Three speciments, each 6 ±1/8 inches long, shall be test- ed. The ends shall be cut square and free of burrs and jagged edges. (This test is intended only for use as a quality control test, not for use as a simu- lated service test.) 6-3.2 Fittings Requirement - Individual fittings unassem- bled shall withstand a minimum load of 650 pounds without cracking or other visible evidence of failure. Three complete fittings shall be tested. Fittings having non-uniform diameters such as reducers, shall be considered acceptable when the wall thickness at all points is equal to or greater than the wall thickness of pipe of the same ma- terial and diameter that meets the crush resist- ance requirements. (This test is intended only for use as a quality control test, not for use as a simu- lated service test.) 6-3.3 Deflection load and crush resistance Test Method -The deflection load and crush resistance of pipe and fittings shall be measured by the following method: A short length of pipe or a fitting is loaded between two rigid parallel flat plates at a controlled rate of approach to one an- other. In the test for pipe: the load, when the ini- tial diameter is reduced 15 percent, shall be noted (deflection load.). The test shall be continued until the diameter is deflected to 60 percent of its orig- inal value (crush resistance). 6-3.3.1 Apparatus -The apparatus shall con- sist of the following: • 0 a) Testing Machine —A properly calibrated compression testing machine of the constant -rate - of -crosshead -movement type meeting the require- ments of Section 4 (a) in ASTM D695 -61T shall be used to make the tests. The rate of head ap- proach shall be 0.20 to 0.25 inch per minute. b) Loading Plates—The load shall be applied to the specimen through two parallel steel bearing plates. The plates shall be flat, smooth (free from machining marks) and clean. The thickness of each plate shall be not less than 0.25 inch and the length not less than 6.5 inches. The width of each plate shall be not less than 1.5 times the outside diameter of the pipe specimen. c) Deformation (deflection) Indicator — The change in inside diameter or deformation (deflec- tion) parallel to the direction of loading shall be measured with a suitable instrument meeting the requirements of Section 4(d) in ASTM D695 -61T except that the instrument shall be accurate to the nearest 0.001 inch. The instrument shall not sup- port the pipe test specimen or affect in any way the load -deflection measurements. Alternatively, changes in outside diameter may be measured during loading by continuously recording plate travel in place of inside diameter measurements. 6-3.3.2 Procedure a) Starting at the thinnest wall location, measure the wall thickness to the nearest 0.001 inch at 45° intervals. At these same locations, measure the inside diameters to the nearest 0.01 •inch. The pipe length shall be measured to the nearest 0.01 inch. These measurements shall be made on each test specimen after conditioning. b) Locate pipe specimen with its axis parallel to the bearing plates and center it laterally in the testing machine. The line marking the thinnest wall of the specimen shall be either at the top or bottom bearing plate. c) Measure the vertical inside or outside di- ameter near the center with specimen in test posi- tion but not in contact with the upper plate. d) With deflection indicator in place, bring upper plate down to contact specimen with no more load than necessary to hold it in place. Re- cord any deflection. e) Specimen shall be compressed at a con- stant (vertical) deflection rate of 0.20 to 0.25 inch per minute. f) Terminate the test when the diameter of pipe test specimens is reduced to 40 percent of its original value or the pipe cracks or shows other evidence of visible failure. Terminate the test on fittings when the load reaches 750 pounds. g) Observe the load and deflection at the first evidence of cracking if any. Record location and type of failure. 6-3.3.3. Calculations — For pipe, divide the load in pounds at 15 percent deflection (deflection load) and also at failure (crush resistance) ; if •such occurred, by the length of the pipe test speci- men in feet to obtain the deflection load and crush resistance respectively in pounds per linear foot. Calculate the values for each specimen separately. 6-4 Minimum Hydrostatic Burst Pressure Requirement—The minimum burst pressure of pipe shall be in accordance with Table IV, and the minimum burst pressure of fittings shall be 200 psi'. . TABLE IV Minimum Hydrostatic Burst Pressure of Pipe at 23°C (73.4°F) Size, inch Burst Pressure' (min., psi) 11/.4 970 11/2 870 2 730 3 690 4 580 NOTE 1. The minimum burst pressures for fittings are lower than that for pipe because the geometry is such, particularly area and radii, that the stresses produced in the walls of the fitting are higher than those produced in pipe tested at the same internal pressures. (This re- quirement is intended only for the purpose of quality control to insure that the pipe and fittings have no weak areas, particularly at flow and weld lines. It is not in- tended for use as a simulated service test.) NOTE 2. These burst pressures are calculated in accord- ance with Tentative Recommended Practice for Calculat- ing Stress in Plastic Pipe under Internal Pressure (ASTM Designation: D2153 -63T) using a hoop stress of 5240 psi. This practice is based on the "ISO equation". Test Method—The test equipment and pro- cedure shall be as specified in Tentative Method of Test for Short Time Rupture Strength of Thermo- plastic Pipe, Tubing and Fittings (ASTM Desig- nation: D1599 -62T) . The test specimens shall be selected at random. Three specimens of pipe, each ten times the nominal diameter or a maximum of three feet in length, shall be tested. Three com- plete fittings shall be tested. The specimens shall be tested individually with water under pressure that is increased at an even rate to burst thespeci- men within a period of 60 to 90 seconds. One end of the pipe or fitting shall be rigidly fitted to the pressurizing apparatus and the other end shall be free but supported at the free end if necessary. Care shall be taken to remove all air from the pipe before capping and testing. Any suitable closure that is free of leaks at maximum pressure may be used. The specimen shall be conditioned at 23°C (73.4°F), for at least two hours before testing. The water temperature shall be within plus or minus 1.7°C (3.0°F) of the conditioning tempera- ture. 6-5 Sustained pressure Requirement—Pipe specimens shall be tested for 1,000 (+ 10-0) hours, and no crack, burst, leak or any type of failure shall develop during this test, and the outside diameter shall not increase more than five (5) percent of the measured initial outside diameter while under stress. Test Method—Equipment and test method shall be as specified in Tentative Method of Test for Time -to -Failure of Plastic Pipe Under Long - Term Hydrostatic Pressure, ASTM Designation: D1598 -58T. The test specimens shall be selected at random. Three (3) specimens of pipe each ten (10) times the nominal diameter in length or a maximum of three (3) feet and containing the permanent identification on the pipe shall be test- ed. These specimens shall be tested at a computed hoop stress of 2300 psi (using the ISO formula (d -t) S = p for a minimum of 1,000 hours and 2t not more than 1,010 hours at 73°F. If one (1) sample fails, three (3) additional samples shall be placed on test under the same conditions. Of the six (6) samples, five (5) shall pass in order that the pipe shall be considered acceptable. Water shall be used for the pressure medium. Any end fitting that fits the specimen without leakage or other failure may be used. 6-6 Bend -back test Requirement—Any cracking which shows up from the bend -back test constitutes failure. In this event, two new samples shall be selected and tested along the same portion of the circumference as that portion which failed. Failure of either of the additional samples will be cause for rejection. Test Method — Samples shall be selected at random and pre -conditioned for two hours at 73°F -- 3°. Four (4) specimen rings, each one (1) inch long shall be cut from each pipe sample. Each ring shall be cut axially as follows: cut one (1) ring at 12 o'clock and successive rings at 3, 6, and 9 o'clock respectively. Each of the sections is then opened outward and bent into a "U" shape with the inside surface turned out. 6-7 Chemical resistance Requirement—The pipe and fittings shall not increase in weight more than 0.50 percent and shall not change in deflection load and crush re- sistance more than ± 15 %. Test Method—The resistance to the following chemicals shall be determined in accordance with Tentative Method of Test for Resistance of Plas- tics to Chemical Reagents (ASTM Designation: D543 -60T) : The test specimens for pipe shall be six (6) inches long and cleanly cut. The fittings specimens shall consist of complete fittings. Three (3) speci- mens shall be tested with each reagent.

(b) Drop tube—The drop shall be made of cold -drawn seamless steel tubing with an inside diameter of 2.563 ± 0.003 inches; or of acryloni- trile -butadiene -styrene (ABS) or polyvinyl chlor- ide (PVC) plastic pipe, 21/2 inch nominal pipe size with a standard dimension ratio (SDR) of 21. Al- ternately, the tup may be dropped without a pro- tective tube provided other means are provided to protect the operator from the random rebound of the tup. It shall be sufficiently long (approximately 6 feet) to provide for a height of fall of at least 5 feet and shall be mounted so that the length- wise dimension is vertical as determined by a plumb bob. c) Tup hold and release—Means shall be pro- vided to hold the tup at steps of 1 -inch up to 5 feet above the pipe or fitting test specimen, as meas- ured from the bottom of the tup to the top of the specimen as mounted; to release the tup in a re- producible manner; to allow the tup to fall freely through the tube to strike the specimen; and to catch the tup on the first rebound. One type of device suitable for this test is shown in Figure 2. d) Specimen holder—The pipe specimen hold- er shall consist of a steel plate, 8 by 12 by 1 inch in which a V -groove to position the pipe specimen shall be cut. This V -groove shall be 1/8 -inch deep with an included angle of 120 degrees. The edges of the V -groove shall be rounded to 1/16 -inch. Fittings shall be laid on their side on a 0.50 -inch thick steel plate. Fittings that do not contact the steel plate directly under the point of impact shall be supported in this area by a steel shim or small steel plate. The specimen holders shall be mounted on a firm rigid base fastened to a heavy concrete slab. Means shall be provided to adjust the speci- men holders so that the specimens can be centered under the end of the drop tube. 6-11.2 Test specimens a) At least 6 pipe specimens shall be tested. 9 Specimen length shall be 6 ± 1/8 inches.

Unsymmetrical fittings shall be tested by lay- ing the specimen, on its side and impacting the other side at the geometrical center. Three speci- mens shall be struck on one side and three on the other. e) The test specimen shall be placed under the end of the drop tube so that the side of the pipe or fitting shall be struck by the tup on the geometrical center of the side. The 12 -pound tup shall be dropped from the height necessary to pro- vide the impact energy requirement given in Table IV. Each test specimen shall be subjected to only one impact blow. f) The impacted specimens shall be carefully examined visually inside and outside to observe cracking or any other evidence of failure. g) Failure in the test specimens shall be any crack or split on the inside or outside that was created by the impact and that can be seen by the naked eye. Lighting devices shall be used to assist in examining for cracks and splits in the walls of the pipe or fittings specimens. h) Failure of two or more of the specimens shall be deemed as failure of the product to meet the specified impact resistance requirement as given in Table IV. When only one specimen fails, a retestshall be made utilizing 6 additional speci- mens. To meet the specified impact resistance re- quirement,none of the 6 additional specimens shall fail in the retest. Sec. 7.

(b) Drop tube—The drop shall be made of cold -drawn seamless steel tubing with an inside diameter of 2.563 ± 0.003 inches; or of acryloni- trile -butadiene -styrene (ABS) or polyvinyl chlor- ide (PVC) plastic pipe, 21/2 inch nominal pipe size with a standard dimension ratio (SDR) of 21. Al- ternately, the tup may be dropped without a pro- tective tube provided other means are provided to protect the operator from the random rebound of the tup. It shall be sufficiently long (approximately 6 feet) to provide for a height of fall of at least 5 feet and shall be mounted so that the length- wise dimension is vertical as determined by a plumb bob. c) Tup hold and release—Means shall be pro- vided to hold the tup at steps of 1 -inch up to 5 feet above the pipe or fitting test specimen, as meas- ured from the bottom of the tup to the top of the specimen as mounted; to release the tup in a re- producible manner; to allow the tup to fall freely through the tube to strike the specimen; and to catch the tup on the first rebound. One type of device suitable for this test is shown in Figure 2. d) Specimen holder—The pipe specimen hold- er shall consist of a steel plate, 8 by 12 by 1 inch in which a V -groove to position the pipe specimen shall be cut. This V -groove shall be 1/8 -inch deep with an included angle of 120 degrees. The edges of the V -groove shall be rounded to 1/16 -inch. Fittings shall be laid on their side on a 0.50 -inch thick steel plate. Fittings that do not contact the steel plate directly under the point of impact shall be supported in this area by a steel shim or small steel plate. The specimen holders shall be mounted on a firm rigid base fastened to a heavy concrete slab. Means shall be provided to adjust the speci- men holders so that the specimens can be centered under the end of the drop tube. 6-11.2 Test specimens a) At least 6 pipe specimens shall be tested. 9 Specimen length shall be 6 ± 1/8 inches. Burrs on ends shall be removed. b) The thinnest wall of each fitting shall be determined. c) The first pipe test specimen shall be mounted with the thinnest wall section on top so that the tup strikes this area. The second speci- men shall be mounted so that the point of impact is 18 degrees from the thinnest wall, the third 36 degrees, etc. d) Symmetrical fittings shall be struck on the weld mark and 90 degrees from the weld mark; 3 specimens shall be impacted on the weld and 3 specimens 90 degrees from the weld. If the weld mark cannot be located, then the thinnest wall shall be used in place of the weld. Unsymmetrical fittings shall be tested by lay- ing the specimen, on its side and impacting the other side at the geometrical center. Three speci- mens shall be struck on one side and three on the other. e) The test specimen shall be placed under the end of the drop tube so that the side of the pipe or fitting shall be struck by the tup on the geometrical center of the side. The 12 -pound tup shall be dropped from the height necessary to pro- vide the impact energy requirement given in Table IV. Each test specimen shall be subjected to only one impact blow. f) The impacted specimens shall be carefully examined visually inside and outside to observe cracking or any other evidence of failure. g) Failure in the test specimens shall be any crack or split on the inside or outside that was created by the impact and that can be seen by the naked eye. Lighting devices shall be used to assist in examining for cracks and splits in the walls of the pipe or fittings specimens. h) Failure of two or more of the specimens shall be deemed as failure of the product to meet the specified impact resistance requirement as given in Table IV. When only one specimen fails, a retestshall be made utilizing 6 additional speci- mens. To meet the specified impact resistance re- quirement,none of the 6 additional specimens shall fail in the retest. Sec. 7. MARKING AND LABELING OF PIPE AND FITTINGS 7-1 Marking 7-1.1 .Pipe—The pipe shall be legibly marked. on two sides 180 degrees apart or spirally in white or yellow letters not less than 1/4, inch high and shall at least consist of the manufacturer's name or trademark, the nominal pipe size, the symbol ABS, and the symbol DWV, spaced at intervals of not more than 2 feet and shall include code control markings,* WPOA seal of approval" and may in- clude other markings required or permitted by law. 7-1.2 Fittings—All fittings shall be legibly marked on the body or hub on both sides. The marking shall consist, at least, of the manufac- turer's name and/or trademark, the symbol ABS- DWV, size of all openings and code control mark- ings", WPOA seal of approval" and may include other markings required or permitted by law. 7-2 Labeling—In order that purchasers may be assured that the ABS drain, waste, and vent pipe and fittings actually comply with all requirements of this Standard, it is recommended that manu- facturers include a statement in conjunction with their name and address on labels, invoices, sales literature, etc. to the effect that the specific pipe and/or fittings covered by the statement meet the requirements of this standard, referenced by number and title. Sec. 8. SOLVENT CEMENT REQUIREMENTS 8-1 General—Solvent cement for use with this pipe and these fittings shall be that recommended by manufacturers for use on ABS pipe and fittings and shall meet ASTM D -2235-63T Tentative Spec- ification for Solvent Cement for Acrylonitrile - Butadiene -Styrene (ABS) Plastic Pipe and Fit- tings. The solvent cement shall provide sufficient `open' time for making good joints and connec- tions, but joints should be completed immediately upon applying solvent cement. Should any delay develop in assembly, an additional coat of solvent cement should be applied immediately prior to J oining. CAUTION: If longer `open' time is required for some particular types of installation, special instructions and specifications should be re- quested from the cement manufacturer. Any solvent cement of this longer `open' time -type should be evaluated for possible deleterious ef- fects on the pipe and fittings. The use of slower drying solvent cement phould be avoided if at all possible. For additional assembly details see WPOA Standard IS 5-65. 8-2 Joint Tightness Requirement—Joints made with pipe and fit- tings shall not leak when tested with an internal pressure of 25 psi in accordance with the follow- ing test method. (This test is intended only for use to evaluate the ability of the cement to pro- duce tight joints between the pipe and the fittings, not for use as a simulated service test.) Test Method—Two pieces of pipe shall be joined together with a fitting by solvent cement and al- lowed to stand for 24 hours at room temperature. The specimen shall then be subjected to an inter- nal pressure of 25 psi, with water as the medium for 24 hours. Sec. 9. QUALITY PRODUCTION CONTROL 9-1 Manufacturers shall conduct daily tests (within their own plant facilities) on samples from each production run during each operating shift in accordance with Section 5 except for the sustained pressure test (6-5) and the low temperature (– 40°F) impact tests. 9-2 Test records shall be maintained for a pe- riod of not less than two (2) years. *Manufacturers shall maintain records for a minimum period of two (2) years of identification coding for each run or lot of material used in any production run of pipe or fittings. This identifying code marking shall reveal the day, month and year, quality control, source of raw material and batch number, and plant inspection control maintained to insure constant compliance with this stand- ard. Company records shall also include the shipments of finished products with reference to code control. * *NOTE— WPOA Seal of Approval is a copyrighted mark and may not be used unless products specified herein first have been submitted to and approved by the Re- search Committee of WPOA and permission granted therefor.

INTRODUCTION This installation standard shall apply to drain, waste and vent systems as governed by the Uni- form Plumbing Code. Material standard PS 17-65 published by Western Plumbing Officials Associa- tion shall form part of this Installation Standard. Sec. 2. PURPOSE This standard shall serve to supplement any ex- isting applicable standards and requirements of appropriate codes and laws regulating use of ABS pipe and fittings in drain, waste and vent systems and to provide the necessary requirements for in- stallation, use and inspection of ABS piping and fittings for this purpose. Sec. 3. IDENTIFICATION AND CHARACTER- ISTICS 3-1 ABS pipe is furnished in straight lengths. The pipe is black in color with white or yellow identi- fication markings on opposite sides or spirally around the barrel and duplicated every 24" in let- ters not less than 1/.t" high. The pipe wall is the same thickness as that of A.S.A. Schedule 40 (IPS) standard steel pipe. Fittings are furnished in either black or gray ABS with markings molded on both sides. Refer to tables in material standard PS 17-65 for dimensions and tolerances for pipe fitting sockets and laying lengths. 3-2 Pipe markings contain at least the following information: a) Company name or registered trademark of the manufacturer. b) Nominal pipe size. c) ABS-DWV. d) W.P.O.A. seal of approval. e) Any other markings required or permitted by law. f) Code control identification.* 3-3 Fittings are marked on both sides with at least the following information: a) Company name or registered trademark. b) ABS-DWV. c) Size of openings. d) W.P.O.A. seal of approval. e) Any other markings required or permitted by law. f) Code control markings.* Sec. 4. STORAGE Pipe and fittings shall not be stored in direct sunlight. Pipe shall be stored in such a manner as to prevent sagging or bending. Sec. 5. INSTALLATION 5-1 Location of markings 0 5-1.1 Pipe and fittings shall be so positioned that identifying markings shall be readily visible for inspection. 5-2 Solvent Cement 5-2.1 Solvent cement shall be as specified in • ASTM Standard D2235 -63T. The cement shall be packaged in one quart containers or smaller for field use. 5-2.2 Should cement thicken in container it may be thinned with Methyl Ethyl Ketone (MEK) or thinner supplied by the cement manufacturer. 5-3 Socket Fit 5-3.1 ABS fittings are manufactured to close tolerances. Close tolerances are required to insure satisfactory `interference' fit between pipe and fitting during the solvent cement joining. 5-3.2 Pipe or fitting shall not be used if inter- ference fit is not evident. (Pipe even a few thous- andths undersize and loose in the socket cannot be properly fused chemically. The allowable toler- ances assure a forced fit and when solvent is ap- plied will readily mate, thus assuring a chemical fusion equal in strength to pipe or fitting. Filling the void with cement in a loose fit will tend only to soften pipe and fitting and weaken the joint.) 5-3.3 The ideal fit between pipe and fittings before cement is applied is for the pipe to enter the socket easily for a distance of 1/4 to 3/4 of the socket depth. *An identifying marking which corresponds to company records of control and distribution of each production run. 1 J • 9 5-4 Joining Technique 5-4.1 Pipe shall be cut square; protect pipe and fittings from serrated holding devices and abra- sion. 5-4.2 Remove burrs and wipe off all dust, dirt and moisture from surfaces to be cemented. 5.4.3 Using an ordinary pure bristle paint brush of adequate size, or the brush supplied with the can of solvent cement, first apply a moderate even coating of cement in the fitting socket completely covering the pipe joining surfaces only. Heavy or excessive applications of cement will become an obstruction inside of the piping. Quickly apply cement to the outside of the pipe. Make sure that the coated distance on the pipe is equal to the depth of the fitting socket. 5-4.4 Assemble joint as quickly as possible be- fore cement dries. 5-4.5 Insert pipe into fitting socket turning the pipe slightly to insure even distribution of cement. Make sure that the pipe is inserted to the full depth of the socket. 5-4.6 Should the cement dry partially before joint is made up, reapply cement before assem- bling. 5-4.7 Allow 15 minutes for joint to develop good handling strength. 5-5. Threaded Joints 5-5.1 ABS-DWV pipe shall not be threaded. Use of adapter fittings for transition to threaded construction is necessary except in the case of cleanout plugs. The joint between the ABS pipe and transition fitting shall be of the -solvent ce- ment type. 5-5.2 Only approved thread tape or thread lu- bricant specifically intended for use with ABS may be used. Conventional pipe thread compounds, putty, linseed oil base products and unknown mix- tures shall be avoided. Under no circumstances shall methyl alcohol or petroleum products be em- ployed for testing ABS piping systems or for frost protection in traps. See paragraph 6 for anti- freeze protection. 5-5.3 Threads must not be over -tightened. Tighten no more than one turn past hand -tight using a strap wrench. 5-6 Alignment and Grade 5-6.1 All piping system components must be aligned properly without strain. Pipe must not be bent or pulled into position after being solvent welded. 5-6.2 Grade of horizontal pipe shall be as spec- ified for other materials in the Uniform Plumbing Code. 5-7 Supports and Spacing 5-7.1 Hangers shall not compress, distort, cut or abrade the piping. 5-7.2 Support all piping at intervals of not more than four (4) feet at ends of branches, and at change of direction or elevation. Vertical piping shall be maintained in straight alignment. Support trap arms in excess of three (3) feet in length as close as possible to the trap. Closet ring shall be securely fastened to floor with top surface one quarter (1/4) inch above finish floor. 5-7.3 Pipe exposed to damage by sharp metal surfaces shall be protected with grommets or sleeves of rubber or plastic. 5-8 Thermal Expansion 5-8.1 Allow for expansion and movement in all piping installations. Do not rigidly restrain piping at branches or changes of direction. In general buried piping or piping concealed in walls or floors does not present a problem. 5-8.2 Thermal expansion for installations ex- posed to extreme temperature changes may be de- termined from the following table. The linear ex- pansion shown is independent of the diameter of the pipe.

Length of run -60 Ft. From chart, read 2.010 inches linear expansion that must be provided for. 5-9 Trenching 5-9.1 Make trench bottoms smooth and regular in either undisturbed soil or a layer of compacted backfill so that no settlement will take place. Pipe must bear on this material throughout the entire length of its barrel. Maintain the proper grade as described in paragraph 5-6.2. 5-9.2 Backfill material should be free of large rocks which may cause impact damage when al- lowed to fall against the pipe. Cover exposed pipe with light colored paper or similar material until test and inspections have been completed. This procedure will prevent excessive expansion and contraction due to temperature changes and will enable the pipe temperature to more quickly reach equilibrium with surrounding soil temperature. • *NOTE — WPOA Seal of approval is a copyrighted mark and may not be used unless products specified herein first have been submitted to and approved by the Re- search Committee of WPOA and permission granted therefor. 5-10 Exposed Piping 5-10.1 Adequate support shall be provided where ABS piping is exposed to wind, snow and ice loading. 5-10.2 Plumbing vents and other pipe surfaces exposed to sunlight shall be protected by water base synthetic latex paints. Where surface tem- peratures exceed 165°F piping shall be protected by means of shielding or some type of lightweight insulation. Sec. 6. ANTI -FREEZE PROTECTION When necessary to protect traps and fixtures from freezing do not use alcohol. Use only ap- proved plastic pipe antifreeze packaged for this purpose or one of the following solutions: a) 60% by weight of glycerol in water mixed at 74° temperature. b) 22% by weight of magnesium chloride in water. Strong solutions of common table salt (so- dium chloride) may also be used. January 12, 1965 U 0,
