— measurement on linear dimensions shall be to an accuracy of ±2 mm.
5.3.2.8 Alternative for filling test packages
Alternative filling test packages having the dimensions shown in Table 4 and density of (480 ± 80) kg/
m can be used, except for rows (see 5.3.3.3.1) and columns containing M packages, see Figure 8.
This test package may be a box made of plastic material of any density, and of 1 mm nominal thickness.
Cellular or foam material shall not be used. The case shall not incorporate any protrusions that would
cause the vertical separation of packages in a stack. Opposite faces shall be substantially parallel,
and moulding draft shall be the minimum practicable. Seams or joints of the case shall not result in
protrusions sufficient to cause significant air gaps between adjacent packages.
The contents shall be water containing 0,08 % of para-chlorometa-cresol and 0,5 % of sodium chloride,
soaked into a porous material such as a natural, plastics or cellulose sponge.

5.3.3 Preparation of test cabinet
5.3.3.1 Cabinet selection, installation and positioning within the test room
Each refrigerated cabinet intended to be tested, unless a prototype, shall be selected from stock or
routine production and shall be representative as to construction and adjustment.
The cabinet, including all components required for normal operation, shall be assembled, set
up and sited as it would be installed in service as far as practicable and in accordance with the
manufacturer's instructions. All permanently located accessories required for normal use shall be in
their respective places.
Cabinets shall be placed against a wall of the test room or a vertical partition with an emissivity
between 0,9 and 1 at 25 °C having a length of at least 1 m on the side of the climate measuring point,
0,5 m on the opposite side and an height of at least 0,5 m more than the cabinet under testing at a
distance from the rear as specified in the instructions for use (see Figure 4).

5.3.3.2 Air movement
Air movement shall be provided. The air movement, shall be, as far as practicable, parallel to the plane
of the cabinet opening and to the longitudinal axis. The length of the cabinet is defined as the longest
horizontal dimension of the opening.
ISO 22041:2019(E)
Air velocity shall be measured in a vertical line through the climate measuring point with the cabinet in
operation and with the doors or drawers closed. The air velocity at one third, two thirds, three thirds of
the overall height of the cabinet shall be between 0,1 m/s and 0,2 m/s.
The direction of air flow shall be such that the air enters the cabinet when the door(s) is (are) open. For
refrigerated cabinets with multiple doors, 50 % or more of the doors shall open into the direction of
the air.
5.3.3.3 Loading the cabinet
5.3.3.3.1 General
The cabinet shall be loaded with test packages (see 5.3.2.4 and 5.3.2.8) and M-packages (see 5.3.2.5) up
to half the load limit, as illustrated in Figures 5 to 8.
Test packages with a mass of 1 000 g and 500 g shall be used.
To complete the loading, test packages of the following sizes (height × width × length) shall be used as
fillers:
— 25 mm × 100 mm × 200 mm
— 37,5 mm × 100 mm × 100 mm
— 25 mm × 100 mm × 100 mm
— 25 mm × 50 mm × 100 mm
The test packages shall be arranged so as to form an even level.
Each refrigerated shelf area shall be loaded with test packages arranged in such a way that they form
rows with a length of 200 mm by the depth of the cabinet shelf or drawer base or container. In case this
condition is not possible due to the size of the shelf or drawer base or container, evenly distributed rows
as close as possible to 200 mm shall be used.
A clearance of 25 mm ± 5 mm shall be left between package rows. If the clearance is limited by
construction, the packages adjacent to the side walls shall be loaded to the shelf extremity (see
Figures 5, 6 and 7).
Otherwise the clearance of the extreme package close to the walls shall be as close as possible to 25 mm.

It is permitted to use partitions with a thickness of approximately 25 mm to position the packages on
condition that they have minimal effect on normal airflow and minimal thermal conduction.
Lengthways, any remaining spaces shall be filled with test packages depth-wise and width-wise,
any remaining spaces of less than 25 mm wide shall be filled with wooden vertical dividers, placed
approximately midway along the space between two M-packages. A support system not influencing the
temperature distribution inside the cabinet may be used to support the test packages or the fillers.
In case the required clearance of 25 mm ± 5 mm between package rows cannot be maintained, special
shelves and support systems, not influencing the loading pattern and the temperature distribution
inside the cabinet may be used for this test purpose only. The special shelves shall not be considered for
the calculation of the net volume as in 6.1.
5.3.3.3.2 Loading heights
The loading height of the refrigerated shelves shall be as follows:
a) For refrigerated storage cabinets with drawers, the loading height shall be equal to half of the
+25
height defined by the load limit line of the drawer, with a tolerance of mm (see Figure 7). In the
