Hi
When applying for Taiwan BSMI accreditation it is necessary to have a Taiwan
contact point. We are considering applying for accreditation. Can anyone
recommend a contact person?

Rich suggested testing the standoff for flammability, then showing the
inspector that you are indeed using the same standoff as tested when a
factory inspection is performed. This route would make me uncomfortable for
a few reasons: 1. It may not pass, 2. Standoffs are a very cheap commodity,

Gentleman,
After reading the discussion, I was curious as to if anyone has been able to
find a Nylon or other 94V-0, 1, 2 rated standoff that is recognized? Just
curious if one exists, since I have yet to be able to find one.
Thanks,

Hi Kaz:
Answering the question, what's the safety concern,
is a reverse-engineering process with respect to the
various requirements contained in the standard.
Applying the requirements of the standard to the

What about the last exemption in 4.4.3.3 which states that the requirements
of 4.4.3.2 don't apply to: integrated circuit packages, transistor
packages, optocoupler packages, capacitors and other small parts mounted on
material of flammability Class V-1 or better?
Since
Rich said The small-part exemption cited by Terry only applies to small
parts separated from electrical parts by at least 13 mm (1/2-inch) of air.
Actually, the 13 mm separation only applies for small parts near electrical
parts which under fault conditions are likely to produce a temperature
I certainly have a lot of small plastic parts in my products which I
consider to be exempt and are not described in any procedure - and they
may well be a lot bigger than your standoff !!
I certainly think your agency is not-picking !!
One point to consider is that I write the procedure for UL
Rich,
As always, you've succinctly provided the full story on an approach that in
this case, will work to get Terry's product approved. I think your
interpretation of my suggestion of asking what's the safety concern is a
bit off however.
Personally, I'd rather have a 5 minute conversation
Hi Kazimier and Terry:
Kazimier suggests asking the question:
what's the safety concern
Unfortunately, safety certification houses
do not have the option of accepting products
based on the answer to this question.
A safety certification house certifies a
product to a standard.
Peter,
I looked through some of my books last night and this morning, and found
suggested spacings of:
* Greater than 20mm, 8.4mm, 5mm, or 10mm between circuits and:
- Points that a person could touch.
- Ungrounded metal parts that a person could touch.
* Greater than 2.2mm, 0.5mm,
Hi Terry,
Sounds like a discussion with your agency safety engineer might be in order.
It's certain there's a line of reasoning behind the new approach taken by
the agency, that you've described below. Question is, since the standard
clauses you've called out make certain allowances, the real
Hi group!
I need a sanity check on a `new approach' our safety agency has recently taken.
We have an open frame power supply ( has all the certs through the CB report
etc. for EN 60950 UL 1950 )
On of the conditions of acceptability is one mounting standoff shall be
insulated. We have this
Don't forget that 61000-3-2 has been amended with A14, which gives you the
option of avoiding the special wave shape criteria and classifying most
items (excepting PCs and televisions) as Class A.

Steve,
Your comments regarding power factor correction are on target. You are
correct about the standard becoming effective the beginning of this year.
Don't miss the advantage of A14 which is also now in effect. It is my
understanding that Class D applies to computers, TVs, and monitors;
Bob,
If you use ISDN, and 3.1 kHz telephony
and have a handset, then it's worth
looking at TBR8 as well as those mentioned
by Praveen.
The TBRs and associated specs can be downloaded
for free from the ETSI web-site

Jon,
There is no specific requirement for power factor correction as far as I
know.
The Harmonics Emissions Standard BS EN 61000-3-2 1995 became mandatory
01/01/2001, this sets limits for the harmonic disturbance permitted on the
mains - so it adds up to the same thing. .
It applies to all
Hi Bob,
Yes, RTTE directive is the one.
Assuming no radio devices, the following requirements apply.
EMC directive : EN 55022 emissions and EN 55024 Immunity

The following telecom standards also apply on a voluntary basis.
PSTN : TBR/CTR 21 and TBR 38/CTR 38 and ITAAB Notes
