ASME A112.18.8:2009 pdf download In-Line Sanitary Waste Valves for Plumbing Drainage Systems
3.5.1 Test Method. The valve must be tested inaccordance with the hydrostatic pressure test in ASTMF 409 using an internal pressure of 25 psi (172 kPa) for1 hr.
3.5.2 Performance Requirements.The valve shallshow no evidence of leakage and demonstrate airtightness.
3.6 Thermal Cycling
3.6.1 Test Requirement.The valve shall completethe following thermal cycling test procedure for 5 cyclesand allow 5 sec of draining time between cycles:
(a) 7.9 gpm (30 L/ min) of water at a temperature of203F ±4F (95c ± 2C) over a period of 15 min at aconstant flow rate
(b) 7.9 gpm (30 L/ min) of water at a temperature of68°F ±10°F(20°C ± 5C) over a period of i0 min at aconstant flow rate
3.6.2 Performance Requirements. At the completionof the above test, the valve shall be tested in accordancewith para.3.2 and meet the requirements of para.3.2.3.3.7 Cyclic Fatigue
3.7.1 Test Requirement.The valve shall completethe following cyclic fatigue test procedure allowing60 sec for draining between cycles: 1,500 cycles of 60 sec± 2 sec duration, at a temperature of 200°F ±4°F(93°C ± 2°C followed by 60 sec at a temperature of59°F± 10°F(15C± 5c), flow rate 7.9 gpm ±0.1 gpm(30 L/min ±0.5 L/ min).
3.7.2 Performance Requirements. At the completionof the above test, the valve shall be tested in accordancewith para.3.2 and meet the requirements of para. 3.2.3.3.8 Resistance to Household Substances
3.8.1 Test Apparatus.The valve shall be attachedto a sink fitted with a standard crosspiece outlet.
3.8.2Substances to Be Tested. Each test shall becarried out separately using a quantity of 1.5 oz (43 g)or 1.5 fl oz (44 mL) of one of the following materials:(a) material 1: food – uncooked long-grain rice(b) material 2: food – diced vegetable of size !/4 in.x %/4 in. x 1/4 in. (6 mm x 6 mm x 6 mm)
(c) material 3: cleaners — liquid soaps(d) material 4: solids — kiln-dried sand
(e) material 5: lard -95% water,5% melted lard, eachat 150°F(65.6°C)
3.8.3 Test Method.The material shall be placed onor around the sink outlet. Four pints (64 fl oz or 1.9 L)of water will then be poured onto the item to flush thematerial from the sink. For Materials 1 through 4, coldwater shall be used; for Material 5, warm water at 150°F (65.6C) shall be used.The system will then be left for24 hr.
3.8.4Performance Requirements.At the completionof the above test, the valve shall be tested in accordancewith para.3.2 and meet the requirements of para.3.2.3.
3.9 Resistance to Chemicals and Solvents
3.9.1 Test Requirement.The valve shall be attachedto a sink fitted with a standard crosspiece outlet.
3.9.2 Substances to Be Tested. Each test shall becarried out separately using a quantity of 3/4 pt (12 fl ozor 0.35 L) of one of the following solvents:
(a) solvent 1: liquid drain cleaner containing sulfu-ric acid
(bsolvent 2: mineral spirits(c) solvent 3: kerosene
3.9.3 Test Method.The material shall be pouredinto the sink outlet.After one minute, pour 4 pt(64 fl ozor 1.9 L) of cold water into the sink outlet to flush thesolvent from the sink. The system will then be left for24 hr.
3.9.4 Performance Requirements.At the completionof the above test, the valve shall be tested in accordancewith para.3.2 and meet the requirements of para.3.2.3.
3.10 Drop
3.10.1 Test Method.The test shall be conductedover a clean concrete surface.Hold the valve with thelowest point upside down,3 ft (0.91 m) above the surfaceand release the valve. Pick up the valve and changeorientation (top uppermost) and release onto concreteagain. Pick up the valve one final time and change orien-tation (sideways) and release onto concrete.Observe thevalve for any changes.
3.10.2 Performance Requirements.The valve shallshow no signs of deformation or breakage that mayaffect its function.
3.11 Life cycle
3.11.1 Test Requirement.Resistance of the valve tocyclic fatigue under ambient conditions shall be testedusing the apparatus shown in Fig.4.
3.11.2 Test Method. The valve under test shallundergo 20,000 cycles.A cycle comprises 10 sec exposureto the solution, followed by 10 sec of draining-
3.11.3 Performance Requirements.At the comple-tion of the above test, the valve shall be tested in accor-dance with para. 3.2.
