Hi,
Here in Europe, some EMC directives will come into effect shortly.
I'm not an expert here, but this is my understanding of the situation
from what a customer told me:
For the last few years, adherence to these directives has been
voluntary, but from January 1996, these directives come fully into
force.
Strangely enough, there appear to be no "standards" as such to back
these directives, although there are some voluntary (whatever that
means!) standards for emmisions (EN55024) and immunity (EN55022).
Apparently, these standards are similar to FCC standards in the US.
Adherence to these directives can be to 2 levels: Class A (commercial)
and Class B (domestic, more stringent than Class A).
Questions: Does Digital intend their hub products to be conformant to
these directives?
If so, to class A or class B?
If so, will this adherence depend on the media (UTP, Foil
STP or Braid Screened TP) or will it be for all media types?
What's our corporate line on this? My immediate question is about
hubs, but what about our other active and passive (eg. ODC) products?
FYI - some of our competitors are starting to claim comformance to
Class B, and could start to use this as a product differentiator
against us if we don't.

| 2500.1 | Hello...hello... | CMOTEC::CHOI | Shaking and Moving | Mon Jul 17 1995 06:24 | 16 |
Nearly a week later and there's still no answer. Does this mean that
1) Nobody read .0
2) .0 has been read and we're working on a response
3) .0 has been read but we have no response (and didn't know this
was an issue)?
If 3), can I suggest that we *will* need to have a party line on this as,
potentially, non-compliance to mandatory EMC regs will cause us great
difficulties in Europe next year.
Any status?
Clinton

| 2500.2 | Your question has been forwarded..... | NETCAD::BATTERSBY | Mon Jul 17 1995 10:25 | 9 | |
Clinton - You might try contacting some individuals such as
Bill Bogert (NETCAD::BOGERT) or Rick Busenbark (NETCAD::BUSENBARK)
directly, to see if they can help you with your area of concerns.
There are people who may be on vacation, and that may be why you
haven't received an answer in here. I will forward your note to
both Bill and Rick. I'm sure there is *someone* who is aware of this
issue.

The man to talk to is Boris Shusterman, FCCVDE::SHUSTERMAN. Boris is well aware of the changes coming in the European EMC regulations and has appropriate plans for compliance for our various networking products. I'll let Boris speak to them....when he returns from vacation. John | |||||
| 2500.4 | Yes, we do comply... | CMOTEC::CHOI | Shaking and Moving | Mon Jul 24 1995 06:40 | 33 |

Yes, we do comply to the European CE mark requirements. As a matter of
fact, these requirements are part of the DEC103 standard. This standard
is internal to Digital, of course, but it is based on the directives of
European markets were applicable.
The requirements are not law yet (they become a law on January 1,
1996), and most of it is related to the immunity testing (ESD, EFT, PLT
and Radiated Immunity). The emmisions part has been a law for a long
time, in Europe it is the CISPR 22 limits. There are also, just as in FCC
requirements, class A and class B.
The CE requirements are divided in class 1 and class 2, where class 2
is more stringent. Now, the HUB products - we aim at compliance with
class A limits (FCC and CISPR), with immunity testing limits set for
class 1.
For the reference - we, in Networking organization, were the first in
Digital to recognize the need for CE compliance, and all HUB products
went that way since the beginning. We also have a team to push all
products which were designed prior to that time and intended to stay on
the market to get the CE certification as well. This is an ongoing
process.
Note - the DEC103 Std is a document which coveres all aspects of
testing, etc. in details. The strategy is set by the Domain Office,
which is in Marlboro.
