Food processing machinery - Rotary rack ovens - Safety and hygiene requirements
This standard specifies safety and hygiene requirements for the design and manufacture of rotary rack ovens with one or more rotary racks.
These ovens are used in the food industry and shops (bakeries, pastry-making, etc.) for the batch baking of foodstuffs containing flour, water and other additives. This standard applies to ovens used only for food products except for those containing volatile flammable ingredients.
The control of the humidity of the air in the baking chamber is by the production and introduction of steam around normal atmospheric pressure.
The following machines are excluded:
- experimental and testing machines under development by the manufacturer;
- domestic appliances.
This standard covers the technical safety requirements for the installation, cleaning and maintenance of these machines as defined in 3.12 of EN 292-1:1991 and in the manufacturer's instruction handbook.
The significant hazards covered by this standard are mechanical (shearing, trapping, impact, loss of stability), electrical, thermal, ergonomic and those resulting from lack of hygiene. They are specifically listed in 4. Noise is not considered to be a significant hazard from rotary rack ovens. This does not mean that the manufacturer of the machine is absolved from reducing noise and making a noise declaration. Therefore a noise test code is proposed in Annex B.
The hazards from the use of gaseous fuel by gas appliances are not covered by this standard.
This standard applies only to machines manufactured after the date of issue of the standard.

Machines pour les produits alimentaires - Fours à chariot rotatif - Prescriptions relatives à la sécurité et l'hygiène
La présente norme spécifie les prescriptions de sécurité et d'hygiène relatives à la conception et à la fabrication
des fours à un ou plusieurs chariots rotatifs.
Ces fours sont utilisés dans l'industrie alimentaire et les commerces de l'alimentation (boulangeries, pâtisseries, etc.)
pour la cuisson non continue de produits alimentaires contenant de la farine, de l'eau et d'autres additifs. Cette norme
s'applique aux fours utilisés exclusivement pour des produits alimentaires, à l'exception de ceux qui contiennent
des ingrédients volatils inflammables.
La régulation de l'humidité de l'air dans la chambre de cuisson est obtenue par la production et l'introduction
de vapeur d'eau sous une pression très voisine de la pression atmosphérique normale.
Les machines suivantes sont exclues de la présente norme :
- machines expérimentales et d'essais en cours de mise au point par le fabricant ;
- appareils à usage domestique.
!La présente norme couvre les prescriptions techniques de sécurité relatives au transport, à l’installation,
au fonctionnement, au nettoyage et à la maintenance de ces machines (voir 5.2 et 5.3 de l’EN 12100-1:2003).
Le présent document traite de tous les phénomènes, situations et événements dangereux significatifs spécifiques
aux fours à chariot rotatif, lorsqu'ils sont utilisés normalement et dans des conditions de mauvaise utilisation
raisonnablement prévisibles par le fabricant (voir Article 4).
Le bruit n’est pas considéré comme un phénomène dangereux significatif. Ceci ne signifie pas que le fabricant de la
machine est dispensé de réduire le bruit et d'établir une déclaration de bruit. Par conséquent, un code d'essai
acoustique est donné en Annexe B."
Les risques dus à l'utilisation de combustibles gazeux dans des appareils à gaz ne sont pas couverts par cette norme.
!La présente norme n’est pas applicable aux fours à chariot rotatif fabriqués avant sa date de publication en tant

Stroji za predelavo hrane - Peči z vrtljivim vozičkom - Varnostne in higienske zahteve
Ta standard določa varnostne in higienske zahteve za načrtovanje in izdelavo peči z vrtljivim vozičkom z enim ali več vrtljivimi vozički. Te peči se uporabljajo v prehrambeni industriji in trgovinah (pekarne, izdelava peciv itd.) za serijsko peko živil, ki vsebujejo moko, vodo in ostale dodatke. Ta standard velja za pečice, ki se uporabljajo samo za živila, razen tistih, ki vsebujejo hlapne gorljive sestavine. Nadzor vlažnosti zraka v komori, v kateri se peče, je v proizvodnji in uvedbi pare pri normalnem atmosferskem pritisku. Izvzeti so naslednji stroji: - eksperimentalni in preskusni stroji, ki jih razvija proizvajalec; - gospodinjski aparati. Ta standard zajema tehnične zahteve glede varnosti za prevoz, namestitev, delovanje, čiščenje in vzdrževanje teh strojev (glej 5.2 in 5.3 EN ISO 12100-1:2003). Ta evropski standard obravnava vse velike nevarnosti, nevarne situacije in primere, ki se tičejo peči z vrtljivim vozičkom, kadar se uporabljajo, kot je predvideno, in pod pogoji napačne uporabe, ki jih razumno predvidi proizvajalec (glej Klavzulo 4). Hrup ne šteje kot velika nevarnost. To ne pomeni, da je proizvajalec oproščen zmanjševanja hrupa in priprave deklaracije o hrupu. Zato je preskusna koda hrupa podana v Dodatku B. Nevarnosti zaradi uporabe plinastega goriva v plinskih napravah niso zajete v tem standardu. Ta standard ne velja za pečice z vrtljivim vozičkom, ki so izdelane pred datumom objave v obliki EN.
