The pipeline is evaluated as sealed during comparison of a smaller resultant pressure drop with a maximum allowable pressure drop. The pipeline is evaluated as untight during comparison of a larger resultant pressure drop with the maximum allowable pressure drop. An independent claim is also included for a brake test device for testing air tightness of a main air pipeline of a railway vehicle.",
