1- General conditions for testing:  
-  for refrigerating appliances with anti -condensation heaters that can be switched on and off by the 
end-user, the anti - condensation heaters shall be switched on and —  if adjustable —  set at 
maximum heating and included in the annual energy consumption (AE) as daily energy 
consumption (E daily); 
-  for refrigerating appliances with ambient controlled anti -condensation heaters, the ambient 
controlled electric anti - condensation heaters shall be switched off or otherwise disabled, where 
possible, during the measurement of energy consumption;  
-  for refrigerating appliances with dispensers that can be switched on and off by the end- user, the 
dispensers shall be switched on during the energy consumption test but not operating;  
-  for the measure ment of energy consumption, variable temperature compartments shal l operate at 
the lowest temper ature that can be set by the end- user to continuously maintain the temperature 
range, as set out in Table 2 , of the compartment type which has the lowest temper ature;  
-  for refrigerating appliances that can be connected to a network, the communication module shall 
be activated but there is no need to have a specific type of communication or data exchange or 
both during the energy consumption test. During the energy consumption test it has to be ensured 
that the unit is connected to a network;  
-    for the performance of chill compartments:  
(1) for a variable temperature compartment rated as a fresh food and/or chill 
compartment, the energy efficiency index (EEI) shal l be determined for each 
temperature condition and the highest value shall be applied;  
(2) a chill compartment shall be able to control its average temperature within a certain range without user -adjust - mend s of its control, this can be verified during the energy 
consumption  tests at 16 °C  and 32 °C  ambient temperature;  
 
-  for adjustable volume compartments, when the volumes of two compartments are adjustable 
relative to one another by the end- user, the ene rgy consumption and the volume shall be tested 
when the volume of the compartment with the higher target temperature is adjusted to its minimum 
volume;  
- the test voltage/frequency shall be 230V 50Hz.  
 
    
 
 15 2- Determination of the EEI:  
 
Energy efficiency index EEI, expressed in % and rounded to the first decimal place, 
calculated as:  
 
EEI = AE / SAE.  
 
3- Determination of the AE:  
 
For all refrigerating appliances the energy consumption AE shall be determined by testing at an 
ambient temperature of 16 °C and 32 °C.  
AE, expressed in kWh/a and rounded to two decimal places, shall be calculated as follows:  
 
AE = 365 × E daily /L + E aux 
 
            W ith: 
 
-  The load factor L = 0.9 for refrigerating appliances with only frozen compartments and L =  1.0 for 
all other appliances; and  
- With Edaily, expressed  in kWh/24h and rounded to three decimal places calculated from E T at an 
ambient temper ature of 16 °C ( E16) and at an ambient temper ature of 32 °C ( E32) as follows:  
  
E
daily=(𝐸𝐸16 ×𝑓𝑓)+(𝐸𝐸32 ×𝑓𝑓) 
Where:  
 
f is a weighting factor for the temperature in the rooms and is equal to 0. 5  
     -   E16 and  E32 are  derived by interpolation of the energy test at the target temperatures   
 
- Eaux, expressed in ( kWh/ year)  and rounded to three decimal places.  
 Eaux  is limited to the ambient controlled anti -condensation heater and is determined from the 
heater’s  power consumption at ambient temperature and humidity conditions, multiplied with the 
probability that this ambient temperature and humidity condition occurs a nd summed; this result is 
subsequently multiplied with a loss factor to account for heat leakage into the compartment and its 
subsequent removal by the refrigeration system.   
For all tests, should conduct at ambient temperatures of 16 °C and 32 °C. In addi tion, Relative 
Humidity at 60 to 70 % with mid- point 65% . It is the responsibility of the manufacturer to provide the 
temperature and humidity data to the laboratory to prepare the test report.  
 
       
  
 
 16 4- Determination of the standard annual energy consumption (SAE):  
 
For all refrigerating appliances SAE, expressed in kWh/a, and rounded to two decimal places, is 
calculated as follows:  
𝑆𝑆𝑆𝑆𝐸𝐸 =𝐶𝐶 × 𝐷𝐷 × �Ac𝑛𝑛
𝐶𝐶=1× 𝐵𝐵𝐵𝐵 × [𝑉𝑉𝐵𝐵/𝑉𝑉] × (𝑁𝑁𝐵𝐵 + 𝑉𝑉 × 𝑟𝑟𝐵𝐵 × 𝑀𝑀𝐵𝐵) 
                                                                  
       where  
-  c is the index number for a compartment type ranging from 1 to n, with n the total number of 
compartment types;  
- Vc, expressed in dm3 or liters  and rounded to the first decimal place is the compartment volume;  
- V, expressed in dm3 or  liters  and rounded to the nearest integer is the volume with  𝑉𝑉  ≤∑ Vc𝑛𝑛
𝑐𝑐=1 . 
- rc, Nc, M c  and c are modelling parameters specific to each compartment with values in Table 6 ; 
-  Ac, Bc  and D are the compensation factors with values as set out in Table 7 . 
When carrying out the calculations above, for the variable temperature compartments, the 
compartme nt type with the lowest target temperature for which it is declared suitable is chosen.

determined  as follows: 
—  if Vf / V ≤ 0,3 then 
      C = 1,3 + 0,87 × Vf / V ; 
—  else if 0,3 < Vf / V < 0,7 
then C = 1,87 - 1,0275 × Vf / 
V; 
—  else  C = 1,15 .
