How should appliances designed for lower operating pressures than test pressures be handled?

Appliances designed for lower operating pressures than the specified test pressures must be capped or disconnected to ensure safety and integrity. This practice is vital because when these appliances are exposed to higher test pressures than they are rated for, there is a significant risk of damage or failure. Capping or disconnecting them prevents potential leaks, ruptures, or hazardous situations that could arise from the increased stress on the appliance's structure. By taking these precautions, safety is prioritized, and the potential for accidents is minimized, which aligns with best practices in handling such equipment.
