I wanted to pose the group a question in regards to spacing requirements for
the U.S. Many UL standards allow for the exception of components (such as
semi conductors, switches, etc) to not meet spacing requirements (as they
usually have different standards they meet anyways) The question is

I, too, had nothing better to do.
Thank you.

Hi GroupNov 29.00
Can some one give the general description of what type of test that
EN60068-2-32 procedure 2 calls for. I have not yet received my copy of
EN600068 and would not like to get a jump-start.
Thank you in advance.
Sincerely

Here's Webster's Second Edition New World Dictionary definition:
ball bearing 1. a bearing in which the moving parts revolve or slide on
freely rolling metal balls so that friction is reduced 2. any of such metal
balls
I think, however, that it would be more appropriate and descriptive to
I'll note this and attempt to be more accurate in the future. Hopefully, it
will reduce your hatred to a mere peeve.

Actually, I had quite a collection of old electronic and telegraph
instruments, gotten from a local junkyard of which our landlord was the
owner. Alas, my small collection was junked while I was in the Army. My

Dear All,
I have heard rumors that the Japanese homologation requires test reports
(such as IEC 950 CB Test Report) be translated into Japanese.
Has anyone passed Japanese homologations without test reports translated
into Japanese?

My comments re Woodgate was confsuing. What I meant to say was the
transformerless SMPS s appear to generate considerable nosie as opposed to
the passive transformer. Is anyone concerned about this noise?

I'm sure we have been through this all before, but here goes :
For equipment certified by UL and CSA (and I assume by other
agencies, but I have no personal experience), the End of Line
Tests will be specified as part of your certification.
For Europe, there is EN 50116, which defines the
All,
What are the exact requirements for End of Line testing and do they
differ from country to country. We currently subject products to the
following tests:
1. Earth Bonding at 25A (resistance to be less than 0.1 Ohms)
2. Dielectric strength
Just a litle pet hate of mine, but ball BEARINGS consist of both the
races AND the STEEL BALL (or plastic sometimes) but that little round
bit we all like to use as missiles or for the game of marbles is a BALL
not a ball BEARING.

J.M.Woodgate's comments are very appropriate to identify where all the
conducted noise is coming from in consumer residences but does nothing to
mitigate the problem. The unfiltered SMPS used for replacement of the old
reliable non noise generating physical transformer contributes little or no
