1Proposal for amendment to the legal inspection requirements for 
uninterruptible power systems (UPS) products 
By the Bureau of Standards, Metrology and Inspec tion (BSMI), Ministry of Economic Affairs  
 
Background: 
Up to the present time, the uninterruptible power  systems (UPS) products ha ve to be subject to 
mandatory inspection in accordance with CNS 13438 (2006), CNS 1433 6-1 (2010), CNS 14843-1 
(2004), CNS 14843-2 (2004) and CNS 14757-2 (2003). In or der to enhance protec tion of consumers, 
the BSMI will adopt the revised electromagnetic  compatibility (EMC) standard CNS 14757-2 (2010) 
(harmonized with IEC 62040-2 j2005) and the electrical safety standards CNS 14843-1 (2004) and 
CNS 14843-2 (2004) for uninterruptible pow er systems (UPS) from March 1, 2013. 
 
Proposed date of implementation:   
‧March 1, 2013

Remarksj 1. CNS 14843-1 (2004) “Uninterr uptible power systems (UPS) ÑPart 1 : General and 
safety requirements for UP S used in operator access areas’’. (harmonized with IEC 
62040-1-1) 
 2. CNS 14843-2 (2004) “Uninterruptible power systems (UPS) ÑPart 1 : General and 
safety requirements for UPS used in restri cted access location’’. (harmonized with IEC 
62040-1-2) 
 3. CNS 14757-2 (2010) “Uninterruptible power systems (UPS) - Part 2: Electromagnetic 
compatibility (EMC) requirements”.  (harmonized with IEC 62040-2 j2005)  2The conformity assessment procedures for the inspection schemes are as follows: 
 
1. Registration of Product Certification (RPC) Scheme(Module II+ III) 
Under this procedure, domestic manufacturers or  importers must have th eir products type-tested 
in advance (Module II) before applying for re gistration of their products. Manufacturers or 
importers will also be required to ensure by declaration that all products made at their 
manufacturing facilities are in c onformity with the prototypes submitted for type test at Module 
II stage, and the declaration procedure is called Module III (conformity-to-type declaration). The 
conformity-to-type declaration shall be drawn up by the manufacturer or the authorized local 
representative, declaring that the products ma ss-produced will comply with the prototype as 
described in the type-test report.  
Products will be allowed to use the Commodity Inspection Mark with th e letter “R” and the 
identification number given by the BSMI, after they are certified and registered with the BSMI. 
The application fee and annual fee for RPC are both NT$5,000(about US$170) for each 
certification, and the RPC certificat ions are valid for three years. If there are any serial products, 
the extra NT$3,000(about US$102) of application f ee is needed for every application in each 
certification. 
 
2. Type Approved Batch Inspection (TABI) Scheme 
Under this scheme, the manufacturer or importe r shall have their products type-tested by the 
BSMI or designated testing laborat ories recognized by the BSMI, and then file an application for 
Type Approval with the BSMI. 
After manufacturers or importers obtain type-approval cert ificates, they are required to file an 
application for inspection with the BSMI before  their products are to be released from the 
production premises or arrive at the port of entr y. The BSMI will then review the application and 
accompanying documents according to the simplified procedures. The application fee for a Type 
Approval is NT$3500, and the Type Approval ce rtificates are valid for three years. 
 
Related requirements : 
1. From March 1, 2013, all such products which confor m to the revised inspection standards are eligible to 
apply for Registration of Product Certification (RPC) or Type-approved Batch Inspection (TABI)  from 
BSMI after this announcement. 
2. For those UPS products which have been certified befo re date of implementation, the transient measures 
are as follows: 
(1) These RPC or TABI certificates can still be used until their expired dates. 
(2) These certificate holders can still apply for adding serial model(s) registration according to current 
requirements before February 28, 2013. 
(3) These certificate holders can apply for the extension of validity of their certificates according to 
current requirements if the expired dates of these cer tificates fall before February 28, 2013, and their 
terms of validity are 3 years starting from the respective re-issue date; but if the expiration dates fall 
after March 1, 2013, these certificates should be handled in accordance with the provisions of the 
revised requirements. 
3. The inspection for all such products against st andard CNS 14757-2 will contain the electromagnetic 
susceptibility (EMS) testing.
