How long must a timed pressure drop test be conducted according to RV standards?

The correct duration for conducting a timed pressure drop test, according to RV standards, is three minutes. This timeframe is established to ensure that the test is adequate for accurately measuring the pressure drop across various components in the system. A shorter duration might not sufficiently capture the dynamics of pressure changes, which can lead to inconclusive or misleading results. By adhering to a three-minute period, technicians are able to detect potential leaks or inefficiencies effectively, ensuring that the system is functioning correctly and safely.

Longer durations, while potentially providing more data, are not typically necessary for a standard pressure drop assessment. Therefore, the three-minute benchmark is considered the standard for achieving reliable and consistent results in evaluating the integrity of RV systems.
