in such a way that maintenance is
simple cleaning withoutusing special instruments .Particular care shall be taken over the finish of inside surfaces so that cleaning can be carried out thoroughly andeasily.4.2.2 SurfacesThe 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 BaseThe base of the coffee maker, be it flat or otherwise, shall not be convex in order not to affect its stability, evenwhen 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 ‰ ofthe base diameter measured at room temperature.This requirement shall be checked in accordance with 5.6.1.NOFigure 2 — Example of boiler baseDimensions in millimetresSIST EN 13248:2003

systemWhen tested in accordance with 5.2.2 the coffee infusion shall flow cleanly from the pouring system. Single dropscan flow back on to the side wall of the coffee maker, but there shall be no continuous dripping.4.2.6 PercolatorThe 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 FilterThe filter holes shall allow the passage of the coffee infusion from the percolator to the coffee delivery system byretaining the charge of coffee.4.2.8 Reducing filterThe holes of the reducing filter, if provided,
shall allow the passage of
water to the percolator.4.2.9 Sealing systemThe sealing system shall be made using geometry and materials fit for assuring the tightness of the connectionbetween 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 test the sealing system shall still be working perfectly.4.2.10 BoilerThe 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 systemThe coffee delivery system shall allow the passage of the coffee infusion without injury to the user. The sealingsystem seat shall have features fit for assuring the grip of the filter and of the sealing system.4.2.12 LidThe lid of the coffee infusion container, if any, can be fixed to the coffee infusion container or can be separate. Ifthe lid is separate it shall not fall off when pouring the coffee infusion.4.2.13 Coffee infusion containerThe coffee infusion container, if any, shall have a capacity greater than the produced volume Vp and it shall bechecked in accordance with 5.2.1.4.2.14 Working pressureWhen tested according to 5.4, the working pressure (Pn ) shall be between 50 kPa (0,5 bar) and 250 kPa (2,5 bar) .SIST EN 13248:2003

coffee cup under the coffee delivery system at the end of the delivery of the coffeeinfusion.These requirements shall be checked in accordance with 5.2.3.4.2.16 Closing/opening systemThe coffee maker shall be designed in such a way to prevent the accidental and unintentional operation of theclosing/opening system.Moreover, the coffee maker shall be such that during its operation the closing/opening system can be blocked orprevented from opening only if the rules for correct and safe use of the coffee maker contained in the instructionsfor use are disregarded.4.3 Safety deviceThe coffee maker shall have 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 of thecoffee 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 strength4.4.1 Deformation strengthWhen tested in accordance to 5.6.1, the coffee maker shall not undergo any permanent deformation that cancompromise its use and safetyAfter the test, the concavity of the base shall conform to 4.2.3.4.4.2 Destruction strengthWhen applying pressure, in accordance with 5.6.2, the coffee maker can undergo deformations, but it shall notpresent any breakage and/or stress.4.5 CoatingsInternal coatings in contact with water, coffee and coffee infusion, when tested in accordance with 5.7, shall notpresent, upon inspection, visible fissure, breakage, blister or crack.SI
