30、 use. The materials in contact with water, coffee and infusion shall not adversely affect the organoleptic properties of the coffee infusion. The components of closing and safety devices shall be made with materials not subject to corrosion, dilatation or deformation so to affect their working. ? EN
31、 13248:2002 (E) 7 4.2 Manufacturing requirements 4.2.1 Cleaning and maintenance The coffee maker shall be designed and constructed in such a way that maintenance is simple cleaning without using special instruments . Particular care shall be taken over the finish of inside surfaces so that cleaning
32、can be carried out thoroughly and easily. 4.2.2 Surfaces The surfaces of the coffee maker shall be smooth, continuous, uniform, without blisters or pits and without defects, cracks or cutting edges that may injure the user. 4.2.3 Base The base of the coffee maker, be it flat or otherwise, shall not
33、be convex in order not to affect its stability, even when placed in working conditions at the safety pressure (see Figure 2). When measured in accordance with Figure 3, the maximum concavity of a flat base shall not be more than 6 of the base diameter measured at room temperature. This requirement s
34、hall be checked in accordance with 5.6.1. NO Figure 2 Example of boiler base Dimensions in millimetres ? EN 13248:2002 (E) 8 006, 0 2 = C Rext Figure 3 Measurement of the base concavity 4.2.4 Handling devices The body of the coffee maker shall be equipped with a handle. The lid, if any, shall be equ
35、ipped with a knob. These handling devices shall be safe, resistant and durable. When it is submitted to the tests described in 5.3.1, the handle shall not suffer any breakage or permanent deformation and its fixing system to the body of the coffee maker shall not fail. The handle and the knob shall
36、be designed in such a way that their temperature, when measured according to 5.3.2, is not higher than the following values: a) metals55 C b) ceramic, glass and stone66 C c) plastics70 C d) wood89 C and in such a way that the coffee maker can be handled safely without the user coming into contact wi
37、th any parts of the coffee maker exceeding the maximum temperature described above. ? EN 13248:2002 (E) 9 4.2.5 Pouring system When tested in accordance with 5.2.2 the coffee infusion shall flow cleanly from the pouring system. Single drops can flow back on to the side wall of the coffee maker, but
38、there shall be no continuous dripping. 4.2.6 Percolator The minimum distance between the boiler internal base and the lower end of the percolator shall be 2 mm. The bottom of the percolator may be fixed or detachable and replaced by a reducing filter as defined in 3.1.10. 4.2.7 Filter The filter hol
39、es shall allow the passage of the coffee infusion from the percolator to the coffee delivery system by retaining the charge of coffee. 4.2.8 Reducing filter The holes of the reducing filter, if provided, shall allow the passage of water to the percolator. 4.2.9 Sealing system The sealing system shal
40、l be made using geometry and materials fit for assuring the tightness of the connection between the boiler and the coffee delivery system under the scheduled working conditions. The operation of the sealing system shall be checked after being tested in accordance with 5.6.1. After completion of this
41、 test the sealing system shall still be working perfectly. 4.2.10 Boiler The boiler may comprise a single element or an assembly of more elements. The boiler shape shall not compromise, in any way, the stability of the coffee maker. 4.2.11 Coffee delivery system The coffee delivery system shall allo
42、w the passage of the coffee infusion without injury to the user. The sealing system seat shall have features fit for assuring the grip of the filter and of the sealing system. 4.2.12 Lid The lid of the coffee infusion container, if any, can be fixed to the coffee infusion container or can be separat
43、e. If the lid is separate it shall not fall off when pouring the coffee infusion. 4.2.13 Coffee infusion container The coffee infusion container, if any, shall have a capacity greater than the produced volume Vpand it shall be checked in accordance with 5.2.1. 4.2.14 Working pressure When tested acc
44、ording to 5.4, the working pressure (Pn ) shall be between 50 kPa (0,5 bar) and 250 kPa (2,5 bar) . ? EN 13248:2002 (E) 10 4.2.15 Stability The handle and knob affixed to the coffee maker shall be simple to use and shall not affect the stability of the coffee maker. If the lid of the coffee infusion
45、 container is fixed to the coffee infusion container, the stability of the coffee maker shall not be compromised when the lid is open. The stability of the coffee maker without integral coffee infusion container as described in Figure 1 b shall not be compromised when placing the coffee cup under th
46、e coffee delivery system at the end of the delivery of the coffee infusion. These requirements shall be checked in accordance with 5.2.3. 4.2.16 Closing/opening system The coffee maker shall be designed in such a way to prevent the accidental and unintentional operation of the closing/opening system
47、. Moreover, the coffee maker shall be such that during its operation the closing/opening system can be blocked or prevented from opening only if the rules for correct and safe use of the coffee maker contained in the instructions for use are disregarded. 4.3 Safety device The coffee maker shall have
48、 a safety device (see 3.1.6). It shall be placed on the part occupied by the steam. The safety device shall assure that, during its use, the safety pressure value (Ps) is lower than 400 kPa. The safety device shall be designed so that during its operation the steam jet does not affect the stability
49、of the coffee maker, nor extinguish the flame, when heating the coffee maker on gas burner. These requirements shall be checked in accordance with 5.5. 4.4 Pressure strength 4.4.1 Deformation strength When tested in accordance to 5.6.1, the coffee maker shall not undergo any permanent deformation that can compromise its use and safety After the test, the conc
