The measurement setup shall correspond to Annex B. 5 Energy efficiency 5.1 Test methods 5.1.1 General The following tests are required to enable the values of elecQ , Qcorand AEC to be calculated using the formulas described in 5.2 for a chosen

42、tapping pattern as defined in Annex A. Losses resulting during idling are not taken into account. 5.1.2 Static efficiency This test shall measure the static loss of the appliance Plossat nominal load Pnomunder steady state conditions. If the appliance has a power selector, the selector should be adj

43、usted to the highest value. If the appliance has an independent flow control, it shall be adjusted to achieve the value stated in the manufacturers installation instructions, or where this is not stated, it shall be set to the highest value. If the appliance has a temperature control, the selector s

44、hall be adjusted to the highest value. For the purpose of this test result is independent from the water inlet temperature; therefore this test can be carried out with a cold water inlet temperature in the range of 10 to 25C. The inlet water temperature and flow rate must be such that the appliance

45、is caused to operate at full power continuously. The value of Pnomis the power consumption of the appliance measured after a minimum of 30 minutes of operation under full load conditions. The value of Plossis the sum of all internal power losses (product of current and voltage losses between the ter

46、minals and the heating elements) of the appliance measured after a minimum of 30 minutes of operation under full load conditions. For instantaneous water heaters with semiconductor power switches (e.g Triacs) the voltage across the semiconductor power terminals is subtracted from the measured voltag

47、e losses, if the semiconductor power switches are thermally connected to the water pipe. In this case, the heat developed by the semiconductor power switches is transferred to useful energy to heat up the water. The static efficiency is calculated from the formula: nom lossstaticnomPPP= where Pnomno

The test method assumes the power consumption of the appliance during the start-up period is equal to the power consumed in steady state conditions of the appliance for the specific draw-off i. If the appliance has a power selector, the selector should be adjusted to the highest value. If th
