 Proposal for amendment to the legal inspection regulation for Electric 
Storage Drink Water Heaters  
 
By the Bureau of Standards, Metrology and Inspection  (BSMI), Ministry of Economic 
Affairs  (M.O.E.A. )  
 
Introduction:  
The Electric Storage Drink Water Heaters  (hereinafter referred as "the commodities") has been 
subject to mandatory inspection under the Commodity Inspection Act by the Bureau of 
Standards Metrology and Inspection (BSMI) since 1 January  1992. In line with the energy 
policy, the BSMI proposes to require that electric storage drink water heaters be subject to 
Sections 10.7 “ capacity of inner tank test” and 10.8 “ standardized standby loss of every 24 
hours E st,24 test” of CNS 12623 , where the measured  value ( Est,24) shall comply with that stated 
in “Requirements on Minimum Energy Performance Standard (MEPS) for electric storage 
tank boiling water heaters .” In addition , the BSMI will revise the Description of Goods of the 
commodities t o “Electric Storage Tank Boiling  Water Heaters”  according to CNS 12623.  
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 July 2021

Description of the two kinds of conformity assessment procedures  
 
1. Registration of Product Certification ( RPC ) Scheme：Module s II + IV or II + V or II 
+ VII  
For product subject to Modules II+IV , II+V , or II+VII procedures, not only the 
products shall be type -tested in advance (Module II) by the BSMI or BSMI -recognized 
testing laboratories, but the quality management systems of the production premises must 
be in conformity with Module IV (Full Quality Management System), Module V 
(Production Quality Management System) or Module VII (Factory  Inspection).  2 
 For Module IV and Module V , a registration certificate in accordance with the CNS 
12681 (ISO 9001) series of standards is required to be obtained from the BSMI, or 
certification bodies recognized by the BSMI. As for Module VII, a factory insp ection 
report issued by the BSMI or BSMI -recognized factory inspection bodies is needed in the 
same way.  
In addition, a declaration of conformity -to-type is also required to ensure that the 
mass -produced commodities are in conformity with that shown in the  type-test report for 
all the above three IV , V , VII modules.  
After being  certified and registered by the BSMI , products will be allowed to use the 
Commodity Inspection Mark with the letter ‘R’ and the identification number given by the 
BSMI. Additionally , these products can  clear  customs directly without any further 
inspection if not be ing sampled by RPC border check procedure s. The application fee and 
annual fee for RPC are both NT$5,000  (about US$170) for each certification, and the RPC 
certification is valid for 3 years. If there are any serial products, an extra NT$3,000  (about 
US$102) of application fee will be charged  for every application in each certification.  The 
fees for type testing vary by products and depend on the fee policies  of the testing 
laboratories.  
 
2. Type -approved Batch Inspection (TABI) Scheme  
Under this procedure, manufacturers or importers shall have their products 
type-tested by the BSMI or the designated testing laboratories recognized by the BSMI, 
and file an application for Type Approval to the BSMI or its branches.  
After manufacturers or importers obtain a type approval certificate, they are required 
to file an application for batch inspection to the BSMI each time before their products are 
released from the production premises o r arrive at the port of entry. The BSMI will then 
review the application and the related documents while additional samples may be 
required for further testing if it is deemed necessary.  
After the products have passed the inspection, they will be allowed to use the 
Commodity Inspection Mark with the letter ‘T’ and the identification number given by the 
BSMI. The application fee for a Type Approval is NT$3,500, and a Type Approval 
certificate is valid for 3 years. The fees for type testing vary by products and depend on the 
fee policies of the testing laboratories.  
*Further information on the two schemes can also be found on the BSMI web site: 
http://www.bsmi.gov.tw/wSite/ct?xItem=8673& ctNode=811&mp=2  
 
Locations  to apply for Registration of Product Certification:  
The BSMI  or its branch es. 
 
Time required for Registration of Product Certification:  
14 work ing days.  (This period does not include the time for corrective actions by the applicant 
due to deficiencies in the docu ments or samples.  Extra  7 work ing days may be required for 
additional tests .)
