NOTE: Coordinate with Division 1 concerning the
availability of water and electric power.
**************************************************************************
Field [inspections, field] tests, and trial operations specified in this
section shall be performed by the Contractor. The Contractor shall provide
gas, oil, labor, equipment, and incidentals required for testing[, except
that in accordance with Division 1 the Government will provide water or
electric power required for tests]. The Contractor shall give the
Contracting Officer [_____] days' advance written notice of the dates and
times scheduled for tests and trial operations.
3.2.1
Field Inspections
Inspect piping system prior to initial operation, for conformance to
drawings, specifications, and ASME B31.1. Equipment, material, or work
rejected because of defects or non-conformance with drawings,
specifications, and ASME B31.1 shall be replaced or corrected by the
Contractor, as directed by the Contracting Officer.
3.2.2
Field Tests
Conduct the following tests after completion of the piping installation and
prior to initial operation.
3.2.2.1
Piping System
Test piping system hydrostatically using water not exceeding 38 degrees C
100 degrees F. Conduct tests in accordance with the requirements of ASME
B31.1 and as follows. Test the piping system after the lines have been
cleaned as herein specified and before any insulation covering has been
applied. Test piping system at 1 1/2 times the system pressure or 345 kPa
(gage) 50 psig whichever is greater. Before performing tests, remove or
valve off from the system, gages, traps, and other apparatus which may be
damaged by the test pressure. Install a calibrated test pressure gage in
the system to observe any loss in pressure. Maintain the required test
pressure for a sufficient length of time to enable an inspection to be made
of joints and connections. Perform tests after installation and prior to
acceptance.
3.2.2.2
Start-Up and Operational Test
Start-up the system and initially operate with components operating. During
the test, periodically clean the various strainers until no further
accumulation of foreign material occurs. Exercise care so that minimum
loss of [water] [steam] occur when strainers are cleaned. Adjust safety
and automatic control instruments as necessary to place them in proper
operation and sequence.
3.2.2.3
Extent of Field Tests
After installation and before acceptance, subject the work of this section
to necessary field tests, including those herein specified, and in Section
15950N HVAC TESTING/ADJUSTING/BALANCING.
