This European Standard establishes the requirement for the design and use of vitreous enamel coated bolted
cylindrical steel tanks for the storage or treatment of water or municipal or industrial effluents and sludges.
This European Standard applies to the design of the tank and any associated roof and gives guidance on the
requirements for the design of the foundation.
This European Standard applies where:
a) the tank is cylindrical and symmetrical on plan and is mounted on a load-bearing base substantially at or
above ground level;
b) the multiple of the tank diameter in meters and the wall height in meters has a value within the range
5 to 500;
c) the tank diameter does not exceed 100 m, and the total wall height does not exceed 50 m;
d) the stored material has the characteristics of a liquid exerting negligible friction force in the tank wall; the
stored material may be undergoing treatment as part of a municipal or industrial effluent treatment
process;
e) the internal pressure above the liquid does not exceed 50 kPa and the internal partial vacuum above the
liquid does not exceed 10 kPa;
f) the walls of the tank are vertical;
g) the floor of the tank is substantially flat at its intersection with the wall; the floor of the tank may have a
rise or fall built in to allow complete emptying of the tank contents. The slope should not exceed 1:100;
h) there is negligible inertial and impact load due to tank filling;
i) the minimum thickness of the tank shell is 1,5 mm;
j) the material used for the manufacture of the steel sheets is carbon steel; (tanks constructed of sheets
made from aluminium or stainless steel are outside the scope of this European Standard),
k) the temperature of the tank wall during operation is within the range - 50 ºC to + 100 ºC under all
operating conditions.
This European Standard also gives details of procedures to be followed during site installation and for
inspection and maintenance of the installed tank.
It does not apply to chemical reaction vessels.
It does not apply to tanks fitted with floating roofs.
It does not cover resistance to fire.
Diese Europäische Norm legt die Anforderungen an Gestaltung und Gebrauch von emailbeschichteten, verschraubten, zylindrischen Stahlbehältern für die Speicherung und Behandlung von kommunalen oder industriellen Abwässern fest. Diese Europäische Norm gilt für die Gestaltung des Behälters und aller zugehörigen Dächer und liefert Leitlinien für die Anforderungen an die Gestaltung des Fundamentes. Diese Europäische Norm enthält ebenfalls Einzelheiten zu Verfahren, die während der Montage auf der Baustelle sowie bei Inspektion und Instandhaltung des eingebauten Behälters zu befolgen sind. Diese Norm gilt weder für chemische Reaktionsbehälter, Schwimmdach-Tanks noch Brandsicherheit.
