Well, playing the devils advocate here. If RAM is an apparatus if you can
install it on into a socket, but not an apparatus if I buy the RAM as a

Hi John:
Some have questioned whether 61000-3-2 is even an EMC standard!
If not, what do you think it is?
I fall into the group that question whether 61000-3-2

I understand the point you are trying to make, but I see the memory more
analgous to a resistor array than a disk drive. Certainly there is much less

I took a second look at the EMCD guidelines, chapter 6 and have changed my
opinion.
In the EMCD guidelines, if the DRAMS are sold to the end user, applicability
of the EMCD comes down to whether the DRAM modules perform a direct function
to the end user. The examples given in chapter 6 of the

Most certainly, it is exempt from the LVD.
As to EMC, this device has no clock to radiate by itself. It is subject
to the EMCD when and only when incorporated into an

Amund,
The directive contains all of the testing methods required and does not refer
to other standards.
There is a new draft automotive EMC directive that contains requirements for
ISO 7637 Transients as well as radiated emission and radiated immunity that
are in the current directive.

Amund,
If your TV is intended for use whilst the vehicle is running then it should be
e marked to 95/54/EC.
This directive is product specific and includes the tests for radiated
emissions and susceptibility. However note that it does not deal with
conducted phenomena! so you may want to CE as
