3、nd IRM 903 asreplacements 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 inNovembe

4、r 1983.Although 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 D471 was again revised in October 2006, establishi

5、ng IRM 901 as 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

6、 D4483 atthe conclusion of a forthcoming interlaboratory test program and included in Test Method D471.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 testr

7、esults that are not identical to the ASTM oil it replaced. Please refer to Test Method D471, 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 prog

8、ram as described 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 pra

9、ctice addresses 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 ind

10、ustry. Correlations 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 imm

11、ersion testing, 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 D47

12、1. The immersion 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 D4678 for

13、 background on thenew policy and procedures).1This practice is under the jurisdiction ofASTM Committee D11 on Rubber andis the direct responsibility of Subcommittee D11.15 on Degradation Tests.Current edition approved May 1, 2014.

15、ctively. Refer to Table 1 for a descrip-tion of the typical properties and specifications for these oils.1.3 This practice gives the necessary background and detailson the changeover from the previous oils to the new oils. SeeAnnex A1 for additional information on the commercial oilsselected to repl

16、ace ASTM No. 2 and No. 3 oil and the testprogram conducted for this selection process. The changeoverfrom ASTM to IRM oils is proposed in two 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 perc

17、ent volume swellvalue calculated from the measured percent volume swell valueusing IRM 902 as the immersion liquid. A similar calculationcan 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 sw

18、ellvalue. The EVS values may be used to determine if volumeswell specifications are met when the specifications are ex-pressed in terms of ASTM No. 1, No. 2, or No. 3 limits, and1.3.2 Step 2A longer term policy change or conversion ofspecifications from ASTM No. 1, No. 2, and No. 3 values toIRM 901,

19、 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 Correction equations derived from the results of thecomprehensive evaluation program conducted to select each ofthe two replacement oils from a group of three candidat

20、e 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 specific testing programs to make direct comparisons ofthe volume swell (and other important properties) of the IRMand ASTM oils. These programs should be conduct

Significance and Use3.1 The reference immersion oils described in this practiceare required for the development of oil-resistant rubber com-pounds for use in environments where contact with petroleum-based solvent

31、s and oils is encountered. Tests for tensilestrength, percent elongation at break, hardness, and percentvolume swell are performed after a specified immersion timeperiod (at a specified temperature) in the evaluation of oil-resistant rubbers. The results of such testing by rubber productmanufacturer

32、s and their customers are used to develop oil-resistant rubbers or compounds, or both.3.2 Testing withASTM Oils No. 1, No. 2, and No. 3 is usedto verify compliance with purchase specifications which refer-ence the oil-resistant classes of rubbers and elastomers listed inTable 6 of Classification D20

33、00. These oils are also used incomparative performance evaluation testing of O-rings andO-ring compounds as cited in Test Methods D1414. The use ofthese reference oils is required for the development andselection of oil-resistant rubber compounds having acceptableor optimum performance characteristi

Specifying IRM 901, 902, and 903 ReferenceImmersion Oils4.1 The two oils selected to replaceASTM No. 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 comprehensiveevaluat

35、ion program as outlined in Annex A1.34.2 The oil selected to replace ASTM No. 1 immersion oilwas selected on the basis of the closest match to ASTM No. 1oil in an evaluation program and designated as IRM 901.4.3 The (petroleum) specifications and typical properties ofIRM 901, 902, and 903 are given

36、in Table 1.5. Converting ASTM Oil to IRM Oil Volume SwellValues5.1 Basis of ConversionOne of the important issues forany user of the IRM oils, especially producer-consumeroperations, is the relationship and conversion of the customaryASTM oil volume swell values for proprietary and commercialcompoun

37、ds to volume swell values for the new IRM oils. Asoutlined in the scope, this can be done on the basis of twoapproaches.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 commerci

38、al compound in composition, and (2) using thepercent difference (PC d) value for this compound in theconversion or 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

39、temperature of immersion) for the selected ASTMand IRM oils for the proprietary or commercial compounds ofinterest. 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

40、 values to the IRM valuesor vice-versa for other compounds where the correction can belegitimately applied. This approach 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 proc

41、edure for exact and criticalspecification applications if corrections of this sort are re-quired.5.2 Conversion Using 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 valu

42、e in converting existingASTM value specifications to IRM value specifications as theold ASTM oil specification values 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 in

43、 TableA1.1 of Annex A1.EVS902! 5MVS902!S11PCd1100D(1)where:EVS (902) = EVS (approximate) for IRM 902 oil,MVS (902) = measured percent volume swell in IRM 902oil, andPC d1= difference between volume swells in IRM902 oil and ASTM No. 2 oil expressed as arelative percentage (from Table A1.1, se-lected

44、in accordance with 5.1.1).5.2.2 Eq 2 may be used for converting IRM values toASTMvalues for compounds of commercial interest on the same basisas described above.EVSNo. 2! 5MVSNo. 2!S11PC d2100D(2)where:EVS (No. 2) = EVS (approximate) for ASTM No. 2 oil,MVS (No. 2) = measured percent volume swell in

Testing Precision6.1 Although a precision statement is not a mandatorysection in a practice, the precisi

48、on of volume swell testing is animportant issue for the conversion from the originalASTM oilsto the IRM oils.
