Hello All,
I'm in the process of specifying an external Ac to Dc power Adaptor which
will be
used for one of our products. The transformer is to be mounted inside an abs
plastic housing with an Ac supply cord and a Dc output cord. Both cords are

Dear Tony,
All Devices connecting to the Public Switch Telephone Network (PSTN) needs
to be tested to FCC Part 68 before it can be sold in the US. This would be
similar to the testing that I expect you would have tested to, for the
crossed hockey stick mark for Europe.

Greetings,
What CE directives and hence what test standards apply to a small
ultrasonic cleaner (sometimes referred to as a jewelry cleaner) when it is
included as an accessory to an ITE product? The ultrasonic cleaner is an
off the shelf product from another
In my opinion, the cleaner is not an accessory to the ITE since it has no

perform its intended function (clean jewelry) and so EN 55011 would
apply. Choice of Class A or B, as appropriate. Class A if not used in a
Dear Rebeca Chan,
Based on the information that you provided, a device such as your electrode
device could be classified as a Class I device. A submittal to FDA under a 510k
plan may or may not be necessary. It is hard to say with the limited
information provided. The key question here is how
Here is a little more information that I have on this subject. I am not
aware of any other national deviations specifically covering Cadmium
batteries:

I am trying to sort out an an apparent contradiction between the main body of
the harmonized EN 60950 and the national deviations that appear in Annex ZB.
I would appreciate some assistance from the safety professionals and

Hi Joe:
An excellent question !
Let me ask one or two of my own here.
1. Are we sure that both Sweden and Norway are currently EU members ? Not

items in annex ZB
