3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1
cryogenic fluid (refrigerated liquefied gas)
gas which is partially liquid because of its low temperature ). In the context of all parts of this standard the
(refrigerated but) non-toxic gases and mixtures of them given in Table 1 are referred to as cryogenic fluids

) This includes totally evaporated liquids and supercritical fluids.

3.2
large transportable cryogenic vessel (tank)
thermally insulated vessel of more than 1000 l intended for the transport of one or more cryogenic fluids, consisting
2)
of an inner vessel, an outer jacket , all of the valves and equipment together with any additional framework, this
large transportable cryogenic vessel representing a complete assembly ready for putting into service
3.3
thermal insulation
non-vacuum interspace between the inner vessel and the outer jacket. The space is filled with material to reduce
the heat transfer between the inner vessel and the outer jacket
3.4
2)
inner vessel
vessel intended to contain the cryogenic fluid
3.5
2)
outer jacket

technical documents delivered by the manufacturer to the owner consisting of :
all certificates establishing the conformity with this standard (e.g. material, pressure test, cleanliness, safety
devices);
a short description of the vessel (including characteristic data etc.);

2) The expressions 'inner vessel' and 'outer jacket' where originally introduced for vacuum insulated vessels. They are used in

4 General requirements
The large transportable cryogenic vessel shall safely withstand the mechanical and thermal loads and the chemical
effects encountered during pressure test and normal operation. These requirements are deemed to be satisfied if
clauses 5 to 9 are fulfilled. The vessel shall be marked in accordance with clause 10, tested in accordance with
clause 11 and clause 12 and operated in accordance with EN 14398-3.

3) see ADR 2001, Chapter 3.2, Table A, column 13: TU 19
These requirements shall be applied to fixed tanks (of tank-vehicles or tank-wagons), demountable tanks, and tank-
containers (TC) for refrigerated liquefied gases in the sense of the regulations of the transport of dangerous goods.
5 Mechanical loads
5.1 General
The large transportable cryogenic vessel shall resist the mechanical loads mentioned in clause 4 without such
deformation which could affect safety and which could lead to leakage. This requirement can be validated by:
the calculation;
the calculation and pressure strengthening method (see EN 14398-2);
the calculation and experimental method.
The mechanical loads to be considered are given in 5.2 and 5.3.
5.2 Load during the pressure test
The load exerted during the pressure test is p1,3ps where
t
p = test pressure (in bar);
t
p = allowable working pressure (= relief device set pressure) (in bar).
s
5.3 Other mechanical loads during normal operation
5.3.1 The following loads shall be considered to act in combination where relevant:
a pressure equal to the maximum allowable working pressure in the inner vessel and pipework;
the pressure exerted by the liquid column when filled to capacity;
loads produced by the thermal movement of the inner vessel, outer jacket and interspace piping;
loads imposed in lifting and handling fixtures (at the vessel);
load due to dynamic effects, when the vessel is filled to capacity, giving consideration to:
the inner vessel support system including attachments to the inner
