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
