ASTM and IRM Reference Oils
B. P. Chemicals is the Indian Distributor of IRM Testing Oils. We offer a range of test fluids for rubber and plastics chemical resistance studies. The range includes oils originating from ASTM and specified by international and national standards.
​
The compatibility of rubbers against reference oils - IRM 901 (Formerly ASTM No. 1 oil) IRM 902 & IRM 903 is a common test called for in material specifications.
The tests are often used to indicate compatibility against lubricating oils and greases, but are also a valuable quality tool to ensure consistency in rubber formulation.

Significance and Use
The reference immersion oils described are required for the development of oil-resistant rubber compounds for use in environments where contact with petroleum-based solvents and oils is encountered. Tests for tensile strength, percent elongation at break, hardness, and percent volume swell are performed after a specified immersion time period (at a specified temperature) in the evaluation of oil-resistant rubbers. The results of such testing by rubber product manufacturers and their customers are used to develop oil-resistant rubbers or compounds, or both.
​
Testing with ASTM Oils No. 1, No. 2, and No. 3 is used to verify compliance with purchase specifications which reference the oil-resistant classes of rubbers and elastomers listed in Table 6 of Classification D2000. These oils are also used in comparative performance evaluation testing of O-rings and O-ring compounds as cited in Test Methods D1414. The use of these reference oils is required for the development and selection of oil-resistant rubber compounds having acceptable or optimum performance characteristics, or both.
