 Amendment to Legal Inspection Re quirements of Drinking water 
suppliers 
 
By the Bureau of Standards, Metrology and Inspection (BSMI), Ministry of Economic 
Affairs (M.O.E.A.)  
Introduction: Drinking water suppliers (hereinafter referred as "the commodities") have been subject to 
mandatory inspection under the Commodity Insp ection Act by the Bureau of Standards 
Metrology and Inspection (BSMI) since 1 May 1990. To enhance consumer protection and 
promote efficiency of energy use, the BSMI proposes to adopt the latest version of inspection 
standards for the commodities. 
In addition to the safety and energy efficien cy requirements for the commodities, the BSMI 
proposes to require marking of presence conditions  of hazardous substances to inform users 
the conditions of 6 chemical substances in such  products. Such markings shall be made in 
accordance with Section 5 "Marking of Presen ce" of CNS 15663 on the body, packages, 
stickers or the instruction books of the comm odities. For those who utilize website as a means 
to announce "the presence conditions of the r estricted substances of the commodities," the 
website address shall be clearly stated on the bod y, packages, stickers or the instruction books 
of the commodities. 
The conformity assessment procedures for products subject to this notified measure remain the 
same, i.e. Registration of Products Certifica tion (RPC) or Type-approved Batch Inspection 
(TABI). 
 
Proposed date of implementation: 
1 January 2018 
 
Description of Goods  Inspection Standards C.C.C. Code (the first 
6 digits are the same as 
HS Code)(Reference)

250V AC, including those 
with/charged with a AC to DC 
adapter) 1. CNS 60335-1 (2014), 
CNS 60335-2-15 (2014), 
CNS 3910 (2016) Section 5 "Temperature 
of supplying water", Section 8.3 "Water storage capacity", S ection 10 "The 24 
hours energy consumption E
24" and 
Section 13 "Marking" 
2. CNS 13783-1 (2013) or 
CNS 13803 (2003) 
3. CNS 15663 (2013) Section 5 “Marking of 
Presence” 8418.69.90.00.9A

Locations to apply for Registration of Product Certification: The BSMI or its branches. 
 
Time required for Registration of Product Certification: 
14 working days. (This period does not include the time for corrective actions by the applicant 
due to deficiencies in the documents or sampl es. Extra 7 working days may be required for 
additional tests.) 
 
Related requirements: 
1. The revised inspection standards of the comm odities listed above will come into force on 2 
 the date of announcement and the current insp ection standards will become invalid from 1 
January 2018. The applicable inspection sch emes, conformity assessment modules of RPC 
and duration of certificates for the co mmodities above will remain unchanged. 
2. 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 comm odities shall also clearly mark the website 
address on the body, packages, stickers, or th e 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. 
3. Processing of applications: 
(1) Replacement: 
Before 31 December 2017, the certificate hol ders shall apply to the BSMI or its 
branches for replacement of their certificates by preparing type-test reports based on the 
revised inspection standards, technical documents as well as the 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 expiration date of the replaced certificates will be the same as 
that of the original certificates. Certificat es that are not replaced before 31 December 
2017 will be rescinded based on Paragraph 1, Article 16 of the “Regulations Governing 
Type Approval of Commodities” or Para graph 9, Article 42 of the “Commodity 
Inspection Act.” 
(2) New application or Extension: 
From the date of announcement, applicants sh all apply for certificate(s) according to the 
revised inspection standards by preparing the required type-test reports, technical 
documents as well as documents indicating th e 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 Subs tances Marking.” The validity period of 
certificate will be 3 years. The certificates will be valid till 31 December 2017 if the 
application is made based on the old inspection standards. 
4. 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 “t he presence conditions of the restricted 
substance” (e.g., RoHS or RoHS(XX,XX)). 
(2) The identification number shall be placed belo w or right next to the graphic symbol and 
“the presence conditions of the restricted s ubstance” 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 th at are not easily altered, and the content 
shall be in a clearly identifiable and i ndelible form affixed permanently to the 
commodity. 
(4) For RPC scheme, the examples of the Comm odity Inspection Mark are listed below: 
 
 
3 
  
  
(5) For TABI scheme, the examples of the Comm odity 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 referen ce 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. 
5. The C.C.C. Code listed in the table is used fo r reference only. The commodity listed in the 
table shall still complete the inspection proce dures before entering into the market even

of Finance or Bureau of Foreign Trade, Ministry of Economic Affairs. 
6. 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. 
7. Sections 8.3 and 10 of CNS 3910 are not a pplicable to instantaneous drinking water
