2.2 Fixture Mounting System
The wall mounted or pedestal mounted adjustmentmechanism shall provide the necessary means for
mounting the lavatory, sink, or shampoo bowl over themanufacturer’s intended range of travel, with an adjust-
able mechanism to position the fixture either vertically,laterally,or vertically and laterally, or allow the fixtureto pivot or tilt up and down.
2.3 Sink,Lavatory, or Shampoo Bowl Fixtures and
Flexible Water Supply Connectors
The sink, lavatory, or shampoo bowl fixtures and flexi-ble water supply connectors shall comply with the appli-cable product standard(s) regarding materials,manufacture, and installation. These include thefollowing (also listed in para.1.3):
(a) ASME A112.18.2/CSA B125.2(b)ASME A112.18.6/CSA B125.6(c)ASME A112.19.1/CSA B45.2(d)ASME A112.19.2/CSA B45.1(e) ASME A112.19.3/CSA B45.4(fyCSA B45.5/IAPMO Z124
2.4Flexible Waste System and Telescoping Tailpiece
Waste System
The trap seal provided by the flexible waste systemshall be a minimum of 2 in.(51 mm) in depth, when
evaluated in accordance with para. 3.2.Materials sedin the construction of the flexible waste system shall be
metallic,plastic, or elastomeric that comply with therequirements of para. 3.2 and ASME A112.18.2/
CSA B125.2.
2.4.1 Telescoping Tailpiece Construction.The tele-
scoping tailpiece waste system shall have a minimumoutside diameter of 11/in.(39 mm) for sink and shampoobowls and 17/4 in.(32 mm) minimum for lavatory tail-
pieces.The standpipe may be constructed in eithersingleor multiple stage models for different applications.Allmoving components shall be designed and constructedto seal with a double O-ring at each junction.The stand-pipe must always be installed in a vertical position.
2.4.2 Telescoping Tailpiece Waste System LinkageMaterial. Linkage materials that contain stainless steelcables shall comply with Fed Spec RR-W-410.Cable eyesshall be constructed from 3o0Series stainless steel andnot to break under a load of 480 1b (217.7 kg), or complywith Mil Spec 20668.
2.4.3 Trap Seal of Flexible Hoses. PVC wastes that contain a flexible waste hose shall be factory solvent welded to the trap or trap adapter using PVC solvent cement complying with ASTM D2564. The flexible hose shall be supported in such a manner that it is prevented from bending to form a second trap.
2.4.4 Pressure and Leakage Tests. The flexible waste system or a telescoping tailpiece waste system shall comply with the pressure and leakage require- ments of ASME A112.18.2/CSA B125.2.
2.4.5 Flow Test. The flexible waste system or a tele- scoping tailpiece waste system shall comply with the flow rate requirements of ASME A112.18.2/CSA B125.2.
2.5 Flexible Water Supply Connectors Flexible water supply connectors shall comply with ASME A112.18.6/CSA B125.6. 3 TESTING 3.1 Adjustable, Elevating, Tilting, and Pivoting Lavatory, Sink, and Shampoo Bowl Carrier Systems
3.1.1 Load Testing
3.1.1.1 Test Method for Mounting System. The mounting system shall be installed in accordance with the manufacturer’s instructions. A load of 250 lb (113.4 kg) shall be applied on the top of the lavatory, sink, or shampoo bowl fixture rim for a period of15 min, in both its highest and lowest positions. When lateral adjustments are provided, the test shall be conducted to apply the load of 250 lb (113.4 kg) to the carrier. After application of the required load, the assembly shall be inspected for damage. The device shall be operated through its full range of travel. 3.1.1.2 Performance Requirement. The assembly shall demonstrate no sign of damage during and after the application of the load. When the device is operated through its full range of travel, it shall function as it did prior to the load test.
3.1.2 Vertical, Pivotal, and Tilt Adjustment 3.1.2.1 Adjustment. The mounted adjustment mechanism shall provide adjustment for use as specified by the product manufacturer. For an adjustable position or elevating sink, lavatory, or shampoo bowl with speci- fied pivotal and tilt adjustment, the mechanism shall provide a pivot or tilt adjustment of not less than 10 deg and not more than 20 deg. For an adjustable position or elevating sink, lavatory, or shampoo bowl with specified vertical adjustment, the mechanism shall provide verti- cal adjustment not less than 2 in. (51 mm) and not more than 30 in. (762 mm).
