feet altitude, and for underground use by direct burial or encasement in concrete.
2 APPLICABLE DOCUMENTS
This Specification is in accordance with the requirements of ASTM F512, titled "Standard Specification for
Smoothwall Polyvinyl Chloride (PVC) Conduit and Fittings for Underground Installation", with exceptions as noted
in the following paragraphs.
3 REQUIREMENTS
3.1 GENERAL REQUIREMENTS FOR DESIGN
All conduit furnished under this Specification shall, unless otherwise specified, comply with ASTM F512. In
case of conflict, the requirements of the following documents shall apply in the priority shown:
This Specification.
ASTM F512.
Other referenced standards.
3.1.1 MATERIAL
Conduit furnished under this Specification shall be made of virgin polyvinyl -chloride (PVC)
compound conforming to ASTM D1784 with the minimum cell classification shown in Table I of this
Specification. Chemical resistance shall be in accordance with ASTM D1784, suffix A or B.

3.1.2 COMPOUND
Virgin compound is defined as compound, which has not previously been used to make another
product. Reworked material is defined as clean reground or re -pelletized materials 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 may 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 and/or installation at 5,000 feet altitude for an
indefinite period without deterioration.
3.1.6 LENGTH
Conduit shall be in lengths of twenty feet overall including integral bell. Tolerance of length shall be t
one inch (t 25 mm).
3.2 SPECIFIC REQUIREMENTS FOR DESIGN
3.2.1 CONDUIT DIMENSIONS AND TOLERANCES
Dimensions, tolerances and pipe stiffness shall be in accordance with Table II of this Specification.
Wall thicknesses shown in Table Il are based on a minimum modulus of 500,000 psi.

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 square cut.

4 QUALITY ASSURANCE
4.1 RESPONSIBILITY FOR INSPECTION
Unless otherwise specified, the vendor is responsible for the performance of all tests and inspection
requirements specified herein. Except as otherwise specified, the vendor may utilize his own facilities or any
commercial laboratory acceptable to the City of Fort Collins. The City reserves the right to perform or witness
any of the tests and inspections set forth in this Specification, where such inspections are deemed necessary.
If the City, upon receipt of the conduit, deems it necessary to have an independent laboratory perform tests
and inspections set forth in this Specification, the manufacturer shall be responsible for all fees incurred in
testing if any requirement of the specifications is not met and/or test results for that lot or shipment are not
consistent with the manufacturer's certified test results.
4.2 REQUIREMENTS AND TEST METHODS
4.2.1 COMPOUND TESTS
All the tests required by ASTM D1784, except the chemical resistance test, shall be made on a
compound sample from each new lot or batch. The average value for all the tests made on each batch
or lot shall comply with the requirements of paragraph 3.1.1 of this Specification and shall be reported
in the certified test report. The chemical resistance test shall be performed annually or when
compound suppliers are changed and test results shall be included in the certified test report.
4.2.2 SUNLIGHT RESISTANCE TESTS
Evidence that the compound being used has been qualified in accordance with all tests required by
Paragraph 17 of UL 651 shall be included in the certified test report.
4.2.3 PERFORMANCE TESTS
Conduit furnished under this Specification shall pass all tests required by and performed in accordance
with ASTM F512 except 2-inch conduit shall have a minimum impact resistance of 40-foot-pounds at
32-F (0°C).

366-200
Rev. Sym. H
4.2.4 EXTRUSION QUALITY TEST
The extrusion quality shall be determined by immersion in anhydrous acetone in accordance with
ASTM D2152. Finished duct shall not flake or disintegrate when subjected to this test.
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 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.
