1 Scope
This European Standard specifies the fundamental requirements for large transportable non-vacuum insulated
cryogenic vessels and designed to operate above atmospheric pressure.
This standard applies to large transportable non-vacuum insulated cryogenic vessels for fluids as specified in 3.1
and is not applicable to such vessels designed for toxic fluids.
2 Normative references
This European Standard incorporates by dated or undated references, provisions from other publications. These
normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).

3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1
cryogenic fluid (refrigerated liquefied gas)
1
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

1
) 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
normally not gas-tight weather protection of the thermal insulation and of the inner vessel
3.6
normal operation
intended operation of the vessel at a pressure not greater than the maximum allowable working pressure including
the handling loads defined in 3.7
3.7
handling loads
loads exerted on the transportable cryogenic vessel in all expected situations of transport including loading,
unloading, moving lifting equipment
3.8
documentation
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
this set of standards to be consistent with all standards about cryogenic vessels, but in the case of the outer jacket with another
meaning in this set of standards.
