JUMP TO FULL CODE CHAPTER
Initial cross-connection tests for plastic vacuum piping systems shall be conducted as follows:
  1. Tests shall be conducted to determine that no cross connections exist between any Category 3 plastic vacuum piping systems or Category 3 copper piping systems.
  2. The vacuum source shutoff valves for the vacuum piping systems shall remain closed during the tests, unless they are being used for the cross-connection test vacuum source.
  3. The cross-connection test vacuum shall be a minimum of 12 inch (305 mm) HgV.
  4. The source of test vacuum shall be connected only to the vacuum piping system being tested.
  5. The individual gas-powered device system gas outlets and vacuum system inlets shall be checked to determine that the test vacuum is only present at the vacuum piping system being tested.
  6. The cross-connection tests shall be repeated for each installed vacuum system with plastic piping.
  7. The proper labeling and identification of system outlets/inlets shall be confirmed during the tests. [NFPA 99:5.3.12.2.7]
