In industrial applications, electrical cables often get in contact with many types of oils. Basically, the different oils such as hydraulic oil or diesel oil can cause damage to the cables and lead to failure during continuous use.
To ensure failure-free production without long downtimes, applied cables should be oil-resistant and suitable for the specific application.
The oil resistance of cables and wires can be classified into two grades:
Oil resistance: TMPU according to EN 50363-10-2 and VDE 0207-363-10-2
Oil resistance: TM5 according to EN 50363-4 and VDE 0207-363-4
The test procedure and requirements can be seen in the following overview:
1. Test method
- acc. to IEC 60811-404
- corresponds to EN 60811-404
- corresponds to VDE 0473-811-404
