.3.2 Step 2Alonger term policy change or conversion ofspecifications from ASTM No. 1, No. 2, and No. 3 values toIRM 901, 902, and 903 values.1.4 The EVS values are calculated on the basis of “correc-tion equations” derived from one of two sources.1.4.1 Correct

20、ion equations derived from the results of thecomprehensive evaluation program conducted to select each ofthe two replacement oils from a group of three candidate oilsfor ASTM No. 2 and No. 3 oils. This program is described inAnnex A1.1.4.2 Correction equations derived from in-house custom-ized or sp

33、2 andASTMNo. 3 immersion oils, designated IRM 902 and IRM 903,respectively, were selected on the basis of the closest match toASTM No. 2 and ASTM No. 3 oils in the comprehensiveevaluation program as outlined in Annex A1.34.2 The oil selected to replace ASTM No. 1 immersion oilwas selected on the bas

Converting ASTM Oil to IRM Oil Volume SwellValues5.1 Basis of ConversionOne of the important issues fo

35、rany user of the IRM oils, especially producer-consumer opera-tions, is the relationship and conversion of the customaryASTM oil volume swell values for proprietary and commercialcompounds to volume swell values for the new IRM oils. Asoutlined in the scope, this can be done on the basis of twoappro

36、aches.5.1.1 Calculating EVS values for IRM 901, IRM 902, orIRM 903 for any commercial compound based on (1) selectingfrom Table A1.1 and Appendix X1, the compound nearest tothe commercial compound in composition, and (2) using thepercent difference (PC d) value for this compound in theconversion or

37、correction calculation. This EVS value is anapproximate value.5.1.2 Organizing a special in-house testing program toobtain volume swell values under the appropriate conditions(time and temperature of immersion) for the selected ASTMand IRM oils for the proprietary or commercial compounds ofinterest.

38、 Once data for both oils are obtained, the relationshipbetween the two oils is established.5.1.3 If needed for future applications, calculations can bemade to correct or convert theASTM values to the IRM valuesor vice-versa for other compounds where the correction can belegitimately applied. This ap

39、proach gives corrections that arespecific to the compounds of interest; it is direct and substan-tially more accurate than the approximate approach and is therecommended conversion procedure for exact and criticalspecification applications if corrections of this sort are re-quired.5.2 Conversion Usi

40、ng the EVS ProcedureTwo proceduresare given: (1) for converting IRM values to equivalent ASTMvalues, and (2) for converting ASTM values to IRM values.The second operation may be of value in converting existingASTM value specifications to IRM value specifications as theold ASTM oil specification valu

41、es are phased out.5.2.1 Eq 1 gives the EVS(902) value, the equivalent ASTMNo. 2 oil percent volume swell value for IRM 902 oil, based onmeasured volume swell data in IRM 902 and data inTableA1.1of Annex A1.EVS902!5MVS902!S1 1PC d1100D(1)where:EVS (902) = EVS (approximate) for IRM 902 oil,MVS (902) =
