Standard Specification for 3.25-in. Outside Diameter Poly(Vinyl Chloride) (PVC) Plastic Drain, Waste, and Vent Pipe and Fittings
SCOPE
1.1 This specification covers requirements and test methods for materials, dimensions and tolerances, deflection load, crush resistance, hydrostatic-burst resistance, flattening resistance, impact resistance, and solvent cement. A form of marking is also included. Plastic which does not meet the material requirements specified in Section 5 is excluded.
Note 1—This specification was formerly issued under the title, 3-in. Thin Wall Poly(Vinyl Chloride) (PVC) Plastic Drain, Waste, and Vent Pipe and Fittings.
Note 2—Techniques for making solvent-cement joints are given in Practice D 2855.
1.2 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 The following precautionary caveat pertains only to the test methods portion, Section 7, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

4. Significance and Use
4.1 The requirements of this specification are intended to provide pipe and fittings suitable for drainage of sewage and certain

4.2 When joining 3.25-in. outside diameter PVC DWV piping to 3-in. Schedule 40 PVC DWV piping, it is necessary to use
either reducer bushings or increasers, as shown in the tables at the end of the text, due to the differences in pipe outside diameters.
NOTE 3—Industrial waste disposal lines should be installed only with the specific approval of the cognizant building code authority since chemicals
not commonly found in drains and sewers, and temperatures in excess of 160°F (70°C), may be encountered.

6.4 Minimum Hydrostatic Burst Pressure— When tested at 73°F (23°C) in accordance with 7.5, the minimum burst pressure
of pipe shall be 500 psi (3.45 MPa) and the minimum burst pressure of fittings shall be 200 psi (1.38 MPa).

NOTE 5—Theminimumburstpressureforfittingsarelowerthanthatforpipebecausethegeometryissuch,particularlyareaandradii,thatthestresses
produced in the wall of the fitting are higher than those produced in pipe tested at the same internal pressures. This requirement is intended only for the
purpose of quality control to ensure that the pipe and fittings have no weak areas, particularly at flow and weld lines.
6.5 Flattening Resistance—The average decrease in inside diameters of pipe and fittings shall not exceed 10% when tested in
accordance with 7.6 (Note 3).
6.6 Impact Resistance—The minimum impact resistance, when tested at the time of manufacture, shall be 50 ft·lbf (6.91 J) at
73°F (23°C) and 25 ft·lbf (3.46 J) at 32°F (0°C) for pipe and 20 ft·lbf (2.77 J) at 73°F and 10 ft·lbf (1.38 J) at 32°F for fittings.
Test in accordance withTest Method D2444 usingTup C and HolderAfor pipe andTupAand Holder B for fittings. Use a 12-lb
(5-kg) tup for testing pipe and fittings. Test couplings cemented to short pieces of pipe and allowed to dry for 24 h.
6.6.1 Test 10 specimens. When 9 or 10 specimens pass, accept the lot. When 2 or more specimens fail, test 10 additional
specimens.When17of20specimenstestedpass,acceptthelot.When4ormoreof20specimensfail,test20additionalspecimens.
When 32 of 40 specimens pass, accept the lot. When 9 or more of 40 specimens fail, the lot does not meet the requirements of
this specification.
6.6.2 Failure of the test specimen shall be shattering or any crack or break extending entirely through the pipe wall and visible
to the unaided eye.
6.7 Threads—For all fittings having taper pipe threads, threads shall conform to Specification F 1498 and be gaged in
accordance with 7.7.
6.8 Extrusion Quality—The pipe shall not flake or disintegrate when tested in accordance with Test Method D2152.
7. Test Methods
7.1 Sampling—Take a random sample from each lot or shipment of the pipe and fittings sufficient to determine conformance
with this specification.About 40 ft (12 m) of pipe are required to make the tests prescribed.The number of fittings required varies
depending on the size and type of fitting.
