Which of the following is NOT part of the required information for the Air Brake Test Form?

The required information for the Air Brake Test Form is designed to ensure that all critical aspects of the air brake testing process are documented thoroughly for safety and compliance. Key elements include the location where the test was performed, the number of cars inspected, and the date and time the test was completed. These pieces of information help establish accountability and traceability of the air brake testing process critical for operational safety.

While having an emergency contact for the crew is important for overall safety protocols, it is not specifically required on the Air Brake Test Form itself, which focuses more on the testing parameters and conditions rather than personnel or emergency contact details. Thus, the absence of an emergency contact in the context of the Air Brake Test Form does not compromise the essential data required for evaluating the effectiveness and compliance of the air brake system.
