Ing. et al,
I looked into this some time ago and determined that educational devices do
not have an exemption under the EMC Directive, I quote it here:
Quoting ---
The maximum electromagnetic disturbance generated by the apparatus shall be
such as not to hinder
the use of in particular the following apparatus:
(a) domestic radio and television receivers
(b) industrial manufacturing equipment
(c) mobile radio equipment
(d) mobile radio and commercial radiotelephone
equipment
(e) medical and scientific apparatus
(f) information technology equipment
(g) domestic appliances and household electronic
equipment
(h) aeronautical and marine radio apparatus
(i) educational electronic equipment
(j) telecommunications networks and apparatus
(k) radio and television broadcast transmitters
(l) lights and fluorescent lamps.
--- End Quote
Item (i) clearly states that educational electronics are within the scope
of the EMC Directive. Unless, is there some other directive that
supercedes or augments 89/336 that reverses this requirement? What is your
definition for an experimental device? I am curious because we have an
educational product (made up strictly by electronics) that we redesigned
and EMC tested for CE Mark compliance.

Subject: RE: CE question
Hello Lisa and group,
If the equipment can be classified as experimental , which for education
purposes is likely, then EMC requirements can be excluded. This is not true
for Electrical Safety however, so if the equipment is mains supplied, at
least (may be more parts ) the power supply should me ce-marked for
electrical safety.
I got in mind here a set up like an electronic kit in which a lot of
separate units can be connected in a lot of ways to perform demonstrations.
If i misunderstood, my apologies !

Ing. Gert Gremmen

Onderwerp: CE question
I have a question regarding a unique piece of equipment to be shipped
to the EC. It is is a training system used specifically at schools
for vacuum training courses. Several components which make up this
system are CE marked while a few are not. My question is "Is there an
exception to the the EMC/LV directives which allows such training
products to be shipped without compling?" If so, what and where? and
also, what paperwork would be required to accompany the equipment?
Any help is appreciated.
Regards,
