Communication from Switzerland
Addendum
The following communication, dated 10 September 2002, has been received from the
Permanent Mission of Switzerland.
_______________
In response to the question of the Australian delegation of 5 July 2002 in relation to the Swiss
response to the EMC/EMI G/IT/SPEC/Q4/4 questi onnaire of 22 March 2002 and as a result of recent
changes to the Swiss regulations having taken effect by 1 July 2002 Switzerland has revised the
response to the original questionnaire as follows:
3. (a) What conformity assessment procedure for electromagnetic compatibility
(EMC/EMI), which includes both interference and immunity, does your governmentrequire for approval of information technology products?
According to the Swiss Ordinance on electromagnetic compatibility, the following conformity
assessment procedures are applicable to all information technology products:
a)  Declaration of conformity drawn up by the manufacturer (self-certification);
b)  Technical file drawn up by the manufacturer which includes a technical report or
certificate issued by a competent assessment body if the manufacturer has not or
partially used harmonized standards as a base for the conformity assessment
procedure.
In relation to radio transmitters  and to teleco mmunications terminal equipment, the following
complementary conformity assessment procedures from the Swiss Ordinance on
telecommunication equipment apply:
a) Internal production control;
b) Internal production control plus specific apparatus tests;
c) Technical construction file (internal production control, specific apparatus tests and
examination of the file by a competent conformity assessment body);
d) Full quality assurance.G/IT/SPEC/Q4/4/Add.1

The choice of the correct procedure is the responsibility of the manufacturer.  It depends on
the following criteria:  type of equipment;  existence of harmonized technical standards
officially designated by the Swiss Federal Office of Communication (OFCOM) and their
application for the conformity assessment procedure by the manufacturer.
(b) May suppliers perform these procedures (e.g. testing, declaration of conformity),
or must third parties perform these procedures?
In the following answer, we assume that the supplier is the manufacturer of the equipment.
The above-mentioned procedures a) through f) are carried out by the manufacturer.  This also
includes any testing as required.  In relation to the procedures b), e) and f), the manufacturerneeds to consult notified bodies in relation to assuring proper compliance.  The establishment
of a declaration of conformity by the manufacturer under his own responsibility applies to all
of the above-mentioned procedures a) through f).
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 been involved in various instances of that nature.  However, no specific causes of
statistical relevance have been observed so far.
