This European Standard was approved by CEN on 1 June 2020.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United Kingdom.

European foreword

This document (EN 13094:2020) has been prepared by Technical Committee CEN/TC 296 “Tanks for the transport of dangerous goods”, the secretariat of which is held by AFNOR.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2021, and conflicting national standards shall be withdrawn at the latest by January 2021.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

This document supersedes EN 13094:2015.

Compared with EN 13094:2015, the following are the principal changes that have been made:

a) changes to reflect the change in scope from low pressure to gravity-discharge applications;

b) updates to the normative references;

c) changes to the terms, definitions, symbols and abbreviations;

d) simplification of service equipment requirements by reference to regulatory requirements;

e) clarification of impact strength required at lower design temperatures;

f) new requirements on the cross-sectional shapes of shells for non-circular cross-sections, sumps and other external projections and cut-outs within the contour of a side or bottom of the shell;

g) clearer requirements on design verification;

h) expansion of provisions for the dynamic conditions used for tank design;

i) provisions for pressure conditions revised to reflect the change in scope;

j) clarification that maximum stress refers to maximum membrane stress;

k) expansion of requirements on shell thickness to clarify and include cut-outs;

l) addition of preferred location of tank top service equipment;

m) partial easing of restriction on longitudinal partitions;

n) additional requirements on pipes passing through the shell;

o) general revisions on the protection of service equipment mounted on the top of the tank;

p) new requirements for electrical bonding and earthing;

q) changes to the assessment criteria for welds not covered by either Annex D or EN 14025;

r) examination and testing of welds referred to EN 12972;

s) manufacturing tolerances referred to EN 12972;

t) new requirements for minimum shell marking;

u) tank plate requirements addressed by reference to regulatory requirements;

v) clarification and revision of the application of the different methods of design verification in Annex A;

w) addition of finite element analysis as a method of measurement of specific resilience in Annex B;

x) changes to clarify the informative examples of welding details in Annex D; and y) an addition to the bibliography.

This document has been submitted for reference in:

1 Scope

This document specifies requirements for the design and construction of metallic gravity-discharge tanks intended for the carriage of substances having a vapour pressure not exceeding 110 kPa (1,1 bar) (absolute pressure) at 50 °C.

NOTE 1 Gravity-discharge tanks have no maximum working pressure. However, during operation, pressure in the shell may occur, for example due to flow restrictions in vapour recovery systems or opening pressures of breather devices. It is important that these operating pressures do not exceed the test pressure of the tank or 0,5 bar, whichever is the highest.

This document specifies requirements for openings, closures, pipework, mountings for service equipment and structural equipment.

NOTE 2 This document does not specify requirements for items of service equipment other than pipes passing through the shell.

This document is applicable to aircraft refuelers that are used on public roads. It is also applicable to inter-modal tanks (e.g. tank containers and tank swap bodies) for the transport of dangerous goods by road and rail.

NOTE 3 This document is not applicable to fixed rail tank wagons.
