Affairs   
 
Introduction:  
In line with the energy policy, the BSMI require s that microwave ovens be subject to Section  6 
“General conditions for measurements ”, Section 8 “Determination of microwave power output ” 
and Section 9 “Efficiency ” of CNS 60705 : 2018 , and  CNS 62301 : 2017 .  
The measured efficiency and standby power  shall comply with the  Table of “MEPS for 
Microwave Ovens ” as stated in “Requirements on Minimum Energy Performance Standard, 
Energy Efficiency Indication, and  Inspection for Microwave Ovens ” to be adopted by the 
Bureau of Energy, which was notified as G/TBT/N/TPKM/456.  
The conformity assessment procedures for products subject to this notified measure remain the 
same, i.e. Registration of Produc ts Certification (RPC) or Type -Approved Batch Ins pection 
(TABI).  
 
Date of implementation:

Conformity assessment procedures : No change.  
 
Related requirements : 
1. Microwave ovens  powered by USB cord/port DC 5V and without a n AC to DC adaptor, 
only powered by and with power supply products for automotive cigar lighter, only 
powered by three -phase or only -batteries shall not be subject to legal inspection.  
2. The revised inspection standards of the commodities listed above will come into force  on 
the date of announcement and the current  inspection standards  will become in valid from 1  
Jan 2023. The applicable  inspection  schemes , conformity assessment modules  of RPC  and 
duration of certificates  for the commodities  above will remain  unchange d. 
3. National deviation:  
(1) The supply cords shall at least comply with CNS 15767 -1 “Plugs and socket -outlets for 
household and similar purposes − Part 1: General requirements .” 2 
 (2) Class 0 structure is not allowed.  
4. The certificate holders  of the commodities  shall  follow  the content stipulated in  Section 5 
“Marking of presence”  of CNS 15663  and clearly mark  “the presence condition  of the 
restricted substance s” on the body, package s, stickers , or the instruction books of the 
commodities . Those who utilize  website as a means to announce  “the presence condition  
of the restricted substance s” of the commodities  shall  also clearly  mark  the website 
address on the body, package s, stickers,  or the instruction books of the commodities . In 
that case, t he requ irement s of Section 5.3 of CNS 15663 are  not applicable to the position s 
of the markings.  
5. Processing of applications : 
(1) Replacement:  
Before 1 January  2023 , the certificate holders  shall  apply to the BSMI or its branches for 
replacement of their certificate s by preparing  type-test reports  and technical documents  
based on CNS 60705 and CNS 62301 . The expiration date of the replaced certificate s 
will be the same  as that of the original certificate s. Certificate s that are not  replace d 
before 1 January  2023  will be rescinded  based on Paragraph 1, Article 16 of the

(2) New a pplication  or Extension : 
From the date of announcement , applicant s shall  apply  for certificate (s) according to the 
revised  inspection standards  by prepar ing the required  type-test report s, technical 
documents  as well as documents indicat ing the location of the “marking of presence ,” 
sample s of the “Marking of P resence ” (see Table s 1 and 2) , and the “Declaration of the 
Presence Condition of the Restricted Substances Marking .” The validity period of 
certificate will be 3 years.  The certificate s will be valid ti ll 31 December  2022 if the 
application is made  based on  the current  inspection standard s. 
6. The Commodity  Inspection Mark : 
(1) The Commodity Inspection Mark sh all be printed by the certificate holder s. The 
identification number of the Commodity Inspection Mark consists of  “A Letter  (R or 
T),” “Designated  Code (5 digits )” and “th e presence conditions of the restricted 
substance” ( e.g. RoHS or RoHS(XX,XX)) . 
(2) The identification number shall be placed below or right next to  the graphic symbol  and 
“the presence conditions of the restricted substance”  shall be indicated  in the second 
row.  
(3) The size  of the Mark can be applied  proportionally  on a prominent location  of the 
commodit ies. The Mark shall use materials that are not easily altered, and the content 
shall be in a clearly identifiable and indelible form affixed perm anently to the 
commodity.  
(4) For RPC scheme, the examples of the Commodity Inspection Mark  are listed below:  
 
 
 
 
 
 
3 
 (5) For TABI scheme, the examples of the Commodity Inspection Mark  are listed below:  
 
 
 
 
 
 
(6) “RoHS” indicates “the content of restricted substance(s), other than exemptions stated 
in CNS 15663,  does not exceed  the reference percentage value of presence condition.  
“RoHS(XX,XX)” indicates the content of restricted substance(s) (element XX, element 
XX, …), other  than exemptions  stated in CNS 15663, exceeds the reference percentage 
value of presence condition.  
Restricted substances: Pb, Cd, Hg, Cr+6, PBB, and PBDE.  
Example s:  
 RoHS  (Pb) indicates that the percentage content of Pb in certain parts of the 
commodity exceeds the  reference percentage  value specified in Annex A to CNS 
15663.  
 RoHS  (Cd, Cr+6, PBB ) indicates that the percentage content of Cd, Cr+6, and PBB in 
certain parts of  the commodity exceeds the respective reference percentage value 
specified in Annex A to CNS  15663.  
7. The C.C.C. Code listed in the table is used for reference only. The commodity listed in the 
table shall  still complete th e inspection  procedures before entering into the market even 
though their C.C.C. Code is  identified differently by the Customs A dministration, Ministry 
of Finance or Bureau of Foreign Trade,  Ministry of Economic Affairs . 
8. The inspection standards of the products listed in the table shall be the version published in 
this announcement. If any updated version is available, the BSMI sha ll publish the
