c
There is usually no acoustic classification for taps used in supply systems of type 2 and no specifications governing the
level of noise emissions from these water installations.
If supply pressures are such that excessive noise is generated it is recommended that pressure or flow regulators are fitted
in the system, or where practicable, taps conforming to the appropriate acoustic classification given in 13.3.5 are used.
NOTE If Taps are used at dynamic pressures outside the recommended operating range consideration should be given to
the following characteristics:
 the force required to operate the tap and diverter;
 diverter operation and flow rate;
 mechanical wear;
 acoustical performance.

7.1 General
This clause describes the test methods to verify the leaktightness of the complete tap and specifies the
corresponding requirements (see Table 6).
7.2 Test methods
7.2.1 Principle
The principle of the test consists of checking under cold water pressure the leaktightness of:
 obturator (see 7.4);
 complete tap (see 7.5);
 bath/shower diverter (either manual or automatic return) (see 7.6, 7.7, 7.8).
7.3 Apparatus
A hydraulic test circuit, capable of supplying the required pressures and of maintaining them throughout the
duration of the test.
7.4 Leaktightness of the obturator and of the tap upstream of the obturator
7.4.1 Procedure
Connect the tap to the test circuit:
a) with the outlet orifice open, and generally turned downwards, close the obturator using a torque of
(1,5 ± 0,1) Nm for nominal size ½ and (2,5 ± 0,1) Nm for nominal size ¾. If a stuffing box is used to ensure
tightness of the headwork, the packing gland shall be loosened before application of the closing torque;
b) apply to the inlet of the tap a water pressure of (1,6 ± 0,05) MPa (16,0 ± 0,5) bar for (60 ± 5) s.
7.4.2 Requirements
Throughout the duration of the test, there shall be no leakage at the obturator and no leakage or seepage through
the walls.
7.5 leacktightness of the tap downstream of the obturator
7.5.1 Procedure
Connect the tap to the test circuit:
a) if a stuffing box is used to ensure leacktightness of the headwork, ensure that the packing gland is tightened in
acordance with the manufacturer’s instructions;
b) with the outlet orifice(s) artificially closed, and generally turned downwards open the obturator(s);
c) apply to the inlet of the tap a water pressure of (0,4 ± 0,02) MPa (4,0 ± 0,2) bar and maintain it for (60 ± 5) s;
d) gradually reduce the pressure to (0,02 ± 0,002) MPa (0,2 ± 0,02) bar and maintain it for (60 ± 5) s.
7.5.2 Requirement
Throughout the duration of the test there shall be no leakage, or seepage through the walls.
7.6 leacktightness of manually operated diverter

8 Pressure resistance characteristics -mechanical performance under pressure
8.1 General
This clause describes the test method to verify the mechanical performance under high pressure and specifies the
test criteria.
8.2 Principle
The principle is to detect any deformation of the tap which might occur under cold water pressure. The test is
carried out both upstream and downstream of the obturator.
8.3 Apparatus
A hydraulic test circuit, capable of supplying and of maintaining the required pressures and of maintaining them for
the test duration.
8.4 Mechanical behaviour upstream - Obturator in the closed position
8.4.1 Procedure
a) Connect the tap to the test circuit;
b) with the obturator(s) closed apply at the tap inlet a static water pressure of (2,5 ± 0,05) MPa (25,0 ± 0,5) bar for
(60 ± 5) s;
c) check whether there is permanent deformation in any part of the tapware upstream of the obturator.
8.4.2 Requirement
For the duration of the test, there shall be no permanent deformation of any part of the tap.
8.5 Mechanical behaviour downstream - Obturator in the open position
8.5.1 Procedure
a) Connect the tap as supplied to the test circuit;
b) open the tap obturator(s) fully;
c) for taps with a flow rate regulator fitted apply at the tap inlet a dynamic water pressure of (0,4 ± 0,02) MPa
(4,0 ± 0,2) bar for (60 ± 5) s. For taps without flow rate regulator apply at the tap inlet, for (60 ± 5) s, the water
pressure needed to give a flow rate of 0,4 l/s ± 0,04 l/s through taps of nominal size ½ and a flow rate of
0,8 l/s ± 0,08 l/s through taps of nominal size ¾. For taps with removable flow rate regulator, the test is carried
out both with and without this regulator;
d) check whether there is permanent deformation in any part of the tap ware downstream of the obturator.
8.5.2 Requirement
No permanent deformation shall be produced in any part of the tap.

9 Hydraulic characteristics
9.1 General
This clause describes the test methods for measuring the flow rate of single and combination taps.
The test is not applicable to combination taps for ascending spray bidets or when the customer requires outlets of
special design e.g. bottle filling (see 6.5, special cases).
9.2 Test method
9.2.1 Principle
The value of the flow rate corresponding to a reference pressure is determined, the measurement being carried out
with the tap fully open. In the case of combination taps each side is
