1Proposal for amendment to the legal insp ection regulation for Electric Storage 
Tank Water Heaters 
 
By the Bureau of Standards, Metrology and Inspecti on (BSMI), Ministry of Economic Affairs (MOEA) 
 
Introduction: 
The Electric Storage Tank Water Heaters have be en subject to mandatory inspection under the 
Commodity Inspection Act by the Bu reau of Standards Metrology and Inspection (BSMI) since 1 
February 1972. Based on the original listed inspec tion standards [CNS 3765  (2005), IEC 60335-2-21 
(2004), CNS 13783-1(2004)], the BSMI will add the test terms an d methods which are Section 8.11 
“Capacity of inner tank” & 8.14 “Standardiz ed standby loss of every 24 hours, E st,24” of the standard 
CNS 11010 “Electric Storage Tank Water Heaters”  (promulgated on 27 December 2013). The 
“Standardized standby loss of every 24 hours, E st,24” must meet the requirem ents of Minimum Energy 
Performance Standard (MEPS) of Electric Storage Tank Water Heaters when those products will be 
imported or placed on the domes tic market after 1 October 2015.  The conformity assessment procedure 
for those products will be under the Registration of Product Certification (RPC) Scheme or Type-Approved 
Batch Inspection (TABI) Scheme.

  2The two kinds of conformity assessment schemes for the Electric Storage Tank Water Heaters are as  
follows: 
 
1. Registration of Product Certification (RPC) Scheme (Module II + IV or II+V or II+VII ) 
Under this scheme, domestic manufacturers or importers  must have their products type-tested in advance 
(Module II) by the BSMI or BSMI-recognized testing laboratories before applying for registration of 
their products. Manufacturers or importers will also be  required to ensure that those products whether 
made at their manufacturing facilities or imported are in conformity with the prototypes submitted for 
type test at Module II stage. In addition, the qua lity management systems of the production premises 
must be in comformity with Module IV (full qualit y assurance), Module V (production quality assurance) 
or Module VII(factory inspection). For Module IV a nd Module V , they are required to get certificateion 
in accordance with the CNS 12680 (ISO 9000) series of standards. As for Module VII, it is required to 
obtain a factory inspection report issued by the BSMI or BSMI-recognized factory inspection bodies. A declaration of conformity is also required to en sure the quality of the mass-produced  commodities are 
in conformity with that shown in the type-test report. 
Products will be allowed to use the Commodity Inspec tion Mark with the letter ‘R’ and the identification 
number given by the BSMI, after they are certified and registered with the BSMI. These products can 
then pass through customs directly without any further inspection if not be sampled by RPC border check 
procedure. The application fee and annual fee for RPC are both NT$5,000(about US$170) for each 
certification, and the RPC certifications are valid for three years. If there are any serial products, the extra 
NT$3,000(about US$102) of application fee is need ed for every application in each certification. 
The fees for type testing vary by products and de pend on the fee schedule of the testing laboratories. 
 
2. Type-approved Batch Inspection (TABI) Scheme 
Under this scheme, manufacturers or importers shall have their products type-tested by the BSMI or 
BSMI-recognized testing laboratories, and then file an application for type approval with the BSMI or its 
branches. 
After manufacturers or importers have obtained a type -approval certificate, they are still required to file 
an application for batch inspection with the BSMI ea ch time before their products arrive at the port of 
entry. The BSMI will then perform inspection with  simplified procedures. Additional samples may be 
required for further testing if it is deemed necessary. The application fee for a type approval is NT$3,500, 
and a type approval certificate is generally valid for three years. 
The fees for type testing vary by products and de pend on the fee schedule of the testing laboratories. 
Further information about the two schemes is also available on the BSMI web site at 
http://www.bsmi.gov.tw/wSite/ct?xItem=8673&ctNode=811&mp=2
 
 
Locations to apply for Type Testing: 
The BSMI or BSMI-recognized testing laboratories. 
 Locations to apply for Registration of Product Certification: 
The BSMI or its branch offices. 
 Time required for Registration of Product Certification: 
Fourteen working days. (This period does not include th e time for corrective actions by the applicant due to 
deficiencies in the documents or samples; another seven  working days may be required if additional tests are 
required) 
 
Related requirements: 
1.
 Aiming to enhance the efficiency of energy utili zation, we intend to promote the regulated energy 
efficiency requirements, so as to reduce electricity lo ss. The Section 8.11 & 8.14 of the revised standard 
CNS 11010 “Electric Storage Tank Wate r Heaters” (promulgated on 27 December 2013) listed in the table 
will be effective as of 1 October 2015. In addition, as of  the date that this notice is promulgated, the BSMI 
will accept such applications for t hose heaters to comply with “the Standardized standby loss of every  324 hours ”, which is tested under th e requirements of CNS 1 1010 and have to meet the requirement of the 
Minimum Energy Performance Standard (MEPS) of Electric Storage Water Heaters.  
2. If the RPC certificates of those products are issued before 1 October 2015, but they do not comply with the 
energy efficiency requirements against the section 8. 11 & 8.14 of the revised standard CNS 11010, then 
these RPC certificates will be only valid till 30 September 2015.  
3. The inspection standards shall be the version as listed in this public notice. When the applicable standards 
are revised or amended, the date of applying these re vised or amended standards for inspection shall be 
further decided and announced by the BSMI.
