17、N 203-3:2009 (E) 4 1 Scope This part 3 of EN 203 applies to all appliances covered by EN 203-1:2005 and related part 2. It has been written in order to specify the requirements concerning the hygiene aspects of large kitchen appliances using gaseous fuels, so as to eliminate or minimise the risk of
18、contagion, infection, illness or injury arising from the consumption of contaminated food. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest editio
19、n of the referenced document (including any amendments) applies. N/A 3 Definitions 3.1 food zone surface of the appliance in direct contact with food and/or from which food and/or other products may emanate, drip, diffuse and/or splash back onto the food 3.2 splash zone surface on which food may spl
20、ash or flow along under intended conditions of use and does not return onto the food or cooking chamber 3.3 non food zone any area other than those specified above 3.4 corrosion resistant material material resistant to normally occurring action of chemical or electrochemical nature; it includes food
21、 processing, cleaning and disinfection according to the instructions for use 3.5 non absorbent material material which, under intended conditions of use, does not retain substances with which it comes into contact so that it has no adverse influence on food 3.6 non toxic material material which does
22、 not produce or release substances injurious to health under intended conditions of use 4 Materials of 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
23、 under intended conditions of use, the materials used for food zone and splash zone shall be: BS EN 203-3:2009EN 203-3:2009 (E) 5 corrosion resistant; non toxic; non absorbent (except when technically or functionally unavoidable). Also the materials shall: not transfer undesirable odours, colours or
24、 taints to the food; not contaminate the food or have any adverse influence on the food. 5 Constructional requirements 5.1 Food zone 5.1.1 Angles and corners Internal angles and corners of the food zone shall be constructed in such a way as to be easily and properly cleaned. The junction between the
25、 lower parts and the vertical sides shall be constructed with a radius more than or equal to 3,5 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 i
26、ntersections with a minimum radius of 3,5 mm or with an angle of more than or equal to 135 and the 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). Dimensions in millimetres Figure 2 Intersection of two
27、 planes BS EN 203-3:2009EN 203-3:2009 (E) 6 The junction between the upper parts and vertical sides may be constructed with an angle of 90 without any particular requirement for the radius. 5.1.2 Connection of internal surfaces Assemblies shall be designed in such a way as to reduce projections, edg
28、es and recesses to a minimum. They shall preferably be made by welding or continuous bonding. 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 appa
29、rent they shall comply with Figure 7. 5.1.3 Surface assembly Assembled surfaces are considered joined: either by continuous weld (see Figure 3); or Food Zone Figure 3 Assembly by continuous weld by continuous bonding and flush joint (see Figure 4). Food Zone Figure 4 Assembly by continuous bonding a
30、nd flush joint 5.1.4 Surface overlapping Assemblies may be made by the overlapping of sheet, 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 an
31、d the corner shall be separated with a distance h more than or equal to 30 mm. The overlapping shall not provide a horizontal projection of a depth greater than 1,5 mm (see Figure 5).

32、 or by non welded assembly: when the overall thickness of the overlapping part joint is more than 1,5 mm, the upper part shall be chamfered in order to reduce the thickness d to less than or equal to 1,5 mm (see Figure 6).

33、203-3:2009EN 203-3:2009 (E) 8 5.2 Splash zone The splash zone shall be designed so as to avoid the accumulation of dirt in recesses. The allowed screws are given in Figure 7.

35、ying the jointing procedure; or - provide a height of at least 150 mm between the horizontal 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
36、 is less than 18 kg or for appliances between 18 kg and 36 kg with handling means. If 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 th
37、e screw and the sheath shall be less than or equal to 1 mm. A distance greater than 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 cy
38、linder part, the height of the supporting part shall be less than or equal to 7 mm and 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 BS EN 203-3:2009EN 203-3:2009 (E) 9 the feet surface is great
39、er than 1 dm, the feet surface shall be considered as put on the ground (with interposition 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 distan
40、ce between the hoop and the screed shall be at least 6 mm. The finish of the screw 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
41、 with feet requirements applicable to feet described in 5.3.1.1 shall be met. Furthermore the minimum height of the feet H is function of the distance of accessibility P given in Table 1: Table 1 Minimum height of feet P Hmm mm 650 75 650 150 Those requirements are not applicable to appliances of wh
42、ich the mass is less than 18 kg or for appliances between 18 kg and 36 kg with 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
43、: - 20 mm; - 12,5 mm if their height h is less than or equal to 8 mm. If the above requirements cannot be complied with, controls shall be protected by cap. Those configurations are described in Figure 8. The above requirements are not applicable if the control panel components are easily removable
44、and can be cleaned after removing.
