Pipes and connections to moving or resiliently mounted parts shall be arranged so as not to foul or transmit
harmful vibrations to other parts. All other pipes and connections shall be securely anchored and have
sufficient free length and/or vibration eliminators to prevent failure due to fatigue. Where necessary, pipes
and valves shall be adequately thermally insulated.
5.2.1.3 Lids
Lids shall be condensate-free at the climate class specified by the manufacturer.
When any lids provided to ensure an air seal to the refrigerated space are closed, there shall be no undue
leakage of ambient air into the interior (see 6.2.1). The lids shall not open of their own accord.
The gasket shall be made from a material whose characteristics are compatible with the operating conditions
(especially temperatures). If the fastening device is mechanical, a stop or other means shall be provided to
prevent the gasket from being excessively deformed.
5.2.1.4 Joints and seams
All construction joints and seams within the net volume shall prevent the accumulation of potentially
contaminating substances. All construction joints and seams within the net volume shall permit the easy
removal of any deposits of potentially contaminating substances.
5.2.2 Materials
5.2.2.1 General
The materials shall be durable and shall not favour the development of mould or emit odours. Under normal
conditions of use, materials in contact with foodstuffs shall be resistant to moisture and shall neither be
toxic nor contaminate them.
5.2.2.2 Corrosion resistance
Metal parts, used in the construction of cabinets, shall have resistance to corrosion appropriate to their
location and function.
5.2.2.3 Thermal insulation
The thermal insulation shall be efficient and permanently fixed. In particular, the insulating material shall
not be subject to shrinkage and shall not allow, under normal working conditions, an accumulation of
moisture.
ISO/DIS 22043:2024(en)
Suitable means shall be used to prevent deterioration of the thermal insulation by the ingress of moisture.
Where the insulation space is vented to the inside, it shall be ensured that particles of the insulation material
cannot escape into the foodstuff display compartment.
For fibrous insulation materials, it shall not be possible to insert a rigid probe of 1 mm diameter through any
aperture which allows access to the insulating material, the probe being applied with negligible force.
5.2.3 Refrigerating system
5.2.3.1 Design and construction
The design and construction of all parts of the refrigerating system subject to internal pressure shall take
into account the maximum working pressure to which they are subjected when the ice cream freezer is
in operation or at rest. The maximum ambient temperature during transit shall be taken into account. All
refrigerant containing components shall be in accordance with ISO 5149-2:2014.
5.2.3.2 Condensation
There shall be suitable means to prevent water condensing on cold surfaces of the ice cream freezer and its
parts and from harmfully affecting the operation of the refrigerating system or its controls.
5.2.3.3 System protection
For ice-cream freezers, the refrigerating system shall suffer no damage if any lid in the cooler is left open
while the ice cream freezer is operating in an ambient temperature corresponding to the climate class (see
Table 1) for which the cooler is intended. When the lid is kept open under normal operating conditions (for
example, during product loading) or is left open accidentally, any automatic motor overload protective
device may come into operation.
5.2.3.4 Refrigerant
When deciding on the refrigerant for the system, attention shall be given to the possible hazards associated
with the use of certain refrigerants and heat-transfer media due to their toxicity, flammability, etc. Guidance
on this point is available in ISO 5149-2:2014.
5.2.4 Electrical components
5.2.4.1 General
Electrical components shall be in accordance with IEC 60335-1:2020 and IEC 60335-2-89:2019.
5.2.4.2 Temperature display
The ice-cream freezer shall incorporate a temperature display instrument showing the air temperature in
the refrigerated display ice-cream freezer, at the load line, to provide an indication of the operation and
functioning of the refrigerating equipment and information on its operating state.
NOTE As a rule, measured air temperature is not identical with pre-packed ice-cream temperature in an ice-
cream freezer.
5.2.4.3 Temperature-measuring instrument
Suitable temperature-measuring instruments shall be used, i.e. those that fulfill the following requirements:
— the unit symbol (°C) shall be inscribed or displayed on the temperature-measuring instrument;
— the range of measurement shall be at least from −40 °C to + 40 °C;

ISO/DIS 22043:2024(en)
— the scale division or smallest numerical increment shall be less than or equal to 1 °C;
— the maximum errors shall be 2 K over the total measuring range;
— the time constant t of the sensor shall be equal to or less than 20 min.
When temperature-measuring instruments are employed in ice-cream freezers:
— one temperature-measuring instrument shall be employed for each ice-cream freezer with its own
refrigerating circuit.
5.2.4.4 Temperature sensor location
The temperature sensor location shall be readily accessible to enable on-site testing for the correct indication
of temperature and replacement of the temperature measuring instrument on-site in service.
The temperature sensor of a thermometer is considered to be “readily accessible” if it is reached directly for
examination. It is necessary to remove the access panel(s) to carry out replacement.
NOTE 1 The positioning of the temperature sensor in a guide tube is also considered to be “readily accessible” if the
sensor is introduced into and removed from the guide tube without a tool.
Wherever possible, the mounting method shall not supply heat to, or withdraw heat from the temperature
sensor. The temperature sensor shall be protected against heat radiation from the external ambient.
NOTE 2 For electronic controllers, it is possible to display a calculated temperature.
NOTE 3 For recording and display of temperatures, one or two temperature sensors are used. The temperature
sensor is the same as those used for controlling the refrigeration. An alarm is activated in case of error. This option is
not in accordance with the requirements of EN 12830.
5.2.5 Operating characteristics
5.2.5.1 Water vapour condensation
The performance of the ice-cream freezer shall not be impaired by water vapour condensation. The amount
of water vapour condensation shall be verified according to the conditions and test methods specified in
6.3.6.4.
5.2.5.2 Energy consumption
The energy consumption shall be stated by the manufacturer. The total energy consumption (TEC) shall be
measured and calculated according to the conditions and the test methods specified in 6.3.6.6.3.
5.2.5.3 Specific energy consumption
The ice-cream freezer specific energy consumption (SEC) as ratio between TEC and equivalent volume
(TEC/V ) shall be stated by the manufacturer. This value shall be used to compare the energy efficiency
eq
between different ice-cream freezers.
6 Tests
6.1 General
When the characteristics of an ice-cream freezer are to be verified, all the tests and inspections shall be
applied to one and the same ice-cream freezer. These tests and inspections may also be made individually
for the study of a particular characteristic.
Table 2 lists the tests and inspections that shall be carried out. Ice-cream freezers shall comply with the
requirements specified in this part of the document using the appropriate test method.

6.2 Tests outside test room
6.2.1 General
The tests which may be carried out outside the test room deal with the inspection of construction
characteristics, physical dimensions and the absence of odour and taste.
6.2.2 Seal test for lids
The effectiveness of lids provided to ensure a seal shall be tested as follows (with the ice-cream freezer not
running). Insert a strip of paper 50 mm wide, 0,08 mm thick and of a suitable length at any point of the seal.
With the lid closed normally on it the strip of paper shall not slide freely.
NOTE 1 Attention is drawn to the fact that some ice-cream freezers having lids are fitted with decompression
valves which allow air to penetrate for a short period of time so that any drop in pressure created inside the ice-cream
freezer is compensated. No test is required for such valves.
NOTE 2 The most unfavourable points can be found by inspecting the contact of the seal with the ice cream freezer
closed and lighted from the inside.
6.2.3 Test on durability of lid
6.2.3.1 General
The purpose of these tests, carried out using the following procedures, is to check the durability of the lids. The
ambient temperature shall be between +16 °C and +32 °C. The refrigerating appliance shall be switched off.
6.2.3.2 Opening sequence
The lids shall be pulled out to within 15 mm to 20 mm of their fully open position (Figure 1).
6.2.3.3 Closing sequence
The lids shall be closed as in normal use from within 15 mm to 20 mm of their fully closed position (Figure 1).

ISO/DIS 22043:2024(en)
Key
A opening course

Figure 1 — Durability of lid
The number of cycles per minute shall be between 5 and 10. Each lid shall withstand 30 000 opening and
closing operations without deterioration which could be prejudicial to the air-tightness of the lid sealing. All
the lids shall be present on the cabinet when tested.
6.2.4 Linear dimensions, areas and volumes
Measurements shall be made with the ice-cream freezer not in operation but situated in a place where
the temperature is maintained between 16 °C and 30 °C. If the ice cream freezer includes jacks or other
components for adjustment of height (i.e. castor or wheel), the height defined shall be the minimum height
necessary at installation of the ice cream freezer.
When measuring the net volume, parts necessary for the proper functioning of the ice-cream freezer shall
be fitted as intended and the volume representing the space occupied by these parts deducted (see 6.2.5).
6.2.5 Net volume calculation
The net volume (V ) shall be calculated as the sum of the individual volumes obtained within the load limit
N
lines, excluding any basket(s).
Each of the individual volumes shall be expressed in litres, to two decimal places. The net volume shall be
rounded to the nearest decimal place.
6.3 Tests inside test room
6.3.1 General
The tests which are carried out inside the test room measure the following characteristics:
— temperature;
— water vapour condensation;
ISO/DIS 22043:2024(en)
— electrical energy consumption.
General test conditions are defined, which are common for all tests carried out inside the test room. These
conditions concern the test room, the test and M-packages, and the measuring instruments.
6.3.2 Test room conditions
6.3.2.1 Design, walls, floor and radiant heat
The test room shall be a parallelepiped space in which two of the opposite side walls, referred to as the
discharge technical side wall and the return technical side wall, are designed to create an even, horizontal
air flow within the test room. By convention, the distance separating these two technical side walls is
referred to as the “length” of the test room.
The minimum useful dimensions (length, width, height) of the test room shall be dependent on the overall
dimensions (length, depth, height) of the ice-cream freezer to be tested.
The ceiling and the two non-technical side walls of the room shall be thermally insulated and shall be
equipped with an inner metal skin.
A minimum insulation level equivalent to 60 mm of rigid polyurethane foam (λ = 0,03 W/m °C) should be
used for the building of a new test room.
The floor shall be made of concrete or of thermally equivalent material and/or shall be sufficiently insulated
to ensure that external climatic conditions do not affect the floor temperature.
Lighting shall be installed to maintain (600 ± 100) lx measured at a height of 1 m above the floor level and
shall be lit continuously during the test period. The emission spectrum of that lighting device within the
infrared field shall not include peaks of a value of more than 500 W/5 nm/lm.
The walls, ceilings and any partitions of rooms intended for the testing of the ice-cream freezer shall be
painted in light grey (for example, NCS 2706-G90Y or RAL 7032) with an emissivity between 0,9 and 1 at 25 °C.
6.3.2.2 Thermal and air flow characteristics
An experimental evaluation of the test-room performances shall be carried out at a minimum of once per year
— with test room empty and with lighting switched on,
— in a test room at ambient temperature of 25 °C and 60 % RH,
— measuring the velocity, temperature and relative humidity of the air at different points within two
vertical planes parallel to the technical side walls and 600 mm away from the technical side walls, and
— with the climate measuring point located at the geometrical centre of the test room during the evaluation.
These measuring points shall form a two-dimensional grid in which the step is a maximum of 500 mm in the
horizontal and vertical directions. The peripheral line of points shall be located at a maximum of 500 mm
from the other two side walls, floor and ceiling.
A three-dimensional grid inside the test room shall be investigated when obstacles/irregularities projected
into the room of more than 1 m surface area facing the discharge technical side wall exist along the walls.
The mean horizontal air velocity measured during 1 min with a maximal interval of 5 s at each of the points
defined above shall lie between 0,1 m/s and 0,2 m/s.
Air temperature measured at each of the points defined above shall not deviate from the rated temperature
of the test-room climate class by more than 2 °C.
The test room shall be capable of maintaining values of humidity within ±5 units of the relative humidity
percentage figures of the rated humidity of the test room temperature class at the specified measuring points.

ISO/DIS 22043:2024(en)
Surface temperature of walls, ceiling and floor shall be measured in proximity to the points which constitute
the peripheral line of the grid defined above. These surface temperatures shall remain within a tolerance of
±2 °C in relation to the air temperature measured at the nearest point of the grid.
6.3.2.3 Climate classes
Tests shall be carried out in one of the climate classes according to Table 3.
During the test, the test room shall be capable of maintaining values of temperature and humidity within
±1 °C of the temperature and ±5 units of the relative humidity percentage figures at the specified climate
measuring point(s) (see 6.3.5.3).
Table 3 — Test room climate classes
Test room climate Minimum temperature and Maximum temperature and
class range relative humidity relative humidity
A +16 °C, 80 % 30 °C, 55 %
B +16 °C, 80 % 35 °C, 75 %
C +16 °C, 80 % 40 °C, 40 %
6.3.3 Test packages and life-time
6.3.3.1 General
When tests are carried out, test packages in the form of rigid parallelepipeds shall be used; the size and
mass of the test packages, including their packaging, shall be as specified in Table 4.
The tolerances for new test packages shall be:
— ±2 mm for linear dimensions 25 mm to 50 mm,
— ±4 mm for linear dimensions 100 mm to 200 mm, and
— ±2 % for mass.
Table 4 — Dimensions and mass of test packages
Dimensions Mass

The following packages may be used as fillers to complete the cabinet loading: 500
25 × 100 × 200
Due to the frequency of use and to the loading pressure, the packages could change in dimensions and weight.
Test packages shall be checked annually for conformity with the following life-time tolerances. When a test
package is found to exceed one of the following tolerances, it shall be replaced:
a) Loss of mass: −5 %.
b) On the wrapper: visible hole.
c) Change in linear dimensions:
1) ±4 mm for dimensions 25 mm and 50 mm;
2) ±8 mm for dimensions 100 mm
