24、 construction The type and surface conditions of materials likely to come into contact with food shall be such that they do not contaminate or spoil the food. In addition to the general requirements under intended conditions of use, the materials used for food zone and splash zone shall be: DIN EN 2

The junction between the lower parts and the vertical sides shall be constructed with a radius more than or equal to 3,5
27、mm (see Figure 1) or with two angles equal to 135 2. Dimensions in millimetres Figure 1 - Internal angles and corners An internal corner formed by the intersection of these planes shall have either two intersections with a minimum radius of 3,5 mm or with an angle of more than or equal to 135 and th
28、e third intersection shall have a minimum radius of 7 mm. The dimension between the two bends shall be equal to or greater than 7 mm (see Figure 2).

They shall preferably be made by welding or continuous bonding
30、. Screws, screw-heads and rivets shall not be used except where technically unavoidable. If screws are used, the screw thread shall not project by more than one and a half threads, if the screw-heads are apparent they shall comply with Figure 7. 5.1.3 Surface assembly Assembled surfaces are consider

Food Zone Figure 4 Assembly by continuous bonding and flush joint 5.1.4 Surface overlapping Assemblies may be made by the overlapping of sheet,
32、 in which case the assembled surfaces shall be joined to each other: either by a continuous weld: the upper surfaces shall overlap the lower surfaces in direction of liquid flow. The end of the overlapping and the corner shall be separated with a distance h more than or equal to 30 mm. The overlappi
33、ng shall not provide a horizontal projection of a depth greater than 1,5 mm (see Figure 5).

36、.3.1 Wall mounted or floor standing appliances 5.3.1.1 Non mobile appliances Appliances shall be: - either put on the ground with interposition of a continuous and tight seal, the instructions for installation specifying the jointing procedure; or - provide a height of at least 150 mm between the ho
37、rizontal base of the appliance and the ground. This distance may be reduced to 100 mm if the depth of the space to be cleaned is less than 650 mm. Those requirements are not applicable to appliances of which the mass is less than 18 kg or for appliances between 18 kg and 36 kg with handling means. I
38、f the appliance is fitted with feet, those shall be designed so as not to provide a dirt accumulation zone. Threads of feet screws or jacks shall not be exposed. The concentric clearance between the smooth part of the screw and the sheath shall be less than or equal to 1 mm. A distance greater than
39、or equal to 20 mm, when the screw jack is closed, shall be obtained between the lower part of the sheath and the ground. Where the supporting part of the adjustment screw is of a diameter greater than those of its cylinder part, the height of the supporting part shall be less than or equal to 7 mm a
40、nd the radius of the junction between the supporting part and the cylinder part shall be greater than 3,5 mm or have 2 junction angles of at least 135. If DIN EN 203-3:2009-10 EN 203-3:2009 (E) 9 the feet surface is greater than 1 dm, the feet surface shall be considered as put on the ground (with i
41、nterposition of a seal). 5.3.1.2 Mobile appliances Systems allowing mobility will be easily cleanable. If the appliance is fitted with castors, the design shall be such as to facilitate cleaning. In particular, the distance between the hoop and the screed shall be at least 6 mm. The finish of the sc
42、rew shall be flush. The hoop shall be smooth. The braking system shall be designed so as to avoid crevices. The careenage surface shall be reduced to the minimum. 5.3.2 Appliances put on a table If the appliance is fitted with feet requirements applicable to feet described in 5.3.1.1 shall be met. F

44、handling means. 5.3.3 Control panel The control panel shall be located in the non-food zone and be accessible for cleaning as required. The distance L between two control panel components shall be greater than or equal to: - 20 mm; - 12,5 mm if their height h is less than or equal to 8 mm. If the ab
45、ove requirements cannot be complied with, controls shall be protected by cap. Those configurations are described in Figure 8.
