1, pressure system The pressure system shall be able to produce a specified test pressure without vibration or pulse. For this purpose, a static water reservoir or pump may be used. The hydrostatic pressure test uses water, and the system can provide the required pressure without flowing. Pressure test to use compressed air, the system can provide the required pressure under the condition of no flow.2, the end of the connecting faucet should be fixed with a suitable table, and connected with the pressure system. The water inlet software pipe or special fixture can be connected. Note: The pressure device should be connected to the water inlet of the faucet. The test of each faucet of the combined faucet should ensure the integrity of each faucet. And take appropriate measures to protect the tester. For air pressure tests, measures are required to sink the component into the pool. For the extraction type faucet, the outlet should be able to free water, for the separation type faucet and hose faucet, the outlet of the faucet should be connected with a water flow control valve, to ensure free water or resist the pressure system to stop the flow, water pressure test, free water should be air and easy to see. For air pressure tests, the free flow requires bubbles from the pool.3. Manometer The manometer must be calibrated, be in service, and display the required test pressure with an error of not more than 2%.1 Note: Digital or simulation manometers with the same or greater accuracy may be used.
