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.
