3.09 TESTING, INSPECTION AND ACCEPTANCE
A. MATERIAL TESTING
1.
All material testing shall be performed by a registered independent, third-
party laboratory, and paid for by the Contractor.
The Contractor shall provide test results of the short term properties of the
cured lining material in the quantity of one test per liner batch, or 3,000 feet of
installed liner, or as required by the Owner. The liner shall be in compliance
with the physical properties described in these Specifications. Flexural
strength and modulus shall be tested in accordance with the requirements of
ASTM D 790.
B. INSPECTION
C.
D.
1.
After the work is completed, the Contractor shall inspect the pipeline by
closed circuit color television inspection and shall provide the Engineer with
one copy of a videotape or acceptable digital format recording of this
inspection log for the Owner’s records. Any repaired areas shall be re-
televised.
FIELD TEST (THICKNESS)
1.
Remove the CIPP liner material from the host pipe core samples. Remove
any inner liner film, pre-liner and resin that is not contained within the tube.
Measure the liner thickness at three spots on each sample. The resulting six
measurements will be averaged. The average thickness shall be equal to or
greater than the required thickness for the particular section. No undersize
allowance is permitted. In accordance with D 790-03, referenced in ASTM
1216, the calculated wall thickness refers only to the part of the liner that
consists of a saturated tube. Elements that are not part of the saturated tube do
not contribute to the structural integrity of the liner, thereby excluding tube
that is not fully saturated or portions of resin without the tube carrier.
ACCEPTANCE
1.
Prior to final acceptance, any defects that may affect the integrity or strength
of the pipeline is the opinion of the Engineer shall be repaired by the
Contractor at no additional cost to the Owner.
. Pipeline shall be true to line and grade, with no visual bulges, sags,
protrusions, deflections, offset joints, leaking joints, or other visible
infiltration, or other defects that would impair the intended use of the
completed pipeline.
