SURVEY ON EMC/EMI
Replies to the Survey
Communication from Japan
The following communication, dated 30 May 2002, has been received from the Permanent
Mission of Japan.
_______________
1. (a) Does your government have mandatory technical requirements for
electromagnetic interference of Information Technology equipment?  If so, please
identify.
Yes. Electrical Appliance and Material Safety Law provides for mandatory technical
requirements related to electromagnetic interference for some electrical products based on the
document, WT/MIN(96)/16. However, the Law doesn't cover most IT products including the
products/components under HS headings 8471, 8517, 8544 and 9027.
(b) Are these requirements harmonized with CISPR 22?  If not, please explain the
current requirements.
The technical requirements are harmonized to CISPR22.
2. (a) Does your government have mandatory technical requirements for
electromagnetic immunity of Information Technology equipment?  If so, please identify.
Electrical Appliance and Material Safety Law doesn't provide any technical requirement
related to electromagnetic immunity.
(b) Are these requirements harmonized with CISPR 24?  If not, please explain the
current requirements.
Not applicable.
3. (a) What conformity assessment procedure for electromagnetic compatibility
(EMC/EMI), which includes both interference and immunity, does your government
require for approval of information technology products?
Under the term of EMC, there are Electromagnetic Interference(EMI) and Immunity.G/IT/SPEC/Q4/11

i) EMI
- Mandatory Requirements
As for the products covered by Electrical Appliance and Material Safety
Law, of which supplier performs self-declaration and/or obtains certificate ofconformity assessment issued by third-party conformity assessment body and
puts the mark on the product.
- Voluntary Requirements
Voluntary Control Council for Interference by Information Technology
Equipment(VCCI) which is a non-governmental organization provides
conformity assessment procedure for all other information technologyproducts besides some items which are subject to the law.
ii) Immunity
There is no conformity assessment procedure for immunity under Electrical
Appliance and Material Safety Law and the VCCI.
(b) May suppliers perform these procedures (e.g. testing, declaration of conformity),
or must third parties perform these procedures?
i) EMI
- Mandatory Requirements
Supplier's self-declaration and/or third-party conformity assessment. It
depends on the product, which is specified according to Electrical Applianceand Material Safety Law.
- Voluntary Requirements
In case of VCCI, it is self-declaration of suppliers. Testing must beperformed by VCCI registered laboratory.
ii) Immunity
There is no requirement or standards regarding procedures for testing and declaration
of conformity.  It is up to supplier's judgment.
(c) What international guidelines or standards, if any, are those procedures based
on?  If not, what guidelines or standards are they based on ?
i) EMI
- Mandatory Requirements
ISO based
- Voluntary Requirements
Technical and testing requirements are harmonized to CISPR 22. Declaration
of conformity is harmonized to VCCI Agreement. VCCI Agreement requires
its member companies to have their products testing performed by VCCI
registered site then to submit the conformity verification report.  Products
where conformity is verified can be indicated with a "VCCI label/mark".G/IT/SPEC/Q4/11

ii) Immunity
There is no conformity assessment procedure for immunity under Electrical
Appliance and Material Safety Law and the VCCI.
4. Has your regulatory authority received any complaint or had any problems regarding
the EMC/EMI aspects of the approved information technology products?  If yes, how
frequent?  And please identify the nature of the complaint/problem.
We have not received any complaint and problems regarding the EMC/EMI aspects of the
ITA products/components.
