ASME A112.18.8:2009 pdf download.ln-Line Sanitary Waste Valves for Plumbing Drainage Systems.
3.8.4 Performancr Requirements. At the completion of the above test, the valve shall be tested in accordance with pars. 3.2 and nwet 11w requirements of pars. 3.23.
3.9 ResIstance to Chemicals and Solvents
3.9.1 Test Requirement. The valve shall be ,tttshed to a sink fitted with a standard crosspiece outlet
3.9.2 Substances to Be Tested. Each test shall be carried out separately using a quantity of Pt (12 fl o or 0.35 L) of one of the following solvents:
(a) solvent 1: liquid drain cleaner containing sulfunc acid
(b) solvent 2: mineral spirits
(C) solvent 3: keresenc
3.9.3 Test Method. The material shall be poured into 11w sink outlet. After one minute. pour 4 p1(64 II oz or 1.9 1) of cold water into the sink outlet to flush the solvent from the sink. The system will then be left for 24 hr.
3.9.4 Performance Requirements. At the completion of the above test, the valve shall be tested in accordarwe with para. 32 and meet the requirements of pars. 3.23.
3.10 Drop
3.10.1 Test Method. The tcst shall be conducted over a clean concrete surface. Hold the valve with the lowest point upside down. 3 ft (0.91 m) above the surface and release the valve. Pick up the valve and change orientation (top uppermost) and release onto concrete again Pick up the valve one final time and change onentation (sideways) and release onto concrete (Yoserve the valve for any changes.
3.10.2 Performance Requirements. The valve shall show no signs of deformation or breakage that may affect its fundion.
3.11 LIfe Cycle
3.11.1 Test Requirement. Resistance of the valve to cyclic fatigue under ambient conditions shall be tested using the apparatus shown in Fig. 4.
3.11.2 Test Method. The valve under test shall undergo 2i.),LA*) cycles. A cycle comprises 10 sec exposure to the solution. followed by 10 sec of draining.
3.11.3 Performance Requirements. At the completion of the above test, the valve shall be tested in accordance with pars. 3.2.
