AS 1172.1 2005 2 PREFACE This Standard was prepared by the Standards Australia Committee on Sanitary Plumbing Fittings to supersede AS 1172.1 1993, Water closets of 6/3 L capacity, Part 1: Pans on publication. This Standard was prepared by the Australian members of the Joint Standards Australia/Standards New Zealand Committee WS-003. After consultation with stakeholders in both countries, Standards Australia and Standards New Zealand decided to develop this Standard as an Australian Standard rather than an Australian/New Zealand Standard. The objective of this Standard is to provide manufacturers, importers, suppliers and users with requirements for pans for water closets. Major alterations to the 1993 edition include (a) introduction of the reduced flush liquid contaminants test (Appendix H); (b) minor revisions of a number of other tests (without changing the substance of the tests); and (c) editorial revision of the whole document including revision of the style of the Standard and the re-numbering of Clauses. This Standard covers water closet pans of all types suitable for reduced-flush matched performance sets (for example 6/3 L) and other nominated combinations intended for use with flushing cisterns complying with AS 1172.2. This Standard meets the recommended policy of the Australian Water Resources Council (AWRC) for dual-flush and reduced-flush volumes and its definition for proven equivalent and does not preclude the development of alternative technologies and discharge volumes, which may be acceptable to the Water Authorities.

(d) Drop four test pieces into the water area of the bowl of the pan from a point level with the top of the rim using directional device according to Figure C8. (e) Full-flush test (recommended) Activate the full-flush mechanism of the cistern or flush valve to flush the pan and observe the discharge to establish when the last of the four test pieces is discharged from the outlet spigot of the pan. The trailing volume water shall be determined using a suitable measuring device (see Figure C7). (f) Dual-flush test In the case of a dual-flush cistern of a matched performance set, if the effective residual water in the cistern, after the less than full-flush mechanism has been actuated, exceeds 2.5 L and the test pieces were discharged, then the trailing water volume test is deemed to have passed the test criteria as set out in this Appendix, i.e. the full-flush discharge volume of the cistern less the reduced flush discharge volume equals an active retention volume in excess of 2.5 L. If the volume retained in the cistern is less than 2.5 L, the dual-flush cistern matched performance set must be tested in accordance with Paragraph C5 (e), Full-flush test. (g) Repeat the test nine times (total of ten tests) and record the results. (h) If the pan does not meet the requirements of Clause 3.3 for ten tests, it may be tested a further ten times (giving a total of twenty consecutive tests). (i) Record the results and record if the requirements of Clause 3.3 are complied with. C6 TEST REPORT The following shall be reported: (a) Manufacturer, model type and nominal flush capacity of the pan. (b) Manufacturer, model, nominal flush volume and type of cistern or flush valve.
