3.8.4 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 pat-a. 3.13.
3.9 ResIstance to Chemicals and Solvents
3.9.1 Test Requirement. The valve shall be attached to a sink fitted with a standard cresspiece outlet
3.9.2 Substances to Be Tested. Each test shall be carried out separately using a quantity of 4 pt (12 ft oz or 0.35 L) of one of the following solvents:
(a) solvent 1: liquid drain cleaner containing sulfu. nc acid
(b) solvent 2: mineral spirits
(c) solvent 3: kerosene
3.9.3 Test Method. The material shall be poured into the sink outlet. After one minute. pour 4 pt (64 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 accordance with para. 3.2 and meet the requirements of para. 3,2.3.
3.10 Drop
3.10.1 Test Method. The test 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 orientation (sideways) and release onto concrete. Observe the valve for any changes.
3.10.2 Performance Requirements. The valve shall show no signs of deformation or breakage that may affect its function.
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 20.000 cycles. A cycle comprises lOsec exposure to the solution, followed by 10 sec of draining.
3.11.3 Performance Requirements. AL the completion of the above test, the valve shall be tested in accordance with para. 3.2.
MARKING,IDENTIFICATION,AND INSTRUCTIONS4.1 Marking and ldentification
The valve shall be permanently and legibly markedwith the following:
(a) manufacturer’s name
(b) product name /brand name
(c) nominal size of inlet and outlet
(d) date of manufacture
(e) predominant material.
