Requirements on Minimum Energy Performance Standard  and Energy 
Efficiency Rating  Labelling and Inspection of Electric R efrigerator s and 
Freezers  
Subject：Announcement for the Requirements on Minimum Energy Performance 
Standard and Energy Efficiency Rating Labelling and Inspection of 
Electric Refrigerator s and Freezers  
Basis： Paragraph 4, Article 14 of the Energy Management Act  
Announcement ： 
1. Domain ： The refrigerators and r efrigerator -freezers  denoted in this announcement are 
those meeting the definition in CNS 2062, and promulgated by the Bureau of 
Standards, Metrology and Inspection (BSMI) of the Ministry of Economic Affairs (MOEA) as products requiring inspection before marketing.  
2. Test Method ：CNS 2062  
3. Minimum Energy Performance S tandard (MEPS) ：The tested value of energy factor  
(EF) shall not be less than the standard value specified in the Table 1 (minimum 
energy performance standard requirements for electric refrigerators and freezers) and 
be more than 95% of the marked value on products.  
4. Labelling Scheme for Energy Efficiency Rating  
(1) Displayed label  minimum  size：180mm (long)× 120mm(width), its samples and 
specifications as follow ： 
   
 1    
 (2) Content of energy efficiency rating label  
(i) Product name (Electric refrigerators and f reezers ); 
(ii) Product model number;  
(iii) Total storage volume ( L); 
(iv) Energy factor (L/kWh /month);  
(v) Energy efficiency rating; 
The products shall be classified for energy efficiency rating based on the energy 
factor value shown in the following Table 2 and shall be marked onto the energy 
efficiency labelling.  
Annual power consumption is calculated at monthly power consumption multiplied by 12 months. The actual power consumption volume depends upon 
the condition of actual use;  
(vi) The year and announcement number of the Announcement containing the 
Criteria for Energy Efficiency Rating of  Electric refrigerators and freezers  used 
for this rating determination;  
(vii) Registration number for this rating ; 
(viii) Other text as designated by the Central Competent Authority . 
(3) Display or post the label  
While displaying or marketing the products, the dealer shall  display or post the energy 
efficiency rating label on the front of the products, and shall  not hide, destroy or adopt 
other means to render the label not recognizable by the consumers. While 
manufacturing or importing the products, the dealer shall display or attach the energy 
efficiency label  in/on the product instruction/manual, or place the label in a prominent 
area on the front of the products.  
(4) Energy efficiency rating  
After the aforementioned application has been approved by the Central Competent  
 2 Authority, the dealer may download the energy efficiency rating label from the 
management s ystem and start using the label.  
(5) Compliance inspection scheme  
In principle, the number of products first sampled and tested shall be decided based on 
the sales volume of the designated model number of  the previous year, and one 
sample shall be tested out of 4,000 units of such product model sold. If less than 4,000 
units were sold for that model number in the prior year, one sample shall be  tested. 
Nonetheless, the Central Competent Authority may change the sampling ratio based 
on actual needs.

Note：  
1. The refrigerators  and refrigerator -freezers  denoted in this a nnouncement are those 
meeting the definition in CNS 2062. 
2. The symbol V stands for the total adjusted volume. 
3. Total adjusted volume V(L) =  VR + K × V F 
VR (L): Inner volume of fresh -food storage compartment  
VF (L): Inner volume of frozen-  food storage compartment   
K : Adjustment factor for frozen- food storage compartment, two- star =1.56 ; super 
two-star =1.67 ; th ree-star and four -star =1.78  
4. Products with two or more frozen-  food storage compartments operating independently , 
the total adjusted volume shall be summed  up by the multiplier  of each compartment 
volume and adjustment factor, i.e. V(L) =V R + K 1 × V F1 + K2× V F2 + … 
5. Total adjusted volume and EF value are rounded off to one  decimal place.  
6. The tested EF value shall be not less than the standard value shown on the above table 
and be 95% or more of the product marked value.
