Ice-cream freezers - Classification, requirements and test conditions
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
Diese Norm definiert die Klassifizierung von geschlossenen horizontalen Speiseeis Gefriermaschinen und legt die Anforderungen und Prüfverfahren für Speiseeis Gefriermaschinen fest. Diese Geräte 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. Diese Norm gilt ausschließlich für eingebaute Kälteanlagen. Diese Norm gilt nicht für Kühlmöbel mit getrennt aufgestellter und indirekter Kälteanlage. Speiseeis Gefriermaschinen, die von dieser Norm abgedeckt werden, sollten über einen Nettoinhalt 600 l verfügen, mit Ausnahme von Speiseeis-Gefriermaschinen mit Glasdeckel, bei denen das Verhältnis Nettoinhalt/TDA 0,35 m betragen sollte.
Congélateurs pour crèmes glacées - Classification, exigences et conditions d'essai
Le but de la présente Norme européenne est de définir la classification des congélateurs pour crèmes glacées horizontaux fermés et de spécifier les exigences et méthodes d'essai. Ces appareils sont différents des congélateurs disponibles dans les 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. La présente Norme européenne est applicable uniquement aux systèmes de réfrigération intégrés. La présente Norme européenne n'est pas applicable aux armoires à système de fluide frigorigène incorporé ou à distance. Il convient que les congélateurs pour crèmes glacées relevant du domaine d'application de la présente norme aient un volume utile inférieur ou égal à 600 l ; il convient également que les congélateurs pour crèmes glacées munis de couvercles transparents aient un rapport volume utile/surface totale d'exposition (TDA) supérieur ou égal à 0,35 m.
Zamrzovalniki za sladoled - Razvrstitev, zahteve in preskusni pogoji
Namen tega evropskega standarda je opredeliti razvrstitev za vodoravno zaprte zamrzovalnike za sladoled ter določiti njihove zahteve in preskusne metode. Te naprave so drugačne od zamrzovalnikov v supermarketih, ker delujejo na statično hlajenje s površinskim izparilnikom (brez izparilnega ventilatorja) in se uporabljajo izrecno za shranjevanje in razstavljanje pakiranega sladoleda. Ta standard se uporablja samo za vgrajeni tip hladilnih sistemov. Ta standard se ne uporablja za oddaljene in sekundarne tipe sistemov omar. Zamrzovalniki za sladoled v okviru tega standarda naj bi imeli neto prostornino ≤ 600 l in samo zamrzovalniki za sladoled s prosojnim pokrovom naj bi imeli neto prostornino/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
contaminatin
