28、ral conditions of 7.1 of EN 203-1:2005. When tested in accordance with 7.101, the efficiency shall not be less than 50 %. 7.4.2 Temperature limits Addition: For this test, the pasta cooker is filled with water to its nominal level. 7.8.1 Stability and mechanical safety Addition: The basket is filled
29、 with the maximum nominal load and in the worst conditions. 7.8.101 Lack of heat bearing fluid Remove the heat bearing fluid and ignite the gas. When the safety devices shut down, it is checked that the surface temperature of the outside case does not exceed the ambient temperature by more than 80 K
30、. Furthermore, there shall be no deformation of the inside of the pasta cooker nor the outside of the case. 7.101 Rational use of energy At the ambient temperature of 20 C, the appliance is supplied with the reference gas giving the highest nominal heat input.
