prior to the final test.
e.
The Contractor has provided written notification to the
Contracting Officer, at least [21] [_____] days prior to date of
Final Test, that preliminary tests have been successfully
completed.
3.6.1.2
Videotaping
Contractor shall videotape the tests in VHS format and shall record the
date and time-lapse, in seconds, from start to finish of each portion of
the test as directed by the Contracting Officer. Four copies of the tape
shall be submitted before the system will be considered accepted.
3.6.1.3
Manufacturer's Services
Experienced technicians regularly employed by the Contractor in the
installation of the system and manufacturer's representative referred to
elsewhere in this specification shall conduct the testing.
3.6.1.4
Materials and Equipment
Contractor shall provide AFFF concentrate, gauges, AFFF sample collection
apparatus, instruments, hose, personnel, elevating platforms, scaffolding,
ladders, appliances and any other equipment necessary to fulfill testing
requirements specified.
3.6.1.5
Facility and Environmental Protection
Contractor shall provide protection for the facility, including electrical
and mechanical equipment exposed to possible damage during discharge tests.
This shall include provision of sandbags or similar means for preventing
migration of foam solution into adjacent areas. Temporary measures shall
be provided to prevent AFFF solution from entering storm drains, sanitary
sewers, drainage ditches, streams and other water sources. Discharged AFFF
shall be contained on paved surfaces and shall not be allowed to come in
contact with the earth.
3.6.2
Control System Tests
Operational features of the control system shall be tested and
demonstrated. This shall include testing of control panels and each input
and output circuit. Tests of circuits shall include actuation and
simulated circuit fault at each initiating, notification, supervisory and
actuation device or appliance. As a practical matter, these tests shall be
a repeat of preliminary tests required under paragraph PRELIMINARY TESTS.
3.6.3
AFFF Proportioning System Tests
Each AFFF proportioner (ratio controller) shall be flow tested to determine
that proportioning accuracy is within specified limits. Each proportioner
supplying sprinkler systems with closed heads shall be tested at two flow
rates; the minimum flow rate specified in the manufacturer's published data
and a flow rate at least four times the minimum. Each proportioner
supplying a deluge system or a nozzle system shall be tested at the design
flow rate. Collecting AFFF samples from each proportioner shall be
accomplished in accordance with NFPA 16, and the approved test plan. Foam
solution concentrations shall be determined using the methods outlined in
NFPA 16. Proportioning for nominal 3 percent concentrate shall be between
