Dan,

the Japanese Jate Mark, from the Japan Approvals Institute for
Telecommunications Equipment. It is a Telecommunications Terminal
Equipment Conformity mark-- see
Dan,
If you go tohttp://www.cellotape.com/contents.pdfpage 9, is
symbol 139 the one that is on your wireless unit?
They don't tell what the symbols mean in this design guide, but maybe
someone can recognize it now...

Hi Gary:
As a result of searching for my copy of the
indoor use only symbol, I discovered that
I have a reference to the standard where the
symbol is published:
DIN 30 600 Reg. No. 02808-3
If one of our subscribers has a copy of this
standard, perhaps he could verify the
reference.
Thanks for the input from everyone. Based on the input, I have come to the
opinion that pre-scans on all CPU configurations according to ANSI C63.4
should be carried out and a final scan performed on the worst case
configuration of those, assuming nothing too drastically different rears its

Neither one of them looks like a C with a lightning bolt to me,

Thanks to all that have identified the first symbol as in-door use
(what I
thought). So far no information on the other symbol, but I should have noted
that it wasn't on the power supply but another little wireless device. I tried
looking in the Wifi websites to see if they mentioned it
Hi John:
It is not an ISO or IEC symbol.
It is either in IEC60417 already or will be in the future.
It is not currently in IEC 60417.

adoption of this symbol into IEC
60417.)
Since one of our members could not

Sir
What is the rationale given for some people not accepting an EN standard
issued by BSI?
My employer typically buys EN stds from BSI. Is there something different
about BSI-printed standards?
thanks for info.

For testing purposes, we use EN 55103:1996 Parts 1 2 but our EU
Declaration of conformity states compliance with BS EN 55103:1997 Parts 1
2. As the majority of our products are exported to mainland Europe should
we specify compliance with the EN or BS EN version of the standards?

All,
My apologies if this is message is a duplicate--
I think I replied only to Gary the first time...
I believe the second mark that Gary describes is the

mark for the DoC and Type Approval processes.
I believe this is also known as the CNS

Good morning:
We are a US company manufacturer of TVSS:Transient Voltage Surge
Suppressors (SPDs: Surge Protection Devices).
We are selling these products in China, and if I am not wrong the

Dear all,
This brings to mind about the rational behind the existence of product
standards.
Given the typical product, I am convince that it is 'theoretically'
impossible to predict which 'typical' configuration can give you the worst

Gary,
The symbol you described is to indicate Indoor or Outdoor use. If the
arrow points outside, it means For outdoor use. If it points inside, it
means For indoor use only.
This house symbol is not an IEC recognized one but it IS required by some
countries for certain types of products,
This is a multi-part message in MIME format.
The nearly closed C with a horizontal lightning bolt separating top and
bottom appears to be a description of the Australian C-Tick mark. I believe
it means the device complies with the Australian EMC requirements.
