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.
16.2.1.4: Modifications affecting 20 or fewer sprinklers shall not require testing in excess of
system working pressure.
CONCEALED SPACES: - Section 8.14.1

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
