PART 3 - EXECUTION
3.1 GENERAL
A. Instrumentation used for testing shall have been calibrated within the last six-month prior to
beginning work in this Section.
B. Inform the Owner's Representative in writing a minimum of five days prior to requested test.
C. Prior to testing, piping shall be inspected over its entire length and all obstructions removed.
D. Tests of concealed piping must be made before the piping is concealed. Pipes shall be proven
tight in the presence of an authorized representative of the Owner.
E. Install strainers as may be required to properly protect equipment from sediment or debris in the
transported media that could damage equipment. Where permanent strainers are not shown,
temporary strainers shall be required for use during the start-up period.
F. Devices connected to the system which cannot assume test pressures shall be disconnected and
protected from damage, individually tested and reconnected.
G. Provide a written report of tests. Forward the report to the Engineer and Owner within one week
after completion of the test. The report shall include the signature of the witnessing authorized
representative of the Owner acknowledging the test. Should portions of a piping system be
individually tested, prepare one final test report consolidating all piping section reports into one
final test report stating all piping was successfully tested. Test reports of partial system testing will
not be accepted. This report shall be completed by the Contractor and forwarded to the Engineer.
This final report shall state that all piping was successfully tested. A copy of the final test report(s)
and certificates shall be included within the Operating and Maintenance Manuals. The test report
form shall be as appended and typed on the Contractor's letterhead.
H. Additional tests may be specified in other sections. The tests specified in other sections shall be
performed in addition to tests performed under this Section.
I. Perform testing as required by applicable state and local codes, governing bodies, and the
Owner's insuring company over and above the requirements of this Specification.
J. Provisions shall be made so that every item may be thoroughly inspected and, in no case, shall
any part of construction be obscured.
K. Do not apply test pressures to "live" or "hot" valves. In the event such testing is necessary, install
temporary block ahead of the valve. The final test of the connection shall be by examination of
work under the service pressure.
L. Parts of the system under test shall be under constant supervision with authority to bleed off
excessive pressure that may develop. No test shall remain on work unless continuously attended.
M. Fluids shall circulate and flow freely without noise, vibration, or hammer on either hand or
automatic control, with no evidence of leaks, trapping, or binding.
N. Leaks shall be repaired immediately and the tests repeated until the systems are proven tight.
