For Committee WS-032 use onlyPREFACEThis Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee WS-032, Water Efficient Products, to supersede AS/NZS 3662:1996.The Plumbing Code of Australia r

14、equires that water efficient products be certified to WaterMark Level 2.The objective of this Standard is to specify the requirements for showers for bathing purposes. Shower types include(a) showerheads fastened to fixed arms;(b) showerheads fastened to pivotal arms;(c) hand-held showers connected

15、to flexible hoses, and(i) supported by a fixed wall handset holder;(ii) attached to a slide rail; or(iii) mounted on a holder attached to a bath/shower mixer.Where showers are sold together with other components (e.g., a fixed or pivot arm, a flexible hose with or without a flow controller), which c

16、ould affect the performance of the shower, such components will need to be attached to the shower for testing. Where showers are sold together with components that would not affect their performance (e.g., tap top assemblies, or other components), such additional components need not be attached to t

17、he shower for testing.This revision includes(a) an extended definition of a shower to include relevant components;(b) amended test procedures;(c) requirements for shower hoses; and(d) a method for determining the effective diameter of non-circular-shaped showerheads. The term normative has been used

18、 in this Standard to define the application of theappendix to which it applies. A normative appendix is an integral part of a Standard.Licensed to Simon Fraser on 28 Apr 2005.

20、E TEST FOR FLOW CONTROLLERS USED IN SHOWERS 24Licensed to Simon Fraser on 28 Apr 2005. For Committee WS-032 use onlyFOREWORDAs showers are significant consumers of water, this Standard has been revised to encourage the development of showers that will give a comfortable and effective shower even at

21、low water flow rates.A shower is essentially a tactile experience and what may look like a good shower may not be confirmed by use. The following factors, among others, influence the quality of a shower:(a) Water flow rate(b) Temperature drop Showers with significant temperature drops, which increas

22、e with distance from the head, could present a scalding hazard and may require greater heated water usage to achieve acceptable water temperatures. The ability of water to rinse soap is temperature sensitive; therefore, showers with a minimum temperature drop (drop in water temperature from the show

23、erhead to the lower limbs) are more effective for ablution purposes.The criterion for temperature drop in this Standard is based on what can be readily achieved by many showers currently on the market.(c) Spray pattern The spray pattern of a shower has two main features. The first is the shape of th

24、e cone of water emitted and the second is the distribution of spray within the cross-sections of the cone. Showers with wide cones can display two undesirable features: if the water spray is evenly distributed throughout the cone, a significant temperature drop may be felt with increasing distance f

25、rom the shower spray head; alternatively, if the spray is concentrated around the perimeter of the cone, the shower may have a hollow feel. In either case, the shower may present difficulties when washing and rinsing the lower body extremities.This Standard maintains a requirement for the angle of s

26、pread from the shower spray head of a cone. Consumer acceptance tests on different showerheads indicated a preference for shower spray heads with a mean spray spread angle of between 3 and 7.(d) Comfort and effectiveness Although the velocity of spray is a factor in the comfort and effectiveness of

27、a shower, a test for velocity of spray is not included in this Standard. High velocity sprays are uncomfortable and force the bather to reduce the flow rate, which may be beneficial for water conservation, but may also result in the shower becoming ineffective.Tests conducted on showerheads to aid i

28、n the development of this Standard indicated the following with respect to spray exit velocity:Velocity Effect23 m/s Comfortable spray46 m/s Stimulating spray10 m/s Painful sprayNo overall test for the comfort and effectiveness of a shower has yet been included in this Standard, of which velocity is

29、 a factor. Research is underway to develop such criteria, especially for showers with flow rates less than 7.5 L/m.NOTES:1 It is anticipated that the next revision of this Standard will include appropriate tests.2 Showers are required to meet the requirements of the Plumbing Code of Australia and th
