 Proposal for Amendments to the Legal Inspection Requirements for 
Microwave Ovens 
 
By the Bureau of Standards, Metrology and Inspection (BSMI), Ministry of Economic 
Affairs  
 
Introduction: 
In line with the energy policy, the BSMI proposes to require 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 Products Certification (RPC) or Type-Approved Batch Inspection 
(TABI). 
 
Proposed date of implementation: 
1 Jan 2023

CNS 60335-2-25: 2016  
2. CNS 13803: 2003 
3. CNS 15663: 2013 Section 5 “Marking of Presence” 
4. For products under the scope of “Requirements on Minimum 
Energy Performance Standard, Energy Efficiency Indication, 
and Inspection for Microwave Ovens”:  
CNS 60705: 2018 Section 6 “General conditions for 
measurements”, Section 8 “Determination of microwave 
power output” and Section 9 “Efficiency”, and CNS 62301: 
2017. The measured efficiency and standby power shall 
comply with the Table of “MEPS for Microwave Ovens.” 8516.10.00.00.9C 
 
Conformity assessment procedures: No change. 
 
Related requirements: 
1. Microwave ovens powered by USB cord/port DC 5V and without an 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 invalid from 1 
Jan 2023. The applicable inspection schemes, conformity assessment modules of RPC and 
duration of certificates for the commodities above will remain unchanged. 
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 substances” on the body, packages, stickers, or the instruction books of the 
commodities. Those who utilize website as a means to announce “the presence condition 
of the restricted substances” of the commodities shall also clearly mark the website 
address on the body, packages, stickers, or the instruction books of the commodities. In 
that case, the requirements of Section 5.3 of CNS 15663 are not applicable to the positions 
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 certificates by preparing type-test reports and technical documents 
based on CNS 60705 and CNS 62301. The expiration date of the replaced certificates 
will be the same as that of the original certificates. Certificates that are not replaced 
before 1 January 2023 will be rescinded based on Paragraph 1, Article 16 of the 
“Regulations Governing Type Approval of Commodities” or Paragraph 9, Article 42 of 
the “Commodity Inspection Act.” 
(2) New application or Extension: 
From the date of announcement, applicants shall apply for certificate(s) according to the 
revised inspection standards by preparing the required type-test reports, technical 
documents as well as documents indicating the location of the “marking of presence,” 
samples of the “Marking of Presence” (see Tables 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 certificates will be valid till 31 December 2022 if the 
application is made based on the current inspection standards. 
6. The Commodity Inspection Mark: 
(1) The Commodity Inspection Mark shall be printed by the certificate holders. The 
identification number of the Commodity Inspection Mark consists of “A Letter (R or 
T),” “Designated Code (5 digits)” and “the 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 
commodities. The Mark shall use materials that are not easily altered, and the content 
shall be in a clearly identifiable and indelible form affixed permanently 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. 
Examples:  
 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 the inspection procedures before entering into the market even 
though their C.C.C. Code is identified differently by the Customs Administration, 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 shall publish the 
implementation date of the updated version in further announcement. 
9. Commodities with combined features or multifunctional products shall comply with the 
respective inspection standards and conformity assessment procedures of RPC scheme.
