5.2.3 Solvent Cement Bell Dimensions—The bell dimen-
sions and tolerances shall be as shown in Table 5 and Table 6
when measured in accordance with Test Method D2122.
5.3 Qualification Tests—These tests are for qualification of
the compound and extrusion process, not for quality control.
5.3.1 Sustained Pressure—The sustained pressure test shall
be completed for each diameter at initial start-up. Thereafter, it
shall be completed whenever there is a change in the ER
(3.3.1), or the WTR (3.3.4), or whenever a change is made to
the compound which is outside the allowable limits of the
Plastics Pipe Institute PVC Range Composition (see PPI
TR-2). The pipe shall not fail, balloon, burst, or weep as
defined in Test Method D1598 at the test pressures given in
Table 7 when tested in accordance with 6.4.
5.3.2 Regression Test—This test shall be completed on a
representative diameter at initial start-up. A representative
diameter is one which has an ER, a WTR, and a compound
which is the same as the other diameters manufactured.
Thereafter, it shall be completed on a representative diameter
whenever there is a change in the ER or the WTR, or whenever
a change is made to the compound which is outside the
allowable limits of the Plastics Pipe Institute PVC compound
range formula (see PPI TR-3). The test shall be conducted in
accordance with 6.5.
5.3.2.1 The pipe shall demonstrate a minimum hydrostatic
design basis projection, at the 100 000-h intercept, of 6810 psi
(46.92 MPa) (for Hydrostatic Design Basis Categories, see
Table 1 of Test Method D2837).
5.3.3 Long-Term Hydrostatic Strength Test for Solvent Ce-
mented Joints—Solvent cemented joints of pipe shall be
assembled in accordance with Specification D2855 instructions
for joining of PVC pipe and fittings, and tested for long- term
hydrostatic strength for each diameter at initial start-up.
Thereafter, it shall be completed whenever there is a change in
the ER (3.3.1), or the WTR (3.3.4), or whenever a change is
made to the compound which is outside the allowable limits of
the Plastics Pipe Institute PVC compound range formula (see
PPI TR-3). The joint shall not fail, balloon, burst, weep, leak or
pull apart while subjected to a sustained pressure of 2 times the
pressure rating of the pipe for continuous service for 1000
hours at at 73 °F 64 °F (23 °C 62 °C).
5.4 Quality Control Tests—These tests are intended to
ensure the quality of the finished pipe product.
5.4.1 Burst Pressure—The minimum burst pressure for
PVCO pipe shall be as given in Table 8, when determined in
accordance with 6.6.
5.4.2 Flattening—There shall be no evidence of splitting,
cracking, or breaking when the pipe is tested in accordance
with 6.7.
5.4.3 Extrusion Quality—The starting stock pipe shall not
flake, crack, or disintegrate when tested in accordance with
Test Method D2152.
5.4.4 Impact Resistance—The minimum impact resistance
for PVCO shall be as given in Table 9, when determined in
accordance with 6.8.
NOTE 1—The impact resistance test is intended for use only as a
quality-control test, not as a simulated service test. This test has been
found to have no quality-control significance in sizes over 12 in. (300
mm).
5.4.5 Workmanship, Finish, and Appearance—The pipe
shall be homogeneous throughout and free from visible cracks,
holes, foreign inclusions, or other defects. The pipe shall be as
uniform as commercially practicable in color, opacity, density,
and other physical properties.
NOTE 2—Color and transparency or opacity should be specified in the
contract or purchase order.
6. Test Methods
6.1 Conditioning—Condition the test specimen at 73 °F 6
4 °F (23 °C 62°C) and 50 % 65 % relative humidity for not
less than 40 h prior to test in accordance with Procedure A of
Practice D618 for those tests where conditioning is required.
6.2 Test Conditions—Conduct the tests in the standard
laboratory atmosphere of 73 °F 64 °F (23 °C 62 °C) and
50 % 65 % relative humidity, unless otherwise specified in
the test methods or in this specification.
6.3 Sampling—The selection of the sample or samples of
pipe shall be as agreed upon between the purchaser and the
seller. In case of no prior agreement, the sample selection of the
manufacturer shall be deemed adequate.
6.3.1 Test Specimens—Not less than 50 % of the test speci-
mens required for any pressure test shall have at least a part of
the marking in their central sections. The central section is that
portion of pipe which is at least one pipe diameter away from
an end closure.
6.4 Sustained Pressure Test—Select the test specimens at
random. Test individually with water at the internal pressure
given in Table 7, six specimens of pipe, each specimen shall be
3ft long (1000 mm) between end closures and bearing the
permanent marking on the pipe. Maintain the specimens at the
pressure indicated for a period of 1000 h. Hold the pressure as
closely as possible, but within 610 psi (670 kPa). Condition
the specimens at the test temperature of 73 °F 64 °F (23 °C 6
2 °C).
