What is the applied leakage test limit for a single vehicle?

The applied leakage test limit for a single vehicle is -3 psi. This standard is established to ensure the integrity of the vehicle's air brake system and to promote safety during operation. When conducting an applied leakage test, a vehicle is expected to maintain a pressure drop within acceptable limits. A limit of -3 psi indicates that the air brake system should not lose more than 3 psi during the test, showcasing its effectiveness and reliability.

Meeting this standard during testing helps to ensure that any potential leaks in the system are identified and addressed before the vehicle is put into service. Such preventive measures are crucial for the safety of both the operator and other road users, as efficient braking systems are vital for controlling the vehicle in emergency situations.
