Ice-cream freezers - Classification, requirements and test conditions (ISO 22043:2020)
The scope of this European Standard is to define the classification for horizontal closed ice-cream freezers and to specify their requirements and test methods. These appliances are different to supermarket segment freezers, as they work with static air cooling, with a skin evaporator (no evaporator fan) and are used specifically for the storage and display of pre-packed ice-cream. This standard is only applicable to integral type refrigeration systems. This standard is not applicable to remote and secondary system type cabinets. Ice-cream freezers within this standard should have a net volume ≤ 600 l and only for transparent lid ice cream freezers they should have a Net Volume/TDA ≥ 0,35 m.
Speiseeis-Gefriermaschinen - Klassifikation, Anforderungen und Prüfbedingungen (ISO 22043:2020)
Dieses Dokument legt die Klassifizierung von geschlossenen horizontalen Speiseeis-Gefriermaschinen mit Produktzugang von oben über (einen) durchsichtige(n) oder massive(n) Deckel und deren Anforderungen und Prüfverfahren fest.
Die in diesem Dokument definierten Speiseeis-Gefriermaschinen unterscheiden sich von Gefriermaschinen für den Supermarktbereich, da sie mit statischer Luftkühlung mit Außenwandverdampfer (ohne Verdampferventilator) betrieben und eigens für die Lagerung und die Ausstellung von vorverpacktem Speiseeis verwendet werden.
Dieses Dokument ist ausschließlich anzuwenden für Systeme mit integriertem Verflüssigungssatz. Es ist nicht anzuwenden für Möbel mit getrennt aufgestelltem Verflüssigungssatz oder für indirekte Systeme. Die in diesem Dokument definierten Speiseeis-Gefriermaschinen sollen über ein Nettovolumen von ≤ 600 l verfügen. Nur für Speiseeis-Gefriermaschinen mit durchsichtigem Deckel ist ein Nettovolumen/TDA ≥ 0,35 m vorgesehen.
Congélateurs pour crèmes glacées - Classification, exigences et conditions d'essai (ISO 22043:2020)
Le présent document spécifie la classification des congélateurs pour crèmes glacées horizontaux fermés avec accès au produit par le haut via un(des) couvercle(s) transparent ou solide et il spécifie les exigences et méthodes d'essai.
Les congélateurs pour crèmes glacées définit dans le présent document sont différents de ceux des supermarchés, parce qu'ils fonctionnent par refroidissement d'air statique, avec un évaporateur à surface (pas de ventilateur d'évaporateur) et qu'ils sont spécifiquement utilisés pour l'entreposage et l'exposition de crèmes glacées préemballées.
Le présent document est applicable uniquement aux systèmes de réfrigération intégrés. Il n'est pas applicable aux armoires à système de fluide frigorigène incorporé ou à distance. Les congélateurs pour crèmes glacées définis dans le présent document sont préus pour avoir un volume utile ≤600 l. Pour les congélateurs pour crèmes glacées seulement munis de couvercles transparents, ils sont prévus pour avoir un rapport volume utile/TDA ≥ 0,35 m.

5.2.1 Construction
5.2.1.1 Strength and rigidity
The ice-cream freezer and its parts shall be constructed with adequate strength and rigidity for normal
conditions of handling, transport and use. Attention shall be given to the following:
a) interior fittings shall be sufficiently strong for the duty required;
b) where sliding shelves, baskets or trays are fitted they shall retain their shape and ease of movement
when fully loaded;
c) any fitments which are provided with stops to prevent accidental removal shall be self-supporting
when fully loaded and withdrawn to the limit of the stops.
5.2.1.2 Pipes and connections
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.
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

DRAFT INTERNATIONAL STANDARD ISO/DIS 22043:2019(E)
Ice-cream freezers — Classification, requirements and test
conditions
1 Scope
The scope of this Standard is to define the classification for horizontal closed ice-cream freezer with
access of the product from the top via transparent or solid lid(s) and to specify their requirements and
test methods.
These appliances are different to supermarket segment freezers, as they work with static air cooling,
with a skin evaporator (no evaporator fan) and are used specifically for the storage and display of
pre-packed ice-cream. This standard is only applicable to integral type refrigeration systems. This
standard is not applicable to remote and secondary system type cabinets. Ice-cream freezers within
this standard should have a net volume ≤ 600 l and only for transparent lid ice cream freezers they
should have a net volume/TDA ≥ 0,35 m.

5.2 Requirements
5.2.1 Construction
5.2.1.1 Strength and rigidity
The ice-cream freezer and its parts shall be constructed with adequate strength and rigidity for normal
conditions of handling, transport and use and attention shall be given to the following:
a) interior fittings shall be sufficiently strong for the duty required;
b) where sliding shelves, baskets or trays are fitted they shall retain their shape and ease of movement
when fully loaded;
c) any fitments which are provided with stops to prevent accidental removal shall be self- supporting
when fully loaded and withdrawn to the limit of the stops.
5.2.1.2 Pipes and connections
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.

ISO/DIS 22043:2019(E)
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.
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.
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.
5.2.4 Electrical components
5.2.4.1 General
Electrical components shall be in accordance with EN 60335-2-89 and EN 60335-1.
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.

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.
NOTE 1 The temperature sensor of a thermometer is considered to be “readily accessible” if it is reached
directly for examination. It is necessary to remove access panel(s) to carry out replacement.
NOTE 2 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.
