What is the minimum duration for an NH3 test?

The minimum duration for an NH3 (ammonia) test being set at 24 hours is important because it allows for sufficient time to accurately gather data on the system's performance under various conditions. This extended duration is necessary to ensure that any possible leaks or anomalies in the piping system are detected, as ammonia can have significant safety and environmental implications. Testing for a full 24 hours helps to capture variations in pressure and temperature, which might not be evident in a shorter test window. A full day of monitoring can reveal trends and ensure that the system is stable and operating within the required safety parameters, making it a critical component of piped ammonia operations.
