European foreword
This document (prEN 17066-2:2023) has been prepared by Technical Committee CEN/TC 413
“Insulated means of transport for temperature sensitive goods with or without cooling and/or heating
device”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.

1 Scope
The document applies to thermally insulated means of transport used for temperature sensitive goods
equipped with a cooling and/or heating device.
This document specifies the terminology, the requirements for thermal insulation, air tightness,
dimensioning of equipment with cooling and/or heating device for long distance and distribution
transport.
This document does not specify further land transport requirements with regard to dimensions,
weights, etc. Further this standard does not cover safety requirements or special requirements for
thermal containers covered by ISO 1496-2.
2 Normative references

constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3.1 General
3.1.1
compartment
insulated part of a container built for the carriage of the goods equipped or not with a cooling and/or
heating device
3.1.2
unconditioned compartment
compartment considered to have no evaporator or other cooling and/or heating devices or for which
they are inactive
3.1.3
distribution transport
tour including at least 2 locations of delivery and/or collection of goods
3.1.4
long-distance transport
uninterrupted transport of goods from a collection point to a delivery point without intermediate
loading and unloading
3.1.5
refrigerant
fluid used for heat transfer in a refrigerating system, which absorbs heat at low temperature and a low
pressure and rejects heat at a higher temperature and a higher pressure usually involving changes of
the state of the fluid
3.1.6
eutectic elements
elements (e.g. plates, tubes, etc.) intended for cold or heat charging, containing an inside eutectic
solution having the characteristic to change phase at a specific temperature
Note 1 to entry: Fixed eutectic elements are cooled or heated with a cooling and/or heating device. Movable
eutectic elements are cooled or heated in a temperature-controlled space at a temperature sufficient to achieve
the phase change.
3.1.7
goods
temperature sensitive products to be transported within a defined temperature range
3.2 Equipment
3.2.1
equipment
container equipped with a cooling and/or heating device in one or more compartments
3.2.2
multi-temperature equipment
container divided by insulated partition walls in two or more compartments and equipped with a
cooling and/or heating device for maintaining different temperatures
3.2.3
non-mechanically refrigerated equipment
equipment which, using a source of cold (natural ice, with or without the addition of salt, eutectic plates,
dry ice, with or without sublimation control, liquefied gases, with or without evaporation control, etc.)
other than a mechanical or absorption cooling device is capable of lowering the inside temperature at a
nominal outside temperature of a compartment, and thereafter maintaining it, at the required inside
temperature
Note 1 to entry: Some nominal outside and inside temperature are proposed in in Annex B.
3.2.4
mechanically refrigerated equipment
equipment either fitted with a cooling device, or served jointly with other units of transport equipment
by such an appliance, (fitted with either a mechanical compressor, or an absorption cooling device etc.)
which is capable of lowering the inside temperature at a nominal outside temperature of a
compartment, and thereafter maintaining it, at the required inside temperature
3.2.5
heated equipment
equipment fitted with a heating device, which is capable of raising the inside temperature of a
compartment to, and thereafter maintaining it at a minimum temperature of + 12 °C, with a nominal
outside temperature
3.2.6
partition wall
fixed or movable, longitudinal or transversal, insulated wall also known as bulkhead between different
conditioned and/or unconditioned compartments inside a compartment
3.2.7
cooling device
system which lowers and/or maintains temperature in a compartment
3.2.8
heating device
system which increases and/or maintains temperature in a compartment
3.2.9
start/stop operation
automatic and usually electronic process which stops the thermal engine of the refrigeration system
when one temperature limit is reached and starts when the other one is exceeded
Note 1 to entry: In this mode besides the controller the refrigeration compressor, fans of the condenser and
evaporator are stopped.
