| Test Item | Requirement |
|---|---|
| Open/Short Test | 100% testing |
| High Voltage | AC 100V for 0.1 second |
| Insulation Resistance | Minimum 10 megaohms at DC 300V |
| Contact Resistance | Maximum 3 ohms |
1. Open/Short Test (100% testing): This test ensures that there are no open circuits or short circuits in the electrical
system by conducting thorough testing on all connections and components.
2. High Voltage (AC 100V for 0.1 second): This test applies a high voltage of AC 100V for a duration of 0.1 second
to check the insulation and withstand capability of the electrical components under high voltage conditions.
3. Insulation Resistance (Minimum 10 megaohms at DC 300V): This test measures the insulation resistance of the electrical
system when subjected to a direct current (DC) voltage of 300V, with a minimum requirement of 10 megaohms to ensure
adequate insulation between conductors.
4. Contact Resistance (Maximum 3 ohms): This test evaluates the resistance between contacts in electrical connectors, ensuring that it does not exceed a maximum value of 3 ohms to maintain efficient electrical conductivity and minimize voltage drops.
