2.4 Flexible Waste System and Telescoping Tailpiece Waste System The trap seal provided by the flexible waste system shall be a minimum of 2 in. (51 mm) in depth, when evaluated in accordance with para. 3.2. Materials used in the construction of the flexible waste system shall be metallic, plastic, or elastomeric that comply with the requirements 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 minimum outside diameterof1 1 ⁄ 2 in. (39 mm) forsinkand shampoo bowls and 1 1 ⁄ 4 in. (32 mm) minimum for lavatory tail- pieces. Thestandpipe maybe constructed ineithersingle or multiple stage models for different applications. All moving components shall be designed and constructed to 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 Linkage Material. Linkage materials that contain stainless steel cables shall comply with Fed Spec RR-W-410. Cable eyes shall be constructed from 300 Series stainless steel and not to break under a load of 480 lb (217.7 kg), or comply with 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).
3.1.2.2 Test Method. The assembled system shall be operated throughout its full range of vertical adjust- ment and the travel shall be measured.
3.1.2.3 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 3.2.1.1 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.ASME A112.19.12 pdf download.ASME A112.19.12-2000 pdf free download
