For Germany this information leaet denes under "3.1 General" for the national
regulations: "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 dened 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 fullled.“
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 leaet "Leak tests of drinking water
installations with compressed air, inert gas or water" (January 2011) T 82-2011 of
the German Central Association for Sanitary, Heating and Air Conditioning (ZVSHK),
denes the following for Germany: "For reasons of practicability on the building site,
a modied 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 specied 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 dened:
Leak test with inert gases (e.g. nitrogen)
"In buildings with enhanced hygiene requirements such as medical facilities, hospi
-
tals, doctors' practices, the use of inert gases may be required to rule out conden-
sation of the moisture in the pipe."
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 ushed and therefore
released for connection and operation,
● the pipe system is lled using totally hygienic components,
● the system remains full from the leak test to commissioning and partial lling can
be avoided.
Drinkingwaterdirectiveintheversionof2ndofAugust2013,§11
For Germany the drinking water directive in the version of the 2nd of August 2013 in
§ 11 "Treatment materials and disinfection methods" denes that only treatment
materials contained in a list of the Federal Ministry of Health may be used for the
disinfection of drinking water. This list is maintained by the Federal Environment Ofce.

For Germany, further instructions for the "Cleaning and Disinfection of Drinking Water
Installations" can be taken from the Technical Rule - Worksheet DVGW W 557 (A)
October 2012 of the German Association of the Gas and Water Trade (DVGW).
Section 6 "Cleaning" species under 6.1 "General, aim of the cleaning": "Cleaning
must be implemented as the rst measure in case of an existing microbial contam
-
ination of the nature of the drinking water. It may be necessary to disinfect the
installation additionally after cleaning."
Section 6.3 "Cleaning methods" describes the ushing methods "ushing with water"
and "ushing with an a water/air mixture" which are basically familiar from EN 806-4.
Contaminations can enter the pipe system during new installation and repair work;
there may even be a danger of microbial contamination. Section 6.3.2.2 "Flushing
with a water/air mixture" explains: "To remove encrustations, deposits or bio-lms
in existing pipes, ushing with water and air is necessary to achieve an enhanced
cleaning performance. The full coverage turbulent ow causes locally high forces
to mobilise deposits. The water requirement is reduced considerably in comparison
with ushing with water."
Section 7 "Disinfection" describes the thermal and especially the chemical installa
-
tion disinfection as a discontinuous measure for the decontamination of a drinking
water installation in detail. "Installation disinfection must only be carried out by
specialist companies." Section 7.4.2 lists 3 "proven disinfection chemicals", hydrogen
peroxide H
2 O 2 , sodium hypochlorite NaOCl and chlorine dioxide ClO 2 , their respec-
tive application concentration and exposure time. For example, the application
concentration for hydrogen peroxide is 150 mg H
2 O 2 /l and the exposure time 24
hours. Appendix A contains further information about these disinfection chemicals,
e.g. about application and work safety. Appendix B contains statements on the
material resistance to the recommended disinfection chemicals.
