What must be tested in bonding connections to ensure proper installation?

In bonding connections, testing the resistance value is essential to ensure proper installation. Bonding is the process of connecting conductive parts to establish an electrical connection that helps in reducing electromagnetic interference and ensuring safety by preventing the buildup of static charge.

A low resistance value in bonding connections signifies that there is a good electrical connection, allowing for efficient current flow. If the resistance is too high, it may indicate a poor bond, which can lead to degraded performance or potential hazards such as arcing or electrical fires.

This testing ensures that the bonding connections will effectively carry fault currents in the event of a short circuit and help maintain the overall integrity and safety of the aircraft’s electrical system. Thus, validating that the resistance is within acceptable limits is crucial for reliable aircraft operation.
