Specifications - Lord and Son Construction, Inc.

. Temperatures between 120 and 400 degrees F: Apply two coats of 400
degrees F heat-resisting enamel applied to a total minimum thickness of
two mils to metal surfaces subject to temperatures between 120 and 400
degrees F.
c. Temperatures greater than 400 degrees F: Apply two coats of 315
degrees C 600 degrees F heat-resisting paint applied to a total minimum
dry film thickness of two mils to metal surfaces subject to
temperatures greater than 400 degrees F.
3.8 IDENTIFICATION SYSTEMS
Provide identification tags made of brass, engraved laminated plastic, or
engraved anodized aluminum, indicating service and item number on all valves
and dampers. Provide tags that are 1-3/8 inch minimum diameter with stamped
or engraved markings. Make indentations black for reading clarity. Attach
tags to valves with No. 12 AWG 0.0808-inch diameter corrosion-resistant
steel wire, copper wire, chrome-plated beaded chain or plastic straps
designed for that purpose.
3.9 DAMPER ACCEPTANCE TEST
Submit the proposed schedule, at least 2 weeks prior to the start of test.
Operate all fire dampers and smoke dampers under normal operating
conditions, prior to the occupancy of a building to determine that they
function properly. Test each fire damper equipped with fusible link by
having the fusible link cut in place. Test dynamic fire dampers with the
air handling and distribution system running. Reset all fire dampers with
the fusible links replaced after acceptance testing. To ensure optimum
operation and performance, install the damper so it is square and free from
racking.
3.10 TESTING, ADJUSTING, AND BALANCING
The requirements for testing, adjusting, and balancing are specified in
Section 23 05 93 TESTING, ADJUSTING AND BALANCING FOR HVAC. Begin testing,
adjusting, and balancing only when the air supply and distribution,
including controls, has been completed, with the exception of performance
tests.
3.11 PERFORMANCE TESTS
After testing, adjusting, and balancing is complete as specified, test each
system as a whole to see that all items perform as integral parts of the
system and temperatures and conditions are evenly controlled throughout the
building. Record the testing during the applicable season. Make
corrections and adjustments as necessary to produce the conditions indicated
or specified. Conduct capacity tests and general operating tests by an
experienced engineer. Provide tests that cover a period of not less than
days for each system and demonstrate that the entire system is functioning
according to the specifications. Make coincidental chart recordings at
points indicated on the drawings for the duration of the time period and
record the temperature at space thermostats or space sensors, the humidity
at space humidistats or space sensors and the ambient temperature and
humidity in a shaded and weather protected area.
