Communication from Switzerland
The following communication, dated 14 May 2002, has been received from the Permanent
Mission of Switzerland.
_______________
1. (a) Does your government have mandatory technical requirements for
electromagnetic interference of Information Technology equipment?  If so, please
identify.
Yes. The mandatory requirements are based on recommendation SN EN55022 (emission),
and where applicable SN EN 61000-3-2 and SN EN 61000-3-3.
(b) Are these requirements harmonized with CISPR 22?  If not, please explain the
current requirements.
Yes. The Norm SN EN 55022 is harmonized with CISPR 22.
2. (a) Does your government have mandatory technical requirements for
electromagnetic immunity of Information Technology equipment?  If so, please identify.
Yes. The mandatory requirements are based on recommendation SN EN 55024 (immunity).
(b) Are these requirements harmonized with CISPR 24?  If not, please explain the
current requirements.
Yes. The Norm SN EN 55024 is harmonized with CISPR 24.
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?
The possible procedures are the following :
a) Internal production control procedure;
b) Internal production control procedure plus specific apparatus tests;
c) Technical construction file procedure;
d) Full quality assurance procedure;G/IT/SPEC/Q4/4

- Information-Technology only: above mentioned procedure a)
- Receiver only: procedures mentioned above in points a), c) and d)- Transceivers and transmitters complying with officially designated technical
standards: procedures mentione d above in points b), c), and d)
- Transceivers and transmitters not complying or only partially complying with
officially designated technical standards: procedures mentioned above in points c),
and d)
- For fixed line telecommunications terminal equipment, the following procedures can
be selected: procedures mentioned above in points a), c), and d).
(b) May suppliers perform these procedures (e.g. testing, declaration of conformity),
or must third parties perform these procedures?
The supplier may perform the declaration of conformity. The testing is performed by third
parties (equipment manufacturer or accredited lab).
(c) What international guidelines or standards, if any, are those procedures based
on?  If not, what guidelines or standards are they based on ?
The guideline for the procedure is based on the Decree on Telecommunications Equipment
(OIT; RS 784.101.2), which transposes the European Community Directive CE/99/05.
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, howfrequent?  And please identify the nature of the complaint/problem.
Yes. We didn’t have a statistic on it.
Approved information technology products were put on the market without having been
accordingly modified so that they  comply with a successful  approval testing.
