Requirements on  Minimum Energy Performance Standard, Energy Efficiency 
Indication , and Inspection for Microwave Ovens  (Draft)  
 
Subject : Announcement for the Requirements on Minimum Energy Performance 
Standard , Energy Efficiency Indication , and Inspection of  Microwave Ovens  (Draft)  
 
Legal Basis : Paragraph 4, Article 14 of the Energy Administration  Act 
Announcement s:： 
1. The microwave ovens stated in this Announcement refer to those meeting the definition 
of microwave ovens  in CNS 60705  and promulgated by the Bureau of Standards, 
Metrology and Inspection (BSMI) of the Ministry of Economic Affairs (MOEA) as the 
products requirin g inspections. However, this Announcement and the Requirements do 
not apply to the microwave ovens  of the following conditions:  
(1) Microwave ovens with d iameter of load ≤200mm , or height of load ≤120mm ; 
(2) Rated power  input＞3300W . 
2. The testing of microwave  ovens  and the calculation thereof shall comply with the 
following requirements:  
(1). The output  power  (watt, W)  of microwave ovens  shall be tested in accordance 
with CNS 60705. The measured value of the o utput power  of microwave ovens  
rounded off to the nearest whole  number  shall be greater than  or equal to  95% of 
the rated  value of products.  
(2). The energy efficiency of microwave ovens  shall be tested and calculated in 
accordance with CNS 60705 . The measured value of the energy efficiency 
rounded off to the nearest whole number, as well as the rated  value, shall not be 
lower than the Minimal Energy Performance Standard (MEPS) of microwave  
ovens  (see Table 1), and  the measured value shall be greater than or equal to  95% 
of the rated  value of products.  
(3). The standby power of microwave ovens shall be tested and calculated in 
accordance with CNS 62301. The measured value of the standby power rounded 
off to the second decimal place, as well as the rated  value , shall not be higher than 
the MEPS of Microwave  ovens  (see Tabl e ), and the measured value shall not be 
higher than the rated  value.  
3. The rated  output  power , the rated  standby power , and the energy efficiency  shall be 
marked on  the bodies  or the smallest package s of the m icrowave ovens . 
4. The Central Competent Authority may conduct annual product sampling in accordance 
with the Guidelines for Energy Efficiency Labeling Inspection and Energy Efficiency 
Sampling of Designated Energy Using Equipment and Devices while conducting the 
energy effi ciency inspection. The model and  the quantity of  the testing sample s shall be 
designated by the Central Competent Authority, and the manufacturers shall deliver the 
product samples to the designated testing laboratories within the designated period . 
For the products not complying with  the requirements in Item 2, the Central Competent 
Authority shall request the related manufacturers to re -submit the samples for re -testing. 
The quantity of the re-tested samples shall be twice  the sampling quantity of the pro ducts 
of the same model . All the incurred cost s associated with the re -testing shall be borne by 
the manufacturers.  If the manufacture r fails to  conduct  the sampling or the  re-testing or fails to  meet the 
energy efficiency requirements  completely in the re -testing , Article s 21 and 24 of the 
Energy Administration Act  shall apply .
