A test pressure greater than 550 kPa (80 psi) shall not be used.(d) The specimen shall be placed on a flat and level or plumb surface, with the outlet and trap clear.(e) The specimen shall discharge to atmosphere.Tests

19、 shall be conducted in the sequence specified in Table 5.7.1.2 Gravity flush tank water closetsAt each test pressure specified in Table 5 for gravity flush tank water closet tests, the water level in the tank and the fill time shall be adjusted in accordance with the manufacturers instructions and s

20、pecifications. Water closets that require higher minimum supply pressures shall be adjusted in accordance with the manufacturers instructions. In the absence of manufacturer instructions and specifications, the fill valve shall remain set as received from the manufacturer.Adjustments to the componen

21、ts inside the tank shall not be made once the water level and fill time adjustments have been made for the water consumption test pressure of 140 kPa (20 psi).All remaining tests shall be performed at a pressure of 140 kPa (20 psi) (or the higher minimum operating pressure specified by the manufactu

22、rer).The test methods and performance requirements specified in Clauses 7.13 and 7.14 shall apply to high-efficiency gravity tank toilets only.7.1.3 Flushometer tank, electro-hydraulic, or other pressurized flushing device water closetsAt each test pressure specified in Table 5 for flushometer tank,

26、 test laboratory conditions.7.1.5.1 Note: See Figure 11.The procedure for standardizing the water supply system for testing gravity flush tank close-coupled water closets, and flushometer tank one-piece and close-coupled water closets, shall be as follows:(a) Adjust pressure regulator 4 to provide a

27、 static pressure of 140 7 kPa (20 1 psi).(b) With stop valve 10 open, adjust valve 6 to establish a flow of 11.4 1 L/min (3.0 0.25 gpm) at 55 4 kPa (8 0.5 psi) flowing pressure measured at gauge 7.(c) Keep valve 8 fully open, except when it is used to shut off the flow completely.(d) Remove stop val

28、ve 10 and install the specimen.7.1.5.2 Note: See Figure 12.The procedure for standardizing the water supply system for testing flushometer valve water closets shall be as follows:(a) Set the static pressure at gauge 7 by adjusting pressure regulator 4 to(i) 240 kPa (35 psi) for flushometer valve wat

29、er closets; and(ii) 310 kPa (45 psi) for blowout bowls.19(Replaces p. 19, July 2013) The American Society of Mechanical EngineersASME A112.19.2-2013/CSA B45.1-13 2013 CSA GroupOctober 2013(b) Attach the flushometer valve, with matching supply stop in the fully open position, at the discharge end of

30、the water supply system and leave the flushometer valve discharge outlet open to the atmosphere.(c) Activate the flushometer valve and establish a peak flow rate, by adjusting valve 8, of(i) 95 4 L/min (25 1 gpm) for flushometer valve water closets; and(ii) 133 4 L/min (35 1 gpm) for blowout bowls.I

31、f the flushometer valve specified by the manufacturer is not capable of attaining the applicable minimum flow rate, adjust the flushometer to its fully open position.(d) Connect the flushometer valve to the test bowl.(e) Record the peak flowing pressure at gauge 10 and the peak flow rate through the

32、 flushometer valve while it is attached to the bowl. While conducting water consumption testing at 350 and 550 kPa (50 and 80 psi), maintain the peak flow rate at 4 L/min ( 1 gpm) by adjusting valve 9 as necessary.7.1.6 Test mediumIf a test requires a test medium, the medium shall be placed in the w

33、ater closet bowl and the flushing device activated as specified in the applicable test procedure clause of this Standard. The specimen shall discharge into a receiving vessel or drainage system. The medium remaining in the bowl, if any, and that discharged into the receiving vessel or drainage syste

34、m shall be observed. If necessary, the specimen shall be flushed again to remove the remaining medium from the bowl or trap before each test run.7.1.7 ReportsTest results shall be evaluated and reported in accordance with the procedures specified for each test. Suggested formats for reporting test r

35、esults are shown in Figures A.1 to A.6. Alternative formats for accurately reporting test data shall also be acceptable.7.2 Trap seal depth determination testNote: See Figure 13.7.2.1 ApparatusFigure 13 shows an acceptable apparatus for determining trap seal depth. Another apparatus, e.g., a steel t

36、ape measure or a steel rule with a perpendicular horizontal element secured to one end, may also be used.7.2.2 ProcedureThe trap seal depth determination test shall be conducted as follows:(a) Lower the probe until the horizontal element is resting against the trap dip.(b) Record the corresponding s

37、cale value as h1.(c) Disengage the horizontal element from the probe.(d) Elevate the probe completely out of the water.(e) Confirm that the specimen is at full trap seal depth by slowly pouring water into the well until a slight overflow is detected dripping from the bowl outlet.(f) When the drippin

38、g ceases, adjust the probe so that its point is exactly at the water surface.(g) Record the corresponding scale value as h2.(h) Calculate the full trap seal depth, Hf, by subtracting h1from h2(Hf= h2 h1).7.2.3 ReportThe full trap seal depth, Hf, shall be reported.7.2.4 PerformanceThe full trap seal

39、depth, Hf, shall be at least 51 mm (2.0 in).(Replaces p. 20, July 2013)20BADC The American Society of Mechanical Engineers 2013 CSA Group Ceramic plumbinig fixturesOctober 2013Table 4Minimum dimensions for urinals, mm (in)(See Clause 4.7.2.)Type of urinalABC DInterior depth ProjectionInteriorwidthIn

No adjustments shall be allowed between tests employing like pressures.(3) For water closets with alternative materials in the trap

46、, the auger test of Clause 6.10 shall be conducted before the tests in this Table.(4) Where a higher minimum operating pressure is specified for a fixture by a manufacturer, the specified pressure shall be substituted for the minimum test pressure specified in this Table. The manufacturers specified

47、 operating pressure shall be indicated in its product literature and on its product packaging.(5) Gravity flush tank and flushometer tank water closet types include siphonic, pressure-assist (other than flushometer valve models), and washout bowl.(6) The manufacturers safe-operating pressure recomme
