ASME A112.19.12 pdf download Wall Mounted, Pedestal Mounted, Adjustable, Elevating, Tilting, and Pivoting Lavatory, Sink, and Shampoo Bowl Carrier Systems and Drain Waste Systems
22.214.171.124 Test Method. The assembled system shall be operated throughout its full range of vertical adjust- ment and the travel shall be measured.
126.96.36.199 Performance Requirement. The carrier shall provide a vertical adjustment of not less than 2 in. (51 mm) and not more than 30 in. (762 mm), and a pivotal or tilted adjustment of not less than 10 deg and not more than 20 deg.
3.2 Flexible Waste System or Telescoping Tailpiece Waste System 3.2.1 Trap Seal
188.8.131.52 Test Method. The wall mounted or pedes- tal mounted adjustable or elevating lavatory, shampoo bowl, or sink carrier system and flexible waste system or a telescoping tailpiece waste system shall be installed in accordance with the manufacturer’s instructions. The lavatory, sink, or shampoo bowl shall be positioned at its lowest position. Fill the trap with water until water flows from the outlet of the flexible waste system or telescoping tailpiece waste system. Measure the depth of the trap seal. After measuring the height difference caused by vertical adjustment, the measurement of the trap seal ofthe extremes in the lateral, pivoting, or tilting fixture movement shall also be measured. The lavatory, sink, or shampoo bowl shall then be raised to its highest position and the depth of seal shall again be measured.
184.108.40.206 Performance Requirement. The trap seal depth for the flexible waste system or the telescoping tailpiece waste system shall be not less than2 in. (51 mm) at any position. 3.3 Aging Test for the Flexible Waste System 3.3.1 Test Method. Flexible drain hose shall be aged at atmospheric pressure and elevated temperature. Age a specimen ata temperature of140°F ± 3.6°F (60°C ± 2°C) for 166 hr.
3.3.2 PerformanceRequirement. Afterthe exposure, examine the test specimen for surface cracks under 2؋ magnification. Presence of any cracking shall be cause for failure. In addition, perform the hydrostatic pressure test as described in ASME A112.18.2/CSA B125.2. The flexible waste system shall not leak during the test time period.
3.4 Cycle Test
3.4.1 Flexible Waste System Pivot and Tilt Cycle Test. The assembled joints in the flexible waste hose 3 system shall be cycle tested. Install the flexible hose to simulate actual installation. Fix the rigid outlet fitting to which the hose is joined at a point 3 in. ± 1 ⁄ 8 in. (76.2 mm ± 3.2 mm) from the inlet end. Attach the flexible hose to the cycling fixture at a point 12 in. ± 1 ⁄ 8 in. (304.8 mm ± 3.2 mm) upstream ofthe rigid fitting attach- ment. One cycle shall consist of moving the flexible hose back and forth one time through 20 deg of pivoting or tilting. The 20 deg shall begin at 10 deg from the center- line of the outlet fitting and end 10 deg at the opposite side of the centerline. Cycle the hose 20,000 times at 70°F ± 5°F (21.1°C ± 2.8°C) at a minimum of six cycles per minute. At the conclusion of the 20,000 cycles, per- form the pressure test as described in para. 2.4.4. The joint(s) shall not leak.
3.4.2 Flexible Waste System and Telescoping Tailpiece Waste System Vertical Cycle Test. Both assem- bled waste system assemblies shall be cycle tested. Install each respective waste system to simulate actual installation. Fix the bottom outlet fitting to which the waste system is joined at a point 7 in. ± 1 ⁄ 8 in. (177.8 mm ± 3.2 mm) from the floor. Attach the top end of the waste system to the cycling fixture at a point 19 in. ± 1 ⁄ 8 in. (482.6 mm ± 3.2 mm) above the rigid fitting attachment. One cycle shall consist of moving the waste system up and down one time through its maximum of vertical travel. The vertical travel shall begin at the fully closed position and extend towards the fully extended position. Cycle the waste system 20,000 times at70°F ± 5°F (21.1°C ± 2.8°C) at a minimum of six cycles per minute. At the conclusion of the 20,000 cycles, perform the pressure test as described in para. 2.4.4. The joint(s) shall not leak.
