3.1.2 VerticalAdjustment
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 acijustable lavatory or sink carrier systemand fexible waste system shali be instaiied in accord-ance with the manufacturer’s instructions.The lavatoryshall be positioned at its minimum adjuslable leightand the depth of seal shall be measured. The lavatoryor sink shaii then be raiseci io its maximum heightand the depth of seal shali again be mcasurcd. Aftcrmeasuring tve leight diffcrence causcd by vertica!adjustment，thc mcasuremcnt of the trup 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 9 in. (230 mm) at any position.3.2.2 Hydrostatic Pressure Test
3.2.2.1Test 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 waste systemshall then be capped. allowing for a means to appiya hydrostatic pressure of 25 psig (1 70 kPa gauge).which shall be maintained for a periodl of 60min.
3.2.2.2 Performance Requirements. Thefilled assembly shall not leak during the test timeperiod.
3.2.3 Flow Test
3.2.3.1 Test Method. The lavatory shall bcpositioned at its minimum adjustable hcight. A watersuppiy siaii be adjusied to supply watcr through thelavatory faucet at a rate of 7.l gpm (27 Lmin). Elapsedtime shall be measurcd from the onset of flow intothe lavatory.
