Oil Immersion Test

IEC 60811 Part 404 specifies the method for a mineral oil immersion test, which typically applies to cross-linked compounds used for sheathing materials. The purpose of the oil immersion test is to determine whether the material can be classified as oil resistant.

• The test methodology states that five test pieces shall be prepared in accordance with the procedures described in BS EN/IEC 60811-501, the test for cable tensile and elongation measurement.
• The test pieces are immersed in an oil bath which has been previously heated to the specified test temperature, and then the samples are maintained in the oil at temperature for the specified time.
• The mineral oil to be used shall be oil no. 2 (IRM 902) as described in ISO 1817
