20、during testing to the tolerance detailed in Table 1. Any deviations from these tolerances will result an invalid test. All testing should be performed at the rated power for the appliance (based on a rating at 230V/400V as applicable). 4.4 Test Setup Replacement: The appliance shall be fixed in acco

21、rdance with the installation instructions except that the shower hose shall not be connected. Products covered by this standard are only to be tested to the XS load pattern detailed in Annex A, Table A.1. The measurement setup shall correspond to Annex B. 5 Energy efficiency This clause of Part 1 is

22、 applicable except as follows. 5.1 Test method 5.1.1 General Addition It is allowable to decrease the time between draw offs in order to accelerate the load pattern detailed in Annex A, as long as it can be demonstrated that results are not affected.

23、.1.1.101 Set Points The appliance shall be set to achieve minimum flow (f) as specified in Annex A for all efficiency tests. This can be increased if the appliance is unable to operate continuously and the flow rate used recorded. This flow rate is used for all individual draw offs within the prescr

24、ibed load pattern. 5.1.2 Static efficiency Addition The loss adjustment for semiconductor power switches of open outlet electronic instantaneous water heaters is not applicable for this type of appliance. 5.1.3 Start up losses Replacement The start up loss istartQ is the total energy in kWh that is

25、consumed by the appliance between energizing the heatingelements and the delivery of useable water temperature for each specific draw off i. istartQ is measured using a Wh meter for the duration between the point at which the heater elements are energised and when the outlet water has achieved the m
