ASME A112.19.12:2000 pdf download.WALL MOUNTED AND PEDESTAL MOUNTED, DJUSTABLE AND PIOTING LAVATORY ANDSINK CARRIER SYSTEMS.
3.1.2 Vertical Adjustment
3.1.2.1 Test Method. lhe assembled systemshall be operated throughout its full range of verticaladjustment and the travel shall be measured.
3.1.2.2 Performance Requirement. The car-rier shall provide a vertical adjustment of not morcthan 12 in. (300 mm).
3.2 Flexible Waste System3.2.1 Trap Seal
3.2.1.1 Test Method.The wall mounted or ped-estal mounted adjustable lavatory or sink carrier systemand fexible waste system shali be instaiied in accord-ance with the manufacturer's instructions.The lavatoryshal be positioned at its minimum adjustable heightand the depth of seal shaill be measured. The lavatoryor sink shaii then be raisedi io itsmaximum hcightand the depth of seal shali again be mcasurcd. Aftermcasuring thue leighi difference causcd by verticaladjustment，thc mcasuremcnt of the trap seal of theexlremes in the latcral fixture movement shall also bemeasured.
3.2.1.2 Performance Requirement. The trapseal depth shall not be less than 2 in. (50 mm) andnot greater than 9in. ([230 mm) at any position.3.2.2 Hydrostatic Pressure Test
3.2.2.1 Test Method. The outlet of the drainshall be plugged at the stub out connection.The flexiblewaste system shall he slowly flled with water. allowingall air to escape.'The inlet of the flexible wasie systemshall then be capped. allowing for a means toappiya hydrostatic pressure of 25 psig (170 kPa gauge),which shall be maintained for a period of o0min.
3.2.2.2 Performance Requirements. Thefilled assembly shall not leak during the test time period.
3.2.3 Flow Test
3.2.3.1 Test Method. The lavatory shall bcpositioned at its minimum adjustable hcight. A watersuppiy shaii bc adjusted to supply water through thelavatory faucet at a rate of 7.l gpm (27 L/min). Elapsedtime shall be measurcd from the onset of flow intothe lavatory.
