ASME A112.18.8:2009 pdf free download.In-Line Sanitary Waste Valves for Plumbing Drainage Systems.
ASME A112.18.8 establishes minimum requirements for materials in the construction of sanitary waste valves (hereinafter referred to as “the valve”) for use as an alternate to tubular p-traps, and prescribes minimum test requirements for the performance of the valve, together with methods of marking and identification. This Standard does not define the requirements for products to be used in urinals or water closets. It is not intended that products meeting this Standard will be used in a urinal or water closet.
The provisions of this Standard are not intended to prevent the use of any alternate material or method of construction provided any such alternate meets the intent of this Standard.
1.2 Units of Measurement
Values are stated in US. Customary units and in the International System of Units (SI). The US. Customary units shall be considered as the standard.
In this Standard, gallons (U.S. liquid) per minute is abbreviated gpm and liters (metric liquid) per minute is abbreviated L/min.

3.5.2 Performance Requirements. The valve shall
show no evidence of leakage and demonstrate air tightness.
3.6 Thermal Cycling
3.6.1 Test Requirement. The valve shall complete the following thermal cycling test procedure for 5 cycles and allow 5 sec of draining time between cycles:
(a) 7.9 gpm (30 1/mm) of water at a temperature of 203°F ± 4°F (95°C ± 2°C) over a period of 15 mm at a constant flow rate
(b) 7.9 gpm (30 1/mm) of water at a temperature of 68°F ± 10°F (20°C ± 5°C) over a period of 10 mm at a constant flow rate
3.6.2 Performance Requirements. At the completion of the above test, the valve shall be tested in accordance with para. 3.2 and meet the requirements of para. 3.2.3.
3.7 Cyclic Fatigue
3.7.1 Test Requirement. The valve shall complete the following cyclic fatigue test procedure allowing 60 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 of 59°F ± 10°F (15°C ± 5°C), flow rate 7.9 gpm ± 0.1 gpm (30 L/min ± 0.5 L/min).
3.7.2 Performance Requirements. At the completion of the above test, the valve shall be tested in accordance with 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 attached to .i sink fitted with a standard crosspiece outlet.
3.8.2 Substances to Be Tested. Each test shall be carried 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 X ‘/4 in. X 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, each at 150°F (65.6°C)
