This criteria covers procurement actions for sanitary tapware. For the purpose of these criteria, sanitary tapware is defined as covering the following groups of products:
1) taps,
2) showerheads,
3) showers.
The definitions of these product groups are as follows:
• “tap” means a directly or indirectly, manually mechanically and/or automatically operated valve from which water is drawn.
• “showerhead” means;
a fixed overhead or side shower outlet, body jet shower outlet or similar device which may be adjustable, and which directs water from a supply system onto the user; or
a moveable hand held shower outlet which is connected to a tap with a shower hose and can be hung directly on the tap or on the wall with the aid of an appropriate support;
• “shower” means a combination of showerhead and interrelated control valves and/or devices packaged and sold as a kit;

Maximum available water flow rate The maximum available water flow rates to the basin/sink shall, independent of the water pressure, not exceed values presented in Table 1. Table 1 Maximum available water flow rates for sanitary tapware
Note [1]: Showerheads or showers with more than one spray pattern shall fulfil the requirement for the setting with the highest water flow. |
||||||||||||||||||||||||||
| Verification: | Products holding a relevant Type 1 Eco-label fulfilling the listed requirements will be deemed to comply. Otherwise, results of sanitary tapware testing according to the test procedure contained in the relevant EN standard (see the list in Table 2 below) or an equivalent standard shall be submitted together with the tender to the contracting authority. The testing shall be conducted at pressure of 1.5, 3.0 and 4.5 bar (± 0.2 bar) for products declared by the manufacturer as being suitable for high pressure installations (typically 1.0 to 5.0 bar) or at pressure of 0.2, 0.3 and 0.5 bar (± 0.02 bar) for products declared by the manufacture as being suitable for low pressure installations (typically 0.1 to 0.5 bar). The mean value of the three measurements shall not exceed the maximum water flow rate value indicated in Table 1. The testing shall be performed by laboratories that meet the general requirements of EN ISO 17025 or equivalent. A technical dossier from the manufacturer or other appropriate means of proof demonstrating that these requirements have been met will also be accepted.Table 2 EN standards for sanitary tapware;

Lowest maximum available water flow rate Lowest maximum available water flow rate of the sanitary tapware, independent on the water pressure, shall not be lower that the values given in Table 3: Table 3 Lowest maximum available water flow rates for sanitary tapware
Note [1]: Showerheads or showers with more than one spray pattern shall fulfil the requirement for the setting with the highest water flow. |

Temperature management (criterion not applicable for showerheads and for sanitary tapware that shall be fitted to a water supply that is already temperature controlled) Sanitary tapware shall be equipped with an advanced device or technical solution which allows for management of temperature. a) Sanitary tapware shall be equipped with a hot water barrier. Double lever/handle showers do not fulfil the criterion. |
||||||||||||||||||||||||||
| Verification: | Products holding a relevant Type 1 Eco-label fulfilling the listed requirements will be deemed to comply. Other appropriate means of proof will also be accepted, e.g. manufacturer/supplier statement specifying the type of solution used and its technical parameters, as appropriate, shall be submitted. Where a water supply is already temperature controlled the tenderer shall explain the specific technical property that makes the sanitary tapware specifically designed to be fitted to this form of system. | |||||||||||||||||||||||||
|
Time control for sanitary tapware for multiple users and high frequency use Sanitary tapware installed in non-domestic premises for multiple users and for frequent use (i.e. sanitary tapware used in public toilets or washrooms in schools, offices, in hospitals, swimming-pools and similar premises) shall allow for limiting time of a single water use (i.e. water volume consumed). This can be done by equipping the products with devices which stop water flow after certain time if they are not used (for example, sensors which stop water flow when a user leaves the sensor range) and/or after a set time period of use (for example, time limiters, which stop the water flow when the maximum flow time is reached). a) If the public authority is wishing to have a time-controlled system: For sanitary tapware equipped with time limiters the pre-set maximum flow should not exceed 15 seconds for taps and 35 seconds for showers. Nevertheless, the product shall be designed to allow the installer to adjust the flow time to the intended product’s application. b) If the public authority is wishing to have a sensor-controlled system: For sanitary tapware equipped with the sensor, the shut off delay time after usage shall not exceed 2 second for taps and 3 seconds for showers. Furthermore, the sanitary tapware equipped with a sensor shall be equipped with an inbuilt ‘security technical feature’ with a pre-set shut-off time of maximum 2 minutes in order to prevent accidents or the continuous water flow from taps/showers when not in use. |

| Verification: | Products holding a relevant Type 1 Eco-label fulfilling the listed requirements will be deemed to comply. Other appropriate means of proof will also be accepted, e.g. manufacturer/supplier statement specifying the type of solution used and its technical parameters, as appropriate, shall be submitted. Where a water supply is already temperature controlled the tenderer shall explain the specific technical property that makes the sanitary tapware specifically designed to be fitted to this form of system. | |||||||||||||||||||||||||

Exposed surface condition and quality of coating Sanitary products which have a metallic Ni-Cr coating (regardless of the nature of the substrate material) shall comply with the standard EN 248. |

| Verification: | Products holding a relevant Type 1 Eco-label fulfilling the listed requirements will be deemed to comply. Otherwise, results of sanitary tapware testing according to the test procedure contained in the EN 248 standard or equivalent shall be submitted together with the tender to the contracting authority for verification. The testing shall be performed by laboratories that meet the general requirements of EN ISO 17025 or equivalent. A technical dossier from the manufacturer or other appropriate means of proof demonstrating that these requirements have been met will also be accepted. | |||||||||||||||||||||||||

Reparability and availability of spare parts The product shall be designed in such a way that its exchangeable components can be replaced easily by the end- user or a professional service engineer, as appropriate. Information about which elements can be replaced shall be clearly indicated in the information sheet attached to the product. The tenderer shall also provide clear instructions to enable the end-user or trained experts, as appropriate, to undertake basic repairs. The tenderer shall further ensure that spare parts are available for at least five years from the date of purchase. |
