9、 (This Foreword is not part of ASME A112.19.6-1995.) This Standard was developed from the ASME/ANSI Al 12.19.2-1982 Vitreous China Plumbing Fixtures standards in an effort to identify key operational performance tests for water closets and urinals. It includes a revised series of tests for waste rem

10、oval and water consumption of water closets and urinals. Laboratory tests in the body of the text are mandatory for compliance with this Standard. Except as specified, additional laboratory tests in the Appendix are optional tests which may be used to evaluate bowl performance characteristics not co

11、vered in the required tests. The Drainline Transport Characterization Procedure was added to the Standard in response to concerns about the impact of low consumption water closets on plumbing drainlines. Since existing research does not correlate laboratory results with actual field results, the 40

12、ft average carry may need to be adjusted as experience with low consumption water closets is developed. Efforts are ongoing to develop additional tests for fouling deposition and for bowl classification by use. Future editions will reflect these changes. Due to extensive tech- nological growth in lo

13、w consumption product designs, it is the intent to revise this Standard on frequency rather than the required five year cycle. Section 9 of this document was added to reflect the basic parameters for testing products other than hydraulic-only designs. Although originally suggested as an Appendix to

14、the Standard, it was moved to the body of the Standard to be consistent with ASME policies for standards development. This Standard has been approved by the ASME Committee A112, Standardization of Plumbing Materials and Equipment, Panel 19 on Plumbing Fixtures and by the American Society of Mechanic

15、al Engineers. On April 6, 1995, the American National Standards Institute adopted this proposal as an American National Standard, and designated it as The Working Group is continuing in its efforts to improve this Standard. Amendments in the forthcoming edition will include new tests and product cla

16、ssifications for water closet bowls.

(a) Test Method (2) Apparatus. A test apparatus shall be assem- bled. A suggested method is shown in Fig. A-1 . The

23、receiving vessel shall be permitted to be tested with either a vessel which is calibrated in volume incre- ments not exceeding 0.1 gal. (0.4 L) or with the use of a load cell with readout in increments not exceeding 0.1 gal. (0.4 L). (2) Procedure. The static pressure shall be ob- served, then the f

When the main flush is completed, as indicated by cessation of the trailing flow which occurs at the end of the principle discharge, the v

26、7.1.6.2 Trap Seal Depth Determination (I) Apparatus. Fig. A-4 depicts a suggested ap- paratus for determining trap seal depth. (2) Procedure. The probe shall be lowered until horizontal element is resting against the bottom of the trap dip. The corresponding scale value, hl shall be observed. Then t

27、he horizontal element shall be disengaged from the trap dip. The probe point shall be elevated to approximately the water surface cor- responding to a full trap seal. Water shall be poured slowly in well until slight overfill is indicated by drip- ping from the bowl outlet. When dripping ceases, the

Calculate full trap seal depth by (a) Test Method Hj= hi- hl For bowls with jet opening above trap dip, measure residual trap seal depth by the amount of back pressure required to

34、he values of hi, hZ, and Hfdescribed above shall be reported in Table A-6. )Performance Requirement. The trap seal shall assure protection against suction and back pressure in the sanitary drainage system and against destruc- tion from evaporation during normal periods of non- use. A full seal depth

35、 not less than that specified in ASME A112.19.2M shall be deemed adequate to sat- isfy this requirement. (a) Test Method 7.1.6.3 Trap Seal Restoration (1) Procedure. When making the test specified in paras. 7.1.3.1, 7.1.3.2, and 7.1.6.1, observations for trap seal restoration shall be made after flu

36、shing. The appearance of overflow in the drain following the main flush shall be a sufficient indication of ad- equate trap seal restoration. If no overflow is ob- served, residual trap seal depth shall be measured by the procedure described in para. 7.1.6.2(a), omitting the addition of water to the

37、 well. The residual trap seal depth shall be calculated by H,= h3 - hl (see Fig. A-4). (2) Report. If afterflow is observed following each initial flush in the specified tests shall be re- ported. Measured residual trap seal depth shall be reported if no afterflow is observed. See Table A-6 for an a

38、cceptable format. (b) Performance Requirement. Residual trap seal (average of each multiple-run test set) shall be not less than the values given in ASME A112.19.2M as applicable. Procedure 7.1.7 Drainline Transport Characterization 7.1.7.1 Test Method (a) Apparatus (see Fig. A-7). An assembly shall

39、 be made using a minimum of 60 ft of 4 in. I.D. clear, rigid plastic or glass pipe connected directly to a 4 in. plastic l/4 bend, in accordance with ASTM D 331 1, or an 1.0. Schott (Kimm) glass 4 in. bend center elbow using hubless coupling or solvent cement as appli- cable. The elbow shall be conn

40、ected directly to the loor flange. The pipe shall run backward from the water closet and shall be adequately supported to provide a straight run having a 2% slope. For back outlet water closets, the drain shall be extended up from the floor levei using fittings complying with ASME A112.6.1 or using

41、4 in. plastic DWV piping and a sanitary tee so that the water closet outlet is at the manufacturers recommended height above the floor. (b) Procedure and Setup (I) Water supply and general conditions shall follow the recommendations described in para. 7.1.2 unless otherwise specified. (2) Procedure.

42、 Using the 100 polypropylene balls described in para. 7.1.3.1 place the balls in the bowl.

43、i GENERAL NOTES (a) This Table shows a sample calculation using hypothetical data. (b) An optional reporting table, which is subdivided in smaller increments, is found in Table A-7. Flush the bowl observing the distance of travel of each exiting ball. Remove all test media from the fixture and the p

44、ipe before beginning the next cycle. (c) Data, Reporting, and Calculation. To arrive at an overall measure of performance, the location of the balls after flushing shall be recorded in one of eight categories which represent various distances of travel down the drainline. These categories shall in-

45、clude those balls that remain in the bowl or trapway, those.that exited the 60 ft length of pipe, and one category for each 10 ft increment of pipe (0-10 ft, 10-20 ft, etc.). After the initial flush, the number of balls in each of the categories described above shall be counted and recorded. Then th

46、e procedure in para. 7.1.8. i) shall be repeated three times, recording the same data from each initial flush, To calculate the weighted carry distance, first the data in the same categories shall be added together for all three runs to get the total number of balls in each category. Then the total

47、number of balls in each category shall be multiplied by the average distance traveled as indicated below. Any balls remaining in the bowl or trap shall be considered to have traveled zero distance. Balls in a 10 foot segment of pipe shall be considered to have traveled the average distance of that 1

48、0 ft segment of pipe from the trapway. (Example: balls in the 10-20 ft segment are assumed to have traveled 15 ft.) Any 6 balls that exit from the 60 ft length of pipe shall be considered to have traveled 60 ft. The average carry distance shall be the weighted carry distances divided by the total nu

49、mber of balls (3 runs x 100 balls = 300 balls total). 7.1.7.2 Performance Requirement. The average carry distance (total carry of all balls divided by the total number of balls) shall be 40 ft or greater. 7.1.8 Water Rise Test 7.1.8.1 Test Method (u) Apparatus. A 0.25 in. diameter vertically po- sitioned rod shall be held in a mounting bracket which is supported on the rim. The bottom end of the rod shall be at an elevation 3 in. below the flood level of the rim. (b) Procedure. The rod shall be located over the highest
