Test Requirements for Service Lines

§ 192.511 Test Requirements for Service Lines#

(a)Each segment of a service line (other than plastic) must be leak tested in accordance with this section before being placed in service. If feasible, the service line connection to the main must be included in the test; if not feasible, it must be given a leakage test at the operating pressure when placed in service.#

(b)Each segment of a service line (other than plastic) intended to be operated at pressure of less than 1 p.s.i. (6.9 kPa) gage shall be given a leak test at a pressure of 10 p.s.i. (69 kPa) gage. This test shall be conducted with a 3 inch (76 millimeters) dial gauge with a maximum scale of 30 p.s.i. (207 kPa) gage. This test may be conducted with a mercury gauge capable of testing to 10 inches (254 millimeters) of mercury.#

(c)Each segment of a service line (other than plastic) intended to be operated at a pressure of at least 1 p.s.i. (6.9 kPa) gage but not more than 40 p.s.i. (276 kPa) gage must be givena leak test at a pressure of not less than 50 p.s.i. (345 kPa) gage on a 100 p.s.i. (689 kPa) gage scale gauge.#

(d)Each segment of a service line (other than plastic) intended to be operated at pressures of more than 40 p.s.i.g. must be tested to at least 90 p.s.i.g. on 100 p.s.i.g. scale gauge, except that each segment of a steel service line stressed to 20 percent or more of SMYS must be tested in accordance with § 192.507.#

(e)The test procedure used must reasonably ensure discovery of leaks in the segment being tested.#
