1 Proposal for adding the measurement of radiated dis turbance above 
1GHz and conducted disturbance at telecommunication  ports of CNS 
13438 to implement commodity inspection  
 
By the Bureau of Standards, Metrology and Inspectio n (BSMI), Ministry of Economic Affairs 
 
Background: 
Information Technology Equipment (ITE), multimedia equipment (which is tested as ITE) and similar 
products (HS: Chapter 84& 85) are subject to mandat ory inspection and shall comply with CNS 13438. 
The test items regarding the radiated disturbance a bove 1 GHz and conducted disturbance at 
telecommunication ports are not performed currently . In order to ensure protection of consumer, the 
BSMI intends to implement these two additional test  items of CNS 13438 beginning from October 1, 
2010. (CNS 13438: Information technology equipment - Radio disturbance Characteristics - limits and 
methods of measurement, as amended on June 1, 2006,  is harmonized with CISPR 22: 2005.04). 
 
Proposed date of implementation:   
October 1, 2010 
 
Products (HS/CCCN codes) covered and their applicab le inspection standards: 
Information technology equipment, multimedia equipm ent and similar products (HS: Chapter 84& 85) 
that are already announced to be subject to mandato ry inspection 
 
Related requirements:  
1.  Starting from October 1, 2010, the above-mentioned regulated products that are also required to 
comply with the requirements concerning radiated di sturbance above 1GHz and conducted 
disturbance at telecommunication ports of CNS 13438  (hereinafter as the legal inspection items).  
2.  The above-mentioned testing items are applicable to  products that have the internal emission 
sources utilizing highest frequency more than (incl uding) 108MHz and / or telecommunication 
ports such as Information Technology Equipment (ITE ), multimedia equipment and similar 
equipment that are tested to comply with CNS 13438.  
3.  Starting from the implementation date, products cov ered in this notice shall comply with the 
requirements of radiated disturbance above 1GHz, an d conducted disturbance at 
telecommunication ports in CNS 13438 when the appli cation for the Registration of Product 
Certification (RPC) or Type Approval (TA) certifica te is submitted to the BSMI. The BSMI will 
accept such applications complying with the above-m entioned testing items starting from the date 
of adoption of the notice. When the BSMI completes the review procedure and approves the 
application, a certificate will be issued and the a pplicable inspection standard column will be 
additionally stated “complete 2006 version.” 
4.  For those products that have been certified before the date of implementation, the certificates that 
are issued without implementation of the above-ment ioned testing items will remain valid until 
the date of expiration, provided that the products,  including the main model, are not modified. For 
products that the additional testing above 1GHz and /or conducted disturbance at 
telecommunication ports are required to be performe d, the certificates may be used until the 
expiry date and the certificate holders may not app ly for extension of validity of that certificate. 
For products to which the additional testing above 1GHz and conducted disturbance at 
telecommunication ports are not applicable, the cer tificate holders may apply for extension of 
validity of the certificate. 
5.  For product certificates that are issued without im plementation of the above-mentioned testing 
items, application for adding series models are acc eptable before the date of implementation. Such 
certificates may be used until the expiry date and the certificate holders may not apply for 
extension of validity of that certificate. If the m ain model and series models of a certificate are 
tested and comply with the above-mentioned testing items, the certificate holder may apply for a 
new certificate. The term of validity of the new ce rtificate will be 3 years and the applicable  2 inspection standard column will be additionally sta ted “complete 2006 version.” 
6.  When applying for adding series models that intend to comply with the above-mentioned testing 
items, all the existing main model and series model s of the certificate shall be tested and comply 
with the same requirements. A new certificate will be issued at the same time for such 
applications. 
7.  Starting from the date of implementation, for produ cts to which the above-mentioned testing items 
are applicable and the applicable inspection scheme  is Declaration of Conformity, the obligatory 
inspection applicant shall have their products test ed to comply with the complete test requirements, 
and re-declare the conformity (re-issue the declara tion of conformity) according to the relevant 
regulations before putting the product onto the mar ket.
