How is a low-pressure container defined?

A low-pressure container is defined as one that can withstand pressures between 0.5 and 15 psig. This range specifically characterizes these containers, indicating they are built to safely hold contents at relatively low pressures compared to high-pressure containers, which are defined as being designed for pressures above 15 psig. Therefore, the definition encompasses both the structural capabilities of the container and the operational context in which it is used.

In this context, the answer emphasizes the distinction of low-pressure containers, which are not to be confused with those designed for higher pressures or those that store liquid gases exclusively. This helps ensure proper safety and usage standards in environments where these types of gases are handled.
