Standard Practice for Rubber IRM 901, IRM 902, and IRM 903 Replacement Oils for No. 1, No. 2, No. 3 Oils, and IRM 905 formerly No. 5 Oil
N D5964
Annotation
This practice covers three immersion oils to be used as replacements forASTM No. 1, No. 2, and No. 3 immersion oils as called for in Test Method D471. The immersion oils will be designated as IRM 901 as a replacement for ASTM No. 1 oil, IRM 902 as a replacement for ASTM No. 2 oil, and IRM 903 as a replacement for ASTM No. 3 oil. The new reference oils have been developed under a new Committee D11 policy on reference materials (see Practice D4678 for background on the new policy and procedures).
The oils, IRM 901, IRM 902, and IRM 903, are similar but not fully equivalent to ASTM No.1, ASTM No. 2, and ASTM No. 3 oil, respectively. Refer to Table 1 for a description of the typical properties and specifications for these oils.
ASTM No. 5 Oil was accepted into Specification D5900 as an industry reference material in 2010 and designated as IRM 905. The composition, and properties of this immersion oil were not changed and the data in Table 1 remains current. It was listed among the IRM immersion oils in Test Method D471 in 2010.
This practice gives the necessary background and details on the changeover from the previous oils to the new oils. See Annex A1 for additional information on the commercial oils selected to replace ASTM No. 2 and No. 3 oil and the test program conducted for this selection process. The changeover from ASTM to IRM oils is proposed in two steps:
Step 1—A transition phase that makes use of the Equivalent Volume Swell (EVS) for each of the two replacement oils. EVS(902) is the ASTM No. 2 percent volume swell value calculated from the measured percent volume swell value using IRM 902 as the immersion liquid. A similar calculation can be used to calculate the analogous EVS(903) and EVS(903) values. The EVS value is obtained as a correction of the measured IRM 901, 902, or 903 percent volume swell value. The EVS values may be used to determine if volume swell specifications are met when the specifications are expressed in terms of ASTM No. 1, No. 2, or No. 3 limits, and
