This standard specif ies a method to confirm the certification criteria and conformance of Ecolabel of the water saving faucets having a water saving function installed at the end of water pipes such as a single faucet, hot water and cold water mixed faucets or a stop valve among faucets used for supplying water with less than use pressure of 735kPa (hereinafter referred to as faucet), and valve products having a water saving function by stopping supply or water, automatically closing the value or supplying the specified amount of water. However, faucets for special use such as drinking water faucets, faucets for fountains and faucets for toilets shall be excluded.

The criteria shall apply to single faucet, cold and warm water mixed faucet or stagnant water faucet the water faucet (hereafter referred to as "faucet") used in water supply/bath supply with less than the usage pressure of 7.5kgf/㎠ 735kPa, to the water-saving faucet, which shall be set up at the end of water pipe and have water-saving effect, and to the valve that have water- saving effect through the function of immediate water-stopping, self-closing and fixed-quantity water-stopping. However, faucets for special use such as ones for drinking water, fountain and toilet shall be excluded.

All producers and distributors of sanitary fittings can apply to use the energy label for sanitary fittings. Only products available on the Swiss market may bear the voluntary energy label. The use of the Swiss voluntary energy label for sanitary fittings abroad is the responsibility of the manufacturers and distributors concerned. The energy label indicates the amount of energy used. In the case of sanitary fittings – showers and taps – this is the amount of energy used to heat the water used. Consequently, only hot water taps and showers can receive the label; cold water taps cannot. Mixer taps can only receive the energy label if they are clearly indicated as such.

A water‑use product or water‑saving product of any of the following kinds is a WELS product: (a) tap equipment that is for use over a fixed basin, sink or laundry tub, other than: (i) tap equipment that is for use exclusively over a bath or spa; and (ii) thermostatic taps; and (iii) bidet taps; and (iv) taps that are part of an appliance (such as a chilled or boiling water dispenser); (b) fixed showers that are for use exclusively for personal bathing, other than: (i) emergency deluge showers; and (ii) safety showers; (c) electric dishwashers that are intended for household use; (d) electric clothes washing machines that are intended for household use, including such machines that are: (i) cold wash only; or (ii) combination clothes washing machine dryers; (e) lavatory equipment that uses water, including toilets, cisterns, pans and associated flushing devices; (f) urinal equipment that uses water, including associated flushing devices; (g) flow controllers that are: (i) for use in a product that is a WELS product under any of paragraphs (a) to (d); and (ii) offered for supply separately from the product (whether or not they are also offered for supply as a component of the product).

This specification establishes the criteria for a flushing urinal under the U.S. Environmental Protection Agency’s (EPA’s) WaterSense® program. It is applicable to:

This specification establishes the criteria for a tank-type high-efficiency toilet under the U.S. Environmental Protection Agency’s (EPA’s) WaterSense program. It is applicable to: • Single-flush, tank-type gravity toilets; • Dual-flush, tank-type gravity toilets; • Dual-flush, tank-type flushometer tank (pressure-assist) toilets

This specification establishes the criteria for high-efficiency lavatory faucets and faucet accessories under the U.S. Environmental Protection Agency’s (EPA’s) WaterSense® program. It is applicable to lavatory faucets, lavatory faucet accessories specifically designed to control the flow of water, and any other lavatory faucet technologies that meet these performance specifications. This specification applies to lavatory faucets in private use, such as in residences, and private

This specification establishes the criteria for showerheads labeled under the U.S. Environmental Protection Agency’s (EPA’s) WaterSense program. Water-saving showerheads that earn the WaterSense label must demonstrate that they use no more than 2.0 gpm. It is applicable to showerhead fixture fittings, inclusive of showerheads, rain showers, and hand-held showers, as defined in the ASME A112.18.1/CSA B125.1 Plumbing Supply Fittings standard. "Showerhead” also includes rain showers and handheld showers.

The following devices are considered within the scope of this Specification: - Simple flush toilets, gravity type; - Dual flush cisterns, gravity type; - Double-acting flush toilets (with discharge interruption), gravity type. Conditions for the attribution of water efficiency labels to cisterns are available in Table 1 page 3 of the document.

This policy applies to washbasin taps, kitchen taps, and urinal flowmeters.
