The plan review was performed under the State of Oregon Structural Specialty Code (OSSC) 2004
edition, Oregon Fire Code 2004 edition; and NFPA 13. The submitted plans are approved subject to
the following.
• HYDROSTATIC TESTING
Hydrostatic testing of the system shall occur at sprinkler final. The contractor's material and test
certificate required by NFPA 13, 16.1 shall be completed and signed by both the installer and
building owner.
TESTING: - Section 16.2.1
1. Unless permitted by 16.2.1.2 through 16.2.1.6, all piping and attached appurtenances
subjected to system working pressure shall be hydrostatically tested at 200 psi (13.8 bar) and •
shall maintain that pressure without loss for 2 hours. Loss shall be determined by a drop in
gauge pressure or visual leakage. The test pressure shall be read from a gauge located at the
• low elevation point of the system or portion being tested.
*16.2.1.2: Portions of systems normally subjected to system working pressures in excess of 150 psi
(10.4 bar) shall be tested as described in 10 - 2.2.1 at a pressure of 50 psi (3.5 bar) in excess of system
working pressure.
*16.2.1.4: Modifications affecting 20 or fewer sprinklers shall not require testing in excess of system
working pressure.

be modified as specified in the individual product listings.
SWAY BRACING: - Section 9.3.5 - 9.3.5.8
16. The system piping shall be braced to resist both lateral and longitudinal horizontal seismic
loads and to prevent vertical motion resulting from seismic loads. The structural components
to which bracing is attached shall be determined to be capable of carrying the added applied
seismic loads. Sway braces shall be designed to withstand forces in tension and compression.
Bracing shall be attached directly to feed and cross mains.
SPARE SPRINKLERS: - Section 6.2.9
17. The stock of spare sprinklers shall include all types and ratings installed and shall be as
follows:
