According to Brake Pipe Leakage Method procedures, what is the allowable leakage for the test to be considered complete?

The allowable leakage for the Brake Pipe Leakage Method to be considered complete is 5 psi. This standard ensures that the braking system maintains sufficient pressure for effective operation. Leakage beyond this threshold could indicate potential issues within the system, such as faulty components or connections that may compromise overall safety.

The 5 psi threshold reflects a balance between ensuring the system is performing effectively while allowing for a minimal degree of acceptable variance that might occur in real-world conditions. This standard is critical for maintaining safety and operational efficiency in rail operations.
