4.2.5 CERTIFICATION
The manufacturer shall furnish to the purchaser certified copies of the results of the tests on
each lot or shipment and size of conduit ordered, prior to payment. The certified test report
shall state the lot or control number and manufacturer of compound used and shall give
specific test values for compound tests, stiffness test, and tests having other than a simple
Pass/Fail result. Any conduit tested by the City that does not yield results consistent with the
certified test reports for that lot or shipment will be sufficient reason for rejection of the entire
lot or shipment. City of Fort Collins purchase order number shall be noted on the first page of
each report. Copies shall be sent to the Design section of Fort Collins Light & Power.
Unsigned copies are not acceptable even if accompanied by a signed cover letter.
5.0 PREPARATION FOR DELIVERY
Conduit shall be bundled by individual size into units suitable for shipping and stacked
storage.
To protect the bells from deformation caused by pressure from adjacent conduits, each bundle
shall be assembled such that bells are all at the same end of the bundle with the bell ends of
alternating layers recessed at least the full length of the bells in adjacent layers. The bundles
shall be secured using two steel bands with 2" x 4" minimum wooden boards under the bands,
sets of bands and boards to be spaced appropriately along the length of the bundle forming
adequate crate frames to provide the vertical stacking, frame to frame, to minimize stacked
storage deformation with the stack height up to ten feet. Direct contact between the steel
bands and the conduit anywhere on the perimeter of the bundle is expressly prohibited.
Bundles shall be shipped on an open bed truck.

3.1.2 Virgin compound is defined as compound which has not previously been used to make another
product. Reworked material is defined as clean reground or repelletized material generated from a
manufacturer's own conduit extrusion, and used by the same manufacturer who generates it.
Clean is considered to exclude anything foreign to the specific compound designated by the
manufacturer for use under this Specification. Rework material ma} be used provided that the
conduit or fittings produced meet all of the requirements of this Specification.
3. 1.3 CONDUIT TYPE
Conduit type shall be as specified in Specific Requirements for Design.
3.1.4 WORKMANSHIP
The conduit shall be homogeneous throughout and free from visible cracks, holes, foreign
inclusions, or other injurious defects. The conduit bore shall be smooth and free from blisters,
nicks or other imperfections which could mar conductors or cables.
3.1.5 SUNLIGHT RESISTANCE/COLOR
The conduit shall contain titanium dioxide pigment to produce a white color with a reflective
factor of greater than eighty percent to allow outdoor storage andior installation at 5.000 feet
altitude for an indefinite period without deterioration.

3.2.2 BELLED ENDS
Each length of conduit shall have an integral belled end. Glued couplings are specifically
prohibited. Belled end dimensions shall be based on the clearance fit system defined in Table 2
of ASTM F512 except socket depth and out -of -round requirements shall be in accordance with
Table III of this Specification. Belled ends shall be centered on the longitudinal axis to provide a
visible shoulder around the entire circumference of the conduit. Both ends of each length of the
conduit shall be perpendicular to the longitudinal axis of the conduit. i.e., both ends shall be
