Critical Shift from ISO 6722
ISO 19642 introduces specific test regimens for AC (up to 1000V) and DC (up to 1500V) applications, reflecting modern EV powertrains.
Common Mistakes
Engineers often apply legacy 60V DC fluid compatibility tests to 1000V AC systems, resulting in catastrophic dielectric breakdown during validation.
| Class | Temp Limit |
|---|---|
| Class C | 125°C |
| Class D | 150°C (Typical for engine bays) |
FAQ
Q: Does ISO 19642 mandate orange sheathing for HV?
A: Yes, for components carrying voltages class B (e.g. >60V DC), visual identification is strictly required.
