Product Family Standard ApplicabilityHi John and All,
You should definitely use the Generics, unless the product is going to be
included
in the newer system as a system component, after which it is going to be
part
of a sold system in an other product family .
Take f.a. a micro controller in a separate enclosure, this is a typical
example of an ITE
product. Once incorporated as an add-on in a vacuum cleaner ( heck of a
model !) it
should comply (incorporated) to the house hold appliances standard EN
55014 - 1/2 and
to EN 61000-3-2/3 of course.
I'd go for commercial/residential emission testing (EN 50081-1 ) in
combination with Industrial
immunity testing levels, - best of two - , most difficult to meet but
definitely covers your ... when
someone wants to challenge your compliance.
As the product is essentially ITE, you might also opt for EN 55022 which is
basically the same,
but more specific.
Be careful however, that also the commercial (lower) levels of immunity are
tested. Sometimes lower
levels of immunity testing create different behavior as higher levels, not
in positive sense.
This has been reported frequently with ESD testing but might be applicable
to other transient
tests too.

Subject: Product Family Standard Applicability
Hello all,
I had an EMC standard applicability question posed to me, and I am not
quite sure how to answer.
What makes this difficult is that I have been asked not to reveal
specifics.
Here is the scenario:
A company is going to develop a product which can be used in a number of
markets - from commercial (in a clearly
non-residential environment) ITE market - industrial with other markets in
between.
There are no 'product family specific' EMC requirements in place at this
time for this type of product.
However, the 'product family' that the new product can be categorized is
listed under the
'ITE' heading in product safety standards UL1950 3rd Ed, EN 60950, and IEC
950.
One of the target markets (not ITE) of the product will generate at least
60-70% of the product sales. That particular market,
does haveit's own 'product family' EMC standard for the various
electronic devices that are 'essential' for operation of the systems
listed in that 'product family' standard.
While this new product is 'not essential' for the operation of the type of
systems that fall under the product family standard
(in fact, those systems have worked for years without this product), the
product can
be used to 'facilitate' extended operation of such systems.
(NOTE: The EXACT same product can be used in a variety of other markets
not even remotely affiliated with the
market).
Does the new product have to meet the 'product family' standards of the
market in which it will primarily be used?
(even if it is considered 'non-essential for proper operation')
Or can the generic (read as ITE) standards be used?
Your kind thoughts/opinions please . . . (I hope I have enough disk space
for this one . . . LOL!! )
