1318.11 Standing Pressure Tests — For Category 3 Gas Powered Device Distribution Piping

Uniform Plumbing Code 2018 of Nevada > 13 Health Care Facilities and Medical Gas and Medical Vacuum Systems > 1318.0 Testing and Inspection > 1318.11 Standing Pressure Tests — For Category 3 Gas Powered Device Distribution Piping
JUMP TO FULL CODE CHAPTER
After successful completion of the initial pressure tests under Section 1318.8.7, Category 3 gas-powered device distribution piping shall be subjected to a standing pressure test, which includes the following:
  1. Tests shall be conducted after the installation of outlet valves and other distribution system components (e.g. pressure indicators and line pressure relief valves).
  2. The source valve shall be closed unless the source gas is being used for the test.
  3. The piping systems shall be subjected to a 24 hour standing pressure testing using oil-free, dry nitrogen NF or the system gas.
  4. Test pressures shall be 20 percent above the normal system operating line pressure.
  5. At the conclusion of the tests, there shall be no change in the test pressure greater than a gauge pressure of 5 psi (34 kPa).
  6. Leaks, if any, shall be located, repaired (if permitted), or replaced (if required), and retested. [NFPA 99:5.3.12.2.9]
