on vertical surface, diverter, fixed outlet, nominal flow rate, with acoustic group I, EN 817.
5 Marking and identification
5.1 Marking
Sanitary tapware shall be marked permanently and legibly with the manufacturer’s or agent’s name or
identification:
— of the sanitary tapware on the body, handle or spout. This marking shall be visible after installation;
— of the obturator on the on/off obturator, (not applicable when the on/off obturator is of a special
design to suit the body or when manufactured by the same manufacturer of the sanitary tapware).
This marking does not need to be visible after installation.
NOTE 1 Permanently in this case means not removable without direct intent (e.g. may require the use of a tool
or implement to remove).
NOTE 2 Visible after installation can be visible by use of a mirror or on the underside of a spout etc. This list is
not exhaustive.
5.2 Identification
5.2.1 Identification of inlets
Normal convention is to configure sanitary tapware with the cold water inlet on the right side of the
product when the product is viewed from the front.
If the product is configured conventionally, no identification of the inlets is required.
If the product is not configured conventionally, or the product can be installed in multiple orientations
that can be conventional or non-conventional, hot or cold inlets shall be identified as follows:
— cold: Colour blue or words/letters;
— hot: Colour red or words/letters.
In these cases, only one of the inlets needs to be identified. This marking need not be permanent.
5.2.2 Identification of control device (s)
Normal convention is where the sanitary tapware’s control device operates in two planes [on (up)/off
(down) plane and hot/cold in the left/right plane] when the product is viewed from the front.
If the product is configured conventionally, no identification of the flow control device is required.
In all other cases, for control devices, to facilitate the understanding of the function, the device shall be
permanently identified as follows:
— colour blue for cold;
— colour red for hot;
— or words/letters or and other suitable means e.g. symbols, arrows, etc.
6 Materials
6.1 Chemical and hygiene requirements
All materials coming into contact with water intended for human consumption shall present no health
risk nor cause any change to the water in terms of quality, appearance, smell or taste.
NOTE Attention is drawn to existing national regulations concerning the use and/or the characteristics of
these products while awaiting the adoption of verifiable European criteria for testing materials in contact with
water intended for human consumption.
6.2 Exposed surface condition and quality of coating
Exposed surfaces shall comply with the scope and requirements of EN 248.
7 Backflow protection
Backflow protection shall be provided using appropriate devices referenced in EN 1717.
Appropriate devices may include the use of an airgap or the specific product design.
In the case of a diverter with automatic return being considered to provide backflow protection, it shall
comply with the requirements of EN 14506.
Check valves shall comply with EN 13959.
8 Sequence of testing
This standardized test sequencing, detailed in Table 3, helps to present a consistent approach while
minimizing the number of samples required for testing. The overall collection of test results shall be
combined for an overall type test outcome.

9.3 Outlet dimensions
Outlet dimensions shall be as specified in Table 5, Figure 4, Figure 5, Figure 6.
When nozzle outlets are used with flow rate regulators/flow straighteners/flow aerators conforming
with EN 246, the manufacturing tolerances chosen for the connecting threads of the outlets shall be
compatible with those of the connecting threads of the flow rate aerators to ensure interchangeability.

9.5 Special cases
Sanitary tapware intended for special applications e.g. for installation on sanitary appliances not
conforming with European Standards, or where dimensional interchangeability is not a requirement
can incorporate dimensional deviations provided that:
— All other requirements of this document are satisfied;
— The air gap dimension E ≥ 25 mm or a backflow prevention device is provided to maintain suitable
backflow protection;
— The D1, D2 dimension shall be coordinated with the appropriate sanitary appliance.
NOTE The dimensions E, D1 and D2 can be found in the Figure 4, Figure 5 and Figure 6.
10 Leaktightness characteristics
10.1 Principle
These tests are designed to verify the leaktightness of the complete sanitary tapware product.
These tests are conducted using cold water.
10.2 Apparatus
A hydraulic test circuit, capable of supplying the required static and dynamic pressures and of
maintaining them throughout the duration of each test.
10.3 Leaktightness of the obturator and of the tap upstream of the obturator(s) with the
obturator in the closed position
10.3.1 Procedure
a) Connect all inlets of the sanitary tapware to the test circuit in its position of use;
b) Open the obturator, allow water to flow to purge air from the system;
c) With the outlet open close the obturator;
d) Apply to each inlet of the sanitary tapware a water pressure of (1,6 ± 0,05) MPa [(16,0 ± 0,5) bar]
for (60 ± 5) s;
e) During this period, operate the temperature control device over the full operating range (excluding
single sequential mixing valve).
10.3.2 Requirements
Throughout the duration of the test, there shall be no leakage of the obturator e.g. through the outlet or
through any other part of the sanitary tapware product.
10.4 Leaktightness downstream of the obturator
10.4.1 General
Not applicable if the outlet cannot be artificially closed.
10.4.2 Procedure
a) Connect all inlets of the sanitary tapware to the test circuit in its position of use;
b) Allow water to flow to purge air from the system and close the obturator;
c) Artificially close the outlet orifice and open the obturator;
d) Apply to each inlet of the sanitary tapware a static water pressure of (0,4 ± 0,02) MPa
[(4,0 ± 0,2) bar] for (60 ± 5) s;
e) During this period, operate the temperature control device over the full operating range (excluding
single sequential mixing valve);
f) Within (5 ± 1) s, reduce the static water pressure to (0,02 ± 0,002) MPa [(0,2 ± 0,02) bar] and
maintain it for (60 ± 5) s;
g) During this period, operate the temperature control device over the full operating range (excluding
single sequential mixing valve).
10.4.3 Requirements
Throughout the duration of the test, there shall be no leakage of the sanitary tapware product.
10.5 Leaktightness of manually operated diverters
10.5.1 General
This test is designed for sanitary tapware products that have manually operated diverters typically
bath/shower or shower/shower diverters but also products that may have multiple outlets.
10.5.2 Procedure
a) Connect all inlets of the sanitary tapware to the test circuit in its position of use;
b) Open the obturator, allow water to flow;
c) Put the diverter into the position outlet 1 (e.g. bath) and artificially close outlet 1 and keeping
outlet 2 (and any other outlets in the case of multiple outlets) open;
d) Apply a static water pressure of (0,4 ± 0,02) MPa [(4,0 ± 0,2) bar] and maintain it for (60 ± 5) s;
e) Check that leaktightness is maintained at outlet 2 (and any other outlets in the case of multiple
outlets);
f) Within (5 ± 1) s, reduce the static water pressure to (0,02 ± 0,002) MPa [(0,2 ± 0,02) bar] and
maintain it for (60 ± 5) s;
g) Check that leaktightness is maintained at outlet 2 (and any other outlets in the case of multiple
outlets);
h) Open outlet 1, put the diverter in the outlet 2 position, artificially close outlet 2;
i) Apply a static water pressure of (0,4 ± 0,02) MPa [(4,0 ± 0,2) bar] and maintain it for (60 ± 5) s;
j) Check that leaktightness is maintained at outlet 1 (and any other outlets in the case of multiple
outlets);
k) Within (5 ± 1) s, reduce the static water pressure to (0,02 ± 0,002) MPa [(0,2 ± 0,02) bar] and
maintain it for (60 ± 5) s;
l) Check that leaktightness is maintained at outlet 1 (and any other outlets in the case of multiple
outlets);
m) Repeat as necessary for diverters with more than 2 outlets.
10.5.3 Procedure where an outlet(s) cannot be artificially closed
a) Connect all inlets of the sanitary tapware to the test circuit in its position of use;
b) Open the obturator, allow water to flow;
c) Put the diverter into posi
