g. Identification and Labeling: The Contractor shall supply
identification tags or labels for each cable. The labeling format
shall be identified and a complete record shall be provided to the
Government with the final documentation. Each cable shall be
identified by type of signal being carried and termination points. All
labels shall be non-fading when exposed to moisture, sunlight, soil
minerals, chemicals, and other environmental elements.
h. Design Parameters
**************************************************************************
NOTE: The designer will include the data listing,
the loading conditions, including radial thickness
of ice, horizontal wind pressure, and temperature,
for both combined ice and wind loading and extreme
wind loading encountered at the project site.
**************************************************************************
The following conditions to be encountered at this installation are as
follows:
aa. Combined Ice and wind loading:
(1) radial thickness of ice [_____] mm inch
(2) horizontal wind pressure [_____] Pa psf
(3) constant to be added to the resultant [_____] N/m lb/ft
bb.
Extreme wind loading:
(1) velocity pressure exposure coefficient, wire [_____]
(2) basic wind speed [_____] m/s mi/h
(3) gust response factor, wire [_____]
(4) importance factor [1.0] [_____]
(5) shape factor [1.0] [_____]
3.2
TESTING
The Contractor shall provide all personnel, equipment, instrumentation, and
supplies necessary to perform all testing.
3.2.1
Wire Line Test
The Contractor shall test each wire line pair. The Contractor shall
prepare reports containing test results and shall certify in the reports
conformance to the following requirements.
3.2.1.1
Attenuation
Measurements shall be made with test tone of 1004 Hz at 0 dBm. Attenuation
distortion not to exceed minus 3 dB to plus 12 dB from 300 to 3,000 Hz, and
minus 2 dB to plus 8 dB from 500 to 2,500 Hz referenced to the attenuation
of the 1004 Hz test tone. Attenuation at 1004 Hz of less than 40 dB.
3.2.1.2
Envelope Delay
Envelope delay distortion shall be no greater than 1,750 microseconds over
a range of 800 to 2,600 Hz.
