Hi John,
I beg to differ on this one. Intended application or use environment always
plays a big role in determining standards and limits that apply. A modem can
be classified as Class A, as can a computer destined and marketed strictly
for industrial environments.
In the overall scheme of
If it attached to a PC, it is a PC Peripheral and will need to meet the
requirements of a PC. It will need to be tested as part of a system
which includes the Host. a PC, by definition, is a Class B device and
can be either Certified, or preferrably, use a DoC.

Pierre,
Another way to analyze the problem is the intended use, cost, and how
you advertise the product. Below is a small excerpt from the FCC part 15 rules
defining a computer.

which use a standard TV
That's the justification that I was looking for.
Thanks.

Hello all,
I have to clarify a point to classify a product regarding FCC part 15 rules.
The product is a scanner used in the photographic world. It scans negatives
films and converts it to digital files.
This scanner can be used as a stand alone one, or included in a bigger
machine which makes

Hey Doug,
I guess it seems to me that if the device is non-functional, then none of
the regulatory information applies.
I see your point, but that's not how the lawyers think!
I was thinking about manufacturer ID's, certification file numbers or other
traceability-type markings such
Hello all,
Didn't get many responses to this but I want to pass some information on
regarding why 25 Amps was selected as the default test current. Apparently this
is a legacy value from the UK when 12 amp circuit breakers were being used as

regulators to convince as you have labels.
As a former certifier, I have a few questions that I think would need to
be resolved. For example, if there were some question about the device that
