What specific information should be documented on a timed pressure drop test when conducted at the range?

When performing a timed pressure drop test, the most critical pieces of information to document are the manometer measurement and the duration of the test. The manometer reading indicates the pressure level being assessed and allows for tracking any changes that occur over time. The duration of the test is important as it provides a timeframe in which the pressure drop is observed, which is crucial for evaluating the integrity of the system being tested.

This data is vital for determining whether the setup meets safety and operational standards, and it can help identify leaks or inefficiencies in the system. Recording both the manometer measurement and the test duration allows for thorough analysis and ensures that any potential issues can be accurately assessed and addressed.
