ASME A112.18.8:2009 pdf download.ln-Line Sanitary Waste Valves for Plumbing Drainage Systems.

3.8.4 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.

3.9 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 4% pt (12 f ozor

0.35 L) of one of the following solvents:

(a) solvent 1: liquid drain cleaner containing sulfu-ric acid

(b) solvent 2: mineral spiritsic) 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 for 24 hr.

3.9.4 Performance Requirements. At the completionof the abowe 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 walve 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 20,000cycles. 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.
