European standard EN 806-4:2010
Based on the currently valid European directive 98/83/EC "on the quality of water
for human consumption", the European standard EN 806-4:2010 "Specifications for
installations inside buildings conveying water for human consumption – Part 4:
Installation" was adopted by the European Committee for Standardisation (CEN) on
the 23rd of February 2010 and had to receive the status of a national standard in
all European countries by September 2010. This standard defines Europe-wide
regulations for the commissioning of drinking water installations, e.g. for filling,
pressure testing, flushing and disinfection for the first time.
Section 6 of EN 806-4:2010 describes the "filling and hydrostatic pressure testing
of installations inside buildings for water for human consumption". "Installations
inside buildings must be subjected to pressure testing. This can be done either with
water or, if national regulations allow, oil-free, clean air with low pressure or inert
gases may be used. The possible risk from high gas or air pressure in the system
must be considered." However, apart from this note, the standard EN 806-4:2010
contains no test criteria whatsoever for testing with compressed air.
Section 6.1 of EN 806-4:2010 offers 3 test methods A, B, C for hydrostatic pressure
testing depending on the material and size of the installed pipes. The test methods
differ in different test sequences, pressures and times.
Section 6.2. of EN 806-4:2010 refers to this: "The drinking water installation must
be flushed with drinking water after installation and pressure testing as well as
immediately before commissioning." "If a system is not put into operation immediately
after commissioning, it must be flushed at regular intervals (up to 7 days)." Pressure
testing with compressed air is recommended if this demand cannot be fulfilled.
Section 6.2.2. of EN 806-4:2010 describes flushing with water.
Section 6.2.3. of EN 806-4:2010 describes flushing with a water/air mixture.
Information leaflet T 82-2011 of the German Central Association for Sanitary,
Heating and Air Conditioning
For Germany the information leaflet T 82-2011 "Leak Tests of Drinking Water Instal-
lations with Compressed Air, Inert Gas or Water" of the German Central Association
for Sanitary, Heating and Air Conditioning defines the following for the national
regulations under "3.1 General": "Due to the compressibility of gases, the rules for
the prevention of accidents "Working on Gas Systems" and the "Technical Rules for
Gas Installations DVGW-TRGI" must be observed for physical and safety reasons
when conducting pressure tests with air Therefore, the test pressures have been
defined as maximum 0.3 MPa (3 bar), the same as for load and leak tests for gas
pipes, in agreement with the responsible industrial liability insurance association
and based on these rules. The national regulations are thereby fulfilled."
With regard to the test methods A, B and C offered in section 6.1 of EN 806-4:2010
for pressure testing with water, information leaflet T 82-2011 of the German Central
Association for Sanitary, Heating and Air Conditioning defines the following for
Germany: ""For reasons of practicability on the building site, a modified method
based on practical tests which can be used for all materials and combinations of
materials was chosen. The test time has been extended in relation to the time
specified in the standard to allow even the slightest leaks to be detected. Test method
B in accordance with DIN EN 806-4 is the basis for conducting the leak test with
water for all materials." The following is defined:
Leak testing with compressed air is to be conducted when
● a longer standstill time between the leak test and commissioning, especially at
average ambient temperatures > 25°C, is to be expected to rule out possible
bacterial growth,
● the pipe system cannot remain completely full from the leak test to commissioning,
e.g. during a frost period,
● the corrosion resistance of a material in a partially drained line is endangered
Leak testing with water can be conducted when
● changing of the water can be ensured at regular intervals, after seven days at
the latest, from the time of the leak test to commissioning of the drinking water
installation. Additionally when
● it is ensured that the house or building water connection is flushed and therefore
released for connection and operation,
● the pipe system is filled using totally hygienic components,
● the system remains full from the leak test to commissioning and partial filling can
be avoided.
Information leaflet T 84-2004 of the German Central Association for Sanitary,
Heating and Air Conditioning
For Germany information leaflet T 84-2004 "Flushing, Disinfection and Commissioning
of Drinking Water Installations" of the German Central Association for Sanitary,
Heating and Air Conditioning confirms and extends the methods for flushing and
disinfection of drinking water installations largely defined already in EN 806-4:2010.
It deals in particular with chemical disinfectants and describes thermal disinfection.

sponds to the mains voltage. Only use sockets/extension leads with a functioning
PE contact. The function of the PRCD fault current circuit breaker (Fig. 1 (1))
must be checked every time before start-up and before beginning work:
1. Plug the mains plug into the socket.
2. Press the RESET button (2), the PRCD control lamp (Fig. 1 (39)) lights red
(operating state).
3. Pull out the mains plug, the PRCD control lamp (39) must go out.
4. Plug the mains plug back into the socket.
5. Press the RESET button (2), the PRCD control lamp (39) lights red (oper-
ating state).
6. Press the TEST button (3), the PRCD control lamp (39) must go out.
7. Press the RESET button (2) again, the PRCD control lamp (39) lights red.
The control lamp (Fig. 2 (5)) lights green. REMS Multi-Push is ready for
operation after about 10 s.
