Pipe lines shall be pressure tested in presence of the CQA Consultant.
CONTRACTOR to provide ENGINEER with a minimum of 7 days’ notice
before performing the test.

Provide necessary connections between section of pipe being tested and
nearest available source of water or air supply, together with test
pressure equipment, meters, pressure gauge, other equipment, materials
and facilities necessary to make specified tests.

Owner will provide a source of water for testing.

Before butt fusing pipe, inspect each length for presence of dirt, sand,
mud, shavings, and other debris or animals. Remove debris from pipe.

Cover open ends of fused pipe at end of each working day. Cap to
prevent entry by animals or debris.

PART 3 - EXECUTION

3.1 FIELD QUALITY CONTROL

A. Pipe may be rejected for failure to conform to any of the following:

1.

We WN

Fractures or cracks passing through pipe wall, except single crack not
exceeding 2 inches in length at either end of pipe which could be cut off
and discarded. Pipes within one shipment shall be rejected if defects
exist in more than 5 percent of shipment or delivery.

completed within 2 to 5 minutes. Remove the load, and examine the
specimens for splitting cracking or breaking.

2. Pipe Ring Stiffness Constant: The pipe ring stiffness constant shall be
determined using procedures similar to those outlined in ASTM D2412.
The stiffness of HDPE pipe is defined in terms of the load, applied
between parallel plates, which causes 1 percent reduction of pipe
diameter. Test specimens shall be a minimum of two pipe diameters or 4
feet in length, whichever is less.

2.4 GASKETS AND HARDWARE

e. Production Code, including Extrusion Date, and Lot or Batch
Number; and
f. SDR.

2.3 SOURCE QUALITY CONTROL

A. The pipe and fitting manufacturer shall certify that samples of his production
pipe have undergone stress regression testing, evaluation, and validation in
accordance with ASTM D2837 and PPI TR-3. Under these procedures, the
minimum hydrostatic design basis shall be certified by the pipe and fitting
manufacturer to be 1600 psi at 73.4°F and 800 psi at 140°F.

E. Clean rework or recycled material generated by the manufacturer’s own
production may be used so long as the pipe or fittings produced meet all the
requirements of this Section.

2.2 PIPE AND FITTINGS

A. Dimensions

1. The nominal inside diameter of the pipe shall be true to the specified pipe
size in accordance with ASTM D2513. Standard laying lengths shall be 40
feet + 2 inches.

2. Fittings such as couplings, wyes, tees, adaptors, etc. for use in laying pipe
shall have standard dimensions that conform to ASTM D2513.

C. Pipe Handling

1. Protect pipe from excessive heat or harmful chemicals.
2. Handle pipe and use equipment needed to avoid gouging of the pipe

surfaces.

PART 2 - PRODUCTS

2.1

PHYSICAL PROPERTIES

A. Materials used for the manufacture of HDPE pipe and fittings shall meet the
following physical property requirements:

C. QA testing for representative pipe and fitting samples shall include:

Test Standard Pipe Fittings
