ASME A112.19.12-2014 pdf download.Wall Mounted,Pedestal Mounted,Adjustable, Elevating,Tilting, and Pivoting Lavatory, Sink, and Shampoo Bowl Carrier Systems and Drain Waste Systems.
This Standard establishes physical requirements and tests addressing structural strength; adjustments; materials; drain line hydraulics; and mechanical, material, testing, marking, and documentation requirements for wall mounted and pedestal mounted, adjustable, elevating, tilting, and pivoting lavatory, sink, and shampoo bowl carrier systems and drain waste systems intended to facilitate use by individuals who are physically challenged.
The use of alternate materials or methods are permitted, provided the proposed material and method complies with the performance requirements and intent of this Standard.
1.2 Units of Measurement
Values are stated in U.S. Customary units and the International System of Units (SI). The U.S. Customary units shall be considered as the standard.
In this Standard, gallons (U.S. liquid) per minute is abbreviated as gpm.

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 of 15 mm, 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 specified 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 vertical adjustment not less than 2 in. (51 mm) and not more than 30 in. (762 mm).
3.4.2 Flexible Waste System and Telescoping Tailpiece Waste System Vertical Cycle Test. Both assembled 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. ± 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. ± 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 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, perform the pressure test as described in para. 2.4.4. The joint(s) shall not leak.
