 Proposal for Amendment to Legal Inspection R equirements  of Ventilators/Exhaust 
Hoods  
 
By the Bureau of Standards, Metrology and Inspection  (BSMI), Ministry of Economic Affairs  
 
Introduction:  
In response to the concerns raised by consumer s for the performance of kitchen ventilators to reduce 
cooking oil fume exposure resulted from our traditional cooking style , which is also significantly 
associated with lung cancer,  the Bureau of Standards, Metrology and Inspection (BSMI) proposes to 
revise the inspection standards for ventilators by adding the requirements for wind quantity as stated 
in Section 3.7 of CNS 3805, which specifies a minimum performance at 10 m3/min for single blade 
and 11.6 m3/min for double blades. Labelling of the wind quantity is not required. However, where 
wind quantity is labelled  on the body, packages, stickers or the user manual of the commodity , the test 
result shall not be lower than 95 percent  of the labe lled value.  
  
Proposed date of implementation:  1 January 2019

TABI Scheme  
 
Description of t he two kinds of conformity assessment procedures  
 
1. Registration of Product Certification ( RPC ) Scheme : Module s II + III  
Under th e II+III combination of modules used in 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 by declaratio n (Module III , conformity -to-type declaration ) that all products made at 
their manufacturing facilities or imported are in conformi ty with the prototypes submitted f or type -test at 
Module II stage . The conformity -to-type declaration shall be drawn up by the manufacturer or the 
authorized local representative, declaring that the mass -produced products comply with the prototype as in 
the type -test report.  
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 . 2 
 After manufact urers 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 
or arrive at the port of entry. The B SMI 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  days. (This period does not include the time for corrective actions by the applicant due to deficien cies 
in the docu ments or samples.  Extra  7 work days may be required if additional tests are required .) 
 
Related requirements : 
1. The other requirements, CNS 6 0335 -1 (2014), 60335 -2-3 (2015) and  13783 -1 (2013), were promulgated  
on 24 February 2017. A transitional period was given until  31 December  2018 to comply with the 
requirements . 
2. For the requirement of Section 5 “Marking of presence”  of CNS 15663, t he certificate holders  of the 
commodities  shall 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 clearly  mark  the website 
address on the body, package s, stickers,  or the instruction books of the commodities , instead . 
3. Processing of applications : 
(1) Replacement:  
Certificate holders  shall prepare  the type -test report based on  the updated  inspection standard s, technical 
documents, and  “Declaration of Conformity to Wind Quantity  for Ventilators/Exhaust Hoods” to apply 
to the BSMI or its branches for replacement of the certificate (s) before 31 December 2018 . 
(2) New a pplication  or Extension : 
From the date of announcement , applicant s shall apply to the BSMI or its branches by providing the 
following documents:  
- type-test report,  
- technical documents ,  
- “Declaration of Conformity of Wind Quantity  for Ventilators/Exhaust Hoods,”  
- documents indicating  the location of the “marking of presence, ” sample s of the “Marking of Presence ” 
(see Table 1 and Table 2) , and 
- “Declaration of the Presence Condition of the Restricted Substances Marking .” 
(3) A commodit y, which is  designed for small suites or integrated  in a system cabinet , and the width  of 
which is less than 65 cm, is waived from the requirement of  CNS 3805  (1989) Section 3.7 “ Wind 
Quantity. ” The “Declaration of Conformity to Wind Quantity  for V entilators/Exhaust Hoods”  is not 
required.  
4. The Commodity Inspection Mark : 
(1) The Commodity Inspection Mark sh all be printed by the certificate holder s. The identification number of 3 
 the Commodity Inspection Mark consists of  “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 to the right of the graphic symbol  and the presence 
conditions of the restricted substance  shall be i ndicated  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 permanently  to the  commodity . 
(4) For RPC scheme, the examples of the Commodity Inspection Mark  are listed below:  
 
 
 
 
 
(5) For TABI scheme , the examples of the Commodity Inspection Mark  are listed below:  
 
 
 
 
 
(6) “RoHS ” indicate s the content of restricted substance (s), other than exemption s stated in CNS 15663, 
does not exceed the reference percentage value of presence condition . 
“RoHS  (XX,XX) ” indicate s the content of restricted substance (s) (element  XX, element XX , …), other 
than exemption s stated in CNS 15663,  exceed s the reference percentage value of presence condition . 
The restricted substances: indicate s Pb, Cd, Hg, Cr+6, PBB, and PBDE.  
Example:  
 RoHS  (Pb): indicate s that the Pb percentage content in certain  parts  of the commodity  exceeds the 
reference percentage value of presence condition . 
 RoHS  (Cd, Cr+6, PBB): indicate s that the Cd, Cr+6, and PBB percentage content in certain  parts  of the 
commodity exceed the reference percentage value of presence condition  respectively.  
5. The C.C.C. Codes listed in the form are used for reference only. The commodities shall still comply with 
the requirements  before entering into the market, even though their C.C.C. Code s are identified differently 
by the Customs Administratio n, Ministry of  Finance or Bu reau of Foreign Trade, Ministry of Economic 
Affairs.  
6. This proposed announcement  of updated inspection standards will supersed e the previous ones . 
7. Commodities with combined type s or multifunction -products  shall comply with the respective inspection 
standards and the conformity assessment procedures of RPC  scheme .
