3 Terms and definitions
For the purposes of this standard, the terms and definitions given in ISO 668, ISO 1161. ISO 1496-1. ISO 6346, IEC 60309-2 and the following apply.
3.1
thermal container
insulated container
freight container having insulating walls, doors, floor and roof designed to delay the rate of heat transmission between the inside and the outside of the container
3.2
refrigeration container
(expendable refrigerant) thermal container served by a unit using a means of cooling such as liquefied gases, with or without evaporation control (ERU)
3.3
picture frame
opening in one end of a thermal container to accommodate an integral refrigeration unit
3.4
built-in front mechanically refrigerating and heated container
thermal container with built-in recess for a refrigeration and heating unit
3.5
heated container
thermal container with a heat producing unit
3.6
modified atmosphere
controlled atmosphere
system installed in a thermal container served by a refrigeration unit, capable of generating and/or maintaining gas concentration levels different to those of the air outside the container
3.7
removable equipment
power-generating unit or other equipment designed to be attached or detached from a thermal container
3.8
internally
totally within the external dimensional envelope of the container as defined in ISO 668
3.9
externally
partially or totally outside the external dimensional envelope of the container as defined in ISO 668
Note: It is implicit in this definition that a unit located externally needs to be removable or retractable to facilitate transport in certain modes.
3.10
batten
member installed on the inside walls of the container to hold the cargo away from the wall to provide an air passage
Note: The member maybe integral with the wall, fastened to the wall or added during cargo loading.
3.11
bulkhead
partition providing a plenum chamber and/or air passage for either return or supply air
Note : The partition maybe an integral part of the unit or a separate member.
3.12
load line
mark on the interior surface of a thermal container above which cargo should not be stowed
3.13
T-floor
section of floor, usually in aluminium, in the profile of the letter “T” for supporting cargo and distributing air
3.14
fresh air vent
adjustable orifice to allow a supply of outside air into a mechanical refrigeration container
Note: A mechanical refrigeration container is a thermal container served by a mechanical refrigeration unit (MRU), see Annex H.
3.15
floor drain
self-sealing floor orifice to allow the expulsion of condensate
3.16
vacuum valve
valve to prevent the development of excessive air pressure differential between inside and outside of the thermal container
3.17
defrost drain
orifice for discharging condensate from the cooling coil
3.18
pin mounting
mounting system using two vertical pins engaging in sockets built into the front header
3.19
lower mounting point
threaded receptacle to which the lower two corners of the removable equipment are fastened
3.20
new thermal container new insulated container
freight container having insulating walls, doors, floor and roof that has been manufactured within the previous 7 days and with maximum heat-leakage rate
3.21
high ambient temperature
temperature above 50℃ at which the MRU is expected to operate without functional restrictions
3.22
aged thermal container
thermal container with aged polyurethane foam and with a heat-leakage rate 20 % higher than the Umax value given in Table 2
