Section 6.2.10 of SAE J2394 specifies the fluid resistance test for cable insulation. Specimens are immersed in specified fluids (fuels, oils, coolants) for defined periods and then tested for retention of physical properties.
Fluid resistance is critical for automotive cables that may be exposed to engine fluids, transmission fluid, brake fluid, and other chemicals encountered in vehicle wiring environments.
This test evaluates the resistance of material to degradation when exposed to specified fluids as specified in BMS 1352. Specimens are immersed in the test fluid at the specified temperature for the required duration, then tested for changes in physical and/or electrical properties.
Fluid resistance testing is essential for products used in environments where exposure to fuels, hydraulic fluids, lubricants, or other chemicals may occur. The retention of properties after fluid exposure confirms the material’s suitability for the intended application.
