5.3 K-value measurement
5.3.1 Testing conditions
Distinction is made between containers in general and tanks during testing. The quality of the thermal
insulation of the container is tested in the steady-state conditions using the internal heating method.
The heat dissipated by the electrical resistance fan heaters shall not exceed a heat dissipation of
2
1 W/cm and the heater units shall be protected by a casing of low emissivity.
The air in the conditioned test room shall be continuously circulated in horizontal and longitudinal
direction so that its velocity at a distance of 100 mm of the walls of the container shall be between
1 m/s and 2 m/s, except for small container where the air is limited between 0,4 m/s and 0,6 m/s. The
air velocity shall be verified in the centre of the lateral surfaces.
For determination of the internal and external temperatures the accuracy of the temperature
measurement chain shall be within ± 0,3 K.
All temperature and active power consumption measurements shall be made with automatic recording
devices. All temperature sensors shall be measured at the same time (that means within a period of less
than 10 s) and the arithmetic mean shall be calculated for each recorded values. The arithmetic mean of
each individual temperature sensor shall be recorded for all intervals during a sequence of 120 s
maximum.
Electrical cable losses between the heat input measuring instrument and the tested body shall be
established by a measurement or calculation and subtracted from the total heat input measured.
Equipment for the generation and distribution of heat shall be arranged on the inside of the empty
container. The heat exchangers or electrical heating appliances shall be fitted with fans sufficient to
obtain an air flow of 60 ± 15 % times per hour related to the inner volume of the tested container, in the
case of small containers 40 ± 20 %, to ensure that a homogeneous temperature inside the container.
Each measurement involves uncertainties caused by the measurement arrangement, the method of
measurement and the measuring instruments, as well as the readings.
The calculated overall uncertainties shall not exceed the limits of Table 1.
5.3.2 Test procedure
The container shall be located at minimum 0,30 m from the floor.
The container shall be fitted with temperatures measuring sensors located at a distance of 100 mm
from the walls internally and externally. The number and position of temperature sensors shall be
determined, depending of the container inner volume, according to Table 2:

For a compartment which is a fixed part of a container, the temperatures should be measured at the
corresponding points of this compartment.
After closing doors and hatches, the equipment for the generation and distribution of heat and the
measurement devices for determination of the heating capacity and the heat equivalent of the air-
circulating fans shall be started up.
The test shall be continued until the steady-state conditions have been verified.
After reaching the steady-state conditions, the temperature difference between the points of
measurement showing the highest and lowest temperatures shall not exceed 2 K except tanks (see C.1)

4 Requirements for containers and kits
4.1 General
The container, insulation and body kits shall be designed in order to reach the relevant K-value for its
application:
4.2 Materials and components
The materials shall be durable and shall not encourage the development of mould or emit odours.
Internal and external coverings shall be resistant to wear and capable of being cleaned effectively and
hygienically. They shall not crack, chip, flake, rub off or soften under normal conditions of use or during
cleaning. Detergents and disinfectants, cleaning and disinfection procedures, approved by the
equipment manufacturer, shall be used.
Metal parts, used in the construction of equipment, shall have resistance to corrosion appropriate to
their location and function.
Internal and external finishes and insulation shall be resistant to temperature ranges intended to be
applied
When the container is intended to be loaded with unpacked foodstuff, the internal covering materials
and articles shall comply to further requirements for materials and articles intended to come into
contact with foodstuffs, if applicable.
The materials shall be resistant to moisture and shall neither be toxic nor contaminate the foodstuff.
Safety devices already integrated in the vehicle (for example: inside unlocking of doors, exit aids) shall
not be interfered by fitting of the insulation the load space.
4.3 Thermal insulation
4.3.1 General
When selecting the insulating material, it shall be ensured that it:
— is odourless and resistant to uptake of odours;
— shows only little moisture absorption;
— is decay-resistant;
— shows dimensional stability in the temperature range from −40°C to +80°C and has sufficient
strength and dimensional stability for all intended ranges of application;
— has a good thermal insulation with minimal ageing properties.
NOTE For reasons of energy savings, quality of the good temperature during transport and operational costs,
the level of insulation of the container could take into account:
— the temperature difference between inside and outside temperature ranges which is intended to be
met during use of the container;
— the effectiveness of European pallet transport and the linked dimensions.
For energy savings of the cooling and/or heating devices only, not including traction energy
consumption, it is strongly recommended to choose a K-value with the following formula:

K− tt−
( )
e i
Example:
t = 30 °C;
e
t = −20 °C;
i
k ≤ 0,4.
When it is not possible to follow this rule, due to required dimensions, for pallet transport for example,
the manufacturer could design the equipment and its air circulation to maintain the good temperature
according to the outside and inside temperatures required by the customer.
When any panel thickness is reduced due to fittings (e.g. wheel box, mechanical reinforcements,
accessories), the calculated K-value of the reduced thickness panel shall (calculated on a conduction
heat transfer method) be equal or lower than 2,5 × expected K-value of the class.
4.3.2 Seals
The doors or other openings and their frames shall be provided with sufficient seal.
When selecting the seals, it shall be ensured that:
— they are fully serviceable at temperatures between −40 °C and +80 °C;
— the seals shall be fitted such that they can be replaced;
— they can be cleaned easily and thoroughly.
The usual detergents and disinfectants as well as cleaning and disinfection procedures shall not
negatively affect the seals.
4.4 Surfaces and inner volume
The surface areas S and S have to be determined.
e i
For insulated vans the external surface area shall be considered as the outer skin of each insulated
panel. If possible, the manufacturer shall provide drawings and calculation of the inside and outside
surfaces.
If it's not possible the manufacturer shall provide drawings and calculations according to schemes and
formula as follows:

If above not possible, the internal surface has to be measured according to the figures and formula and
the external surface shall be calculated taking the thickness of all panels as 60 mm.
a) First step: Measuring of the inner dimensions and calculation of the inner surface. The inner
dimensions will be determined with different cuts in longitudinal, transversal and horizontal
directions. The inner surface can be alternatively determined with envelope dimensions in different
levels;
b) Second step: Measuring of the heat transmission for the calculation of the K-value based on the
calculated inner surface;
c) Third step: Calculation of the average insulation thickness under the assumption that ʎ has a value
of 0,025;
d) Fourth step: Calculation of the average surface;
e) Fifth step: Conversion of the under step 2 measured k value on the average surface.
Tanks are calculated taking into account all geometrical surfaces areas, as cylinder, cone, partial cone
shaped and their ends, as ellipse, ovoid, torns, lone, sphere.

container. The heat exchangers or electrical heating appliances shall be fitted with fans sufficient to
obtain 40 to 70 air charges per hour related to the inner volume of the tested container and to ensure
that the greatest temperature difference between the points of measurement showing the highest and
the lowest temperatures does not exceed 2 K or both the external and internal air temperatures of the
container after reaching the steady-state conditions.
Each measurement involves uncertainties caused by the measurement arrangement, the method of
measurement and the measuring instruments, as well as the readings.
