Re: EN equivalent to UL1951

Fowell,
I will let you determine the cross reference - but the site that lists
standards harmonized to the LVD (and the other new approach directives
such as EMC and Machinery safety) is :

"http://europa.eu.int/comm/dg03/directs/dg3b/newapproa/eurstd/harmstds/reflist.html";

It is maintained by DG III

Gary, Kevin, Barry,

A list of the current 'harmonized' declared articles with the applicable
standards for Australia can be found in AS/NZS4417 part 2. The separate New
Zealand list is also in this document. An electronic copy can be obtained from
the Standards Australia www.standards.org.au. for a fee.

I don't have one to hand at the moment, but from memory it includes all mains
plugs. i.e. the list includes plug packs (plug mounted transformers), as well as
any power plug or appliance coupler.

Barry, does the  marking relate to just the flexible cable or the plug as
well?

Sorry I don't have a legal type answer for you, although I agree that it is
against the spirit of the directive. I just though I would expand the
controversy and ask if you know if they are also demanding that declarations
for other directives like the LVD are also included with the shipment?

Hi Leslie,

You may try a very convenient hand-held RF analyzer, Site Master 
(http://www.global.anritsu.com/products/test/rfmicrowireless/s100_s200a_s300

Master is much less than Time Domain Reflector.

French Customs demand EC Declaration!

1999-07-14 Thread roger . viles



Recently French customs have started to demand that shipments of CE marked
electronic products are accompanied by a copy of the EC Declaration of
Conformity to the EMC Directive. Companies are having product held up and are
being fined.
This seems contrary to the spirit of the single market and is NOT envisaged in
the  EMC Directive, which requires only that the Declaration be held in the EU.
It is required by French Law under "Bulletin Officiel du Douane"  no. 6267 of 26
June 1998. This includes a specific law: DA no 98-112 - E/S (P.6112) concerning
EMC of electrical and electronic equipment.
This includes a section (III - Role du Service) which reckons that any
importation is the first placing on the (EU) market of that item and demands
that the importer must produce, at the time of importation, the necessary
documents, including the EC Declaration of Conformity, in order to support the
customs declaration. Production of the document at a later date is not
authorised.

Because customs inspections are applied only to goods from outside the EU, the
problem occurs with products imported from US, etc.

Does anyone have experience of this or believe it contravenes any EU laws?

Thanks for any help,

R&TTE Directive - Transitional Period

1999-07-14 Thread WOODS, RICHARD

Every time I read this darn Directive, I find something new or I form a new
opinion. Now I have questions about the transitional period found in Article
18.2.

"Member States shall not impede the placing on the market and putting into
service of apparatus which is in accordance with the provisions in Directive
98/13/EC or rules in force in their territory and was placed on the market
for the first time before this Directive entered into force or at the latest
two years after this Directive entered into force."

Assume that the product is radio equipment not subject to 98/13/EC and is
currently being sold in the EU. This equipment is subject to the "rules in
force" in the member states - the transposition of the EMC Directive and
national radio regulations. Therefore, it would appear that this equipment
may continue to be sold for the next two years without the need of complying
with the R&TTE Directive. Also, new radio equipment not subject to 98/13/EC
but complying with the present national rules could be placed on the market
during the next two years without the need of complying with the R&TTE
Directive.

Am I correct?

Re: Just safety - nnot telecomunications

1999-07-14 Thread Barry Esmore

Hi Kevin,

Most of what you have said is correct except I believe the authorities here
consider all power cords (except for  marked) to be declared whether
they are detachable or not. This is how we viewed the situation when I was
involved in regulatory policing some years back, and I would be interested
in knowing if the regulators had changed this policy.

Also, other declared items that could be associated with Gary's equipment
are the Australian plug, appliance connectors (IEC320 type plugs), and the
majority of detachable power supplies.

Phantom Power for NT

1999-07-14 Thread Nezam Najafi

To All:

I have ISDN card that runs on +/- 2.5 Vdc. This is on my  U- interface
board. I need to connect it the Net work Terminal. I have a  36 Vdc to 90
Vdc from exchange. How would I modify the design so that I can superimpose
the phantom power and still be in compliance with CTR and FCC.  I appreciate
your advice and assistance in advance.

Gary,

The ACA (Australian Communications Authority) is only responsible
for EMC,
Radcoms and Telecommunications. It is not responsible for any other
type of
product.

The safety of any product placed on the Australian market is
controlled by
"trade practices" type legislation and essentially requires that any
product meets the appropriate and relevant standards for such
products.  In
the case of IT equipment the relevant standard is AS/NZS 3260
(Australia's
version of IEC 950).  NOTE:  AS/NZS 3260 is essentially the same as
IEC 950
however compliance with IEC 950 by itself is not considered
sufficient in
many cases.  

If you have your product tested for IEC 950 PLUS Australian
deviations in a
CB accredited lab you will have no problems.

In terms of electrical safety the Australian State regulatory
authorities
have listings of "Declared Articles" (used to be known as
"Prescribed
Articles") and if the device/item is included in the "Declared
Articles"
listing, formal approval is required with an electrical authority
(utility
provider) in one of the Australian States (approval in one State is
accepted in all other States).  In essence, the only thing at the
moment
impacting IT equipment on the Declared Articles listing is a
detachable
power cord.

There is not much available on the internet regarding these
requirements. 
You could check the following URL for a very basic few paragraphs on
what
the State of New South Wales (Sydney is in the State of New South
Wales)
has available on the internet.  there is no documentation however:

http://www.fairtrading.nsw.gov.au/Products.nsf/All+Products+Docs/37A6ECBE54
30E7384A25677C002C04B0?OpenDocument

Summary
For IT equipment, no approval is required, except for the
possibility of a
detachable power cord.  An electrical authority in any Australian
State has
the power however to request evidence of compliance with the
appropriate
electrical safety standard for any product offered for sale in that
State. 
Usually this only occurs when a complaint is made about some
equipment or
an incident occurs.  It is my recommendation any supplier ensure
they are
able to provide at short notice (10 days) a test report, by a
reputable
laboratory, demonstrating compliance with AS/NZS 3260 or IEC 950
plus
Australian deviations.

Hope this helps.  For more detailed information contact me directly
(see
bottom of email for contact info).

Kevin

FW: Computer Monitor Magnetic Immunity

1999-07-14 Thread Arun Kaore

General Immunity thresholds for computer monitors:

30-450Hz: Approx. 160-170 dBpT
450Hz-15kHz: 100 dBpT

I have generally seen good immunity at frequencies in excess of 15kHz. 

Tests performed with MIL-461C RS01 loop/audio oscillater+audio amplifier.

Monitor most sensitive when disturbance is applied 5 cm away from the outer
shell near the yoke coil.

Hi Listmembers!
Does anyone have an estimate of the magnetic field immunity levels of recent
production computer monitors? What levels, in Gauss or Tesla, do monitors
actually start to show disturbance? And at what levels could you expect a
typical monitor to be not just annoying, but virtually useless?
Thanks,

Re: 50 ohm & 75 ohm

1999-07-14 Thread Cortland Richmond



Leslie Bai wrote:

Anyone there can share the experience to measure
cables' impedance thus to identify whether a BNC
is a 50 ohm or 75 ohm cable.

The SECOND simplest way I've found (short of using an SWR meter and a 1:1.5
transformer)_ is as follows:

If you have an impedance bridge operating in the high MHz region, you need
only measure a quarter wave of coax -- as evidenced by inverting the open
circuit at its far end, at any convenient frequency, then measure the
capacitive reactance at half the first frequency. Alternatively measure a
shorted quarter wave stub -- as  evidenced by an infinite or very high
impedance reading -- and then look for the inductive  reactance at half the
frequency.

The reactance of a 45 degree line is equal to its characteristic impedance,
with  the sign depending on the termination.

This will not only tell you "higher or lower" but will identify odd ball
coax which might mess up a whole test. Don't ask how I learned THAT. (grin)

Good luck!

RE: 50 ohm & 75 ohm

1999-07-14 Thread Qu Pingyu

Bai:

If you have a Network Analyzer, just connect the cable to the two port of
the analyzer through a BNC-SMA adpator. Measure the reflection coefficient
(S11 or S22) and the 75 ohm cable should have a larger reflection. That's my
expensive way of doing it.:-)

Alternatively, if the two cables are made of the same material, maybe you
can check the ratio of outer conductor radius vs. that of inner conductor.
The one with larger ratio should have high impedance.

Just safety - nnot telecomunications

I'm pretty frustrated trying to officially determine the safety requirements
for Australia. I can't seem to get a handle on the ITE - but not
telecommunications - stuff. The EMC I have handled but want to confirm what
safety standards I need to meet. Again, I've tried the ACA URL

  without success. They
have not responded, but there site seems to address only the EMC and safety
requirements of telecommunications equipment. What is the status on just
good ol' safety for ITE. Anybody have a different URL than the above.
I apologize for asking this question when we just went through it not too
long ago, but I took the URL and thought I was home free but I'm unable to
get ACA to respond to the e-mail or find a link that doesn't tie into the
telecommunications.
