installation, but prior to connection to the
regulator and appliance(s).
A-1.10.2 The cylinder valve shall be checked for leakage at its connection to the cylinder by application of a leak detection fluid prior to connection to the system.
A-1.10.3 After the above tests, the complete system shall be connected and shall be subjected to the following pressure test.
A-1.10.3.1 With the appliance valves off, open the cylinder supply valve. Close the cylinder supply valve. Observe the pressure gauge reading. The pressure indicated should remain constant for not less than three minutes. If any leakage is indicated by a drop in pressure, check the entire system with a leak detection fluid or detergent solution to locate the leak. Test solutions shall be noncorrosive and non-toxic.
Repairs shall be made before retesting and operating the system.
