Can anyone state any detailed examples where a proper product test suite
under the RTTE directive could not be found in the harmonized standards
(TCF route for conformity)? Other than the OJ, where can previous decisions
from notified bodies be found for reference?
Sincerely,
Stuart Lopata
For a listed product, is a multiple listing not required? It certainly is
here in Canada. Remember, the trend at the FCC is to ensure that the FCC
ID matches or is linked to the company placing the product on the market.
The other question to be asked is, is the product truly identical, or
Has EN 50140:94 (EMC/basic; radiated RF EM field immunity) been replaced by
EN61000-4-3('99)? Are they identical? At USD120, I want to confirm there's some
difference 'tween the two. Under the auspices of EN61326:97 (...measurement,
control and laboratory equipment EMC), the former doesn't
Hi David,
It's good to hear from someone who has spent a couple of second shifts
out in the cold 10m test site with me. Hope all is going well.
Your answer would be a possibility for self-certification cases.
However, if we want to use an NRTL mark such as UL, TUV, CSA ...; then

Hi, Folks -
I have been asked about the whereabouts/contact info for an ESD test
equipment vendor in Canada (last know address Etobicoke, ON) who go by/went
by the name of PICO Q.
Does anyone have any information that they can pass on so that I can forward
it?
Kindest regards and thanks in
Chris,
Greetings! You may not even need to perform production line hipot if
the unit is a fiber only product. Since the mains are SELV (unless you
are shipping to certain Euro Telco's) the only time you should need
production line hipot is if you have wired (TNV-2 or TNV-3) interfaces,
Chris,
The reason that I agree with John that you should be testing both is that the
custom DC cable that you are assembling and shipping with your product can have
marginal or failed insulation that the hi-pot test would catch. Such
potential failures can have spectacular results at your
It private branding of equipment A to become B is the issue, then there is
no issue. The FCC ID belongs to the manufacturer of A and no change of the
Grant is required. A new Grant would be required if the equipment were
manufacturered by someone else.

I think what the question is here is not so much as
'Class' of emission levels I think he
is refering to an OEM product.
He is buying completed/fully-functional product A and
will market it as product B. They are one in the same.
His question is whether he can use (transfer) the FCC
ID issued
If you conduct the functional tests of the chassis
with the DC cable that ships with it, then it's
not much of a hassle and you know that the whole
package is fine.
If you merely insert the cable during packing for
shipment, consider doing a hi-pot on the cable itself
on it's production line.
Tommy,
I'm not exactly sure what you're asking. If you're asking if a Product
which is labeled as Class A can be relabeled as a Class B product because
they look the same, the answer is no. The product must be properly retested
to assure its compliance with the Class B limits and then you must
An industry specific guideline (SEMI S2, developed for the semiconductor
manufacturing industry) that I spend a lot of time with has cautions against
hazardous power, defined as 240VA or greater regardless of the potential.
In the same industry, fire risk is a very muddy topic to sort out. In a
Hi all,
I have a question.
I have a 48VDC powered product which will be hipot and ground continuity
tested off of the production line in order to maintain agency
certification.
The product uses D-shaped three pin power connector. (Same size as a
DB15, but has three large power pins instead
I am looking for a lab that help with this testing. Please reply offline.

Not to mention Lithium Batteries.
An A sized LiSo2 cell can still deliver more than 90 (NINETY) Amps After
being short circuited for 15 minutes.
Lithiums can also explode - which is why it take many hours to verity and
test the charging and ANTI-charging circuits in some products.

Hi
I think this gets back to what John W originally stated. A safety critical
component is any component whose failure,
modification or absence, will affect the safety of the product. Front of 950,
defines also defines Safe as not causing
a fire hazard.
There is no clear cut list of what is

We all know hazards come in all colours of the rainbow
especially fire hazards :)
My mail however, is no just targeted

just safety related components,
Hi Folks
I agree with John W - and a single fire can (and does!) kill and injure FAR
more people than a single electric shock.
Additionally, a large number of products are SELV and/or battery operated
where there is no shock hazard but is often a fire hazard - think of the
power available from

A model has Fcc ID.It is Printer.
Our buyer sale A model product to maket as B .
There are not differnt between A and B.

Is it possible?
If not,How can I do for get Fcc ID ?
Best regards.
