It isn't Amund's fault; the old Generic standards are defective in this
respect. The bit about the mains power is in clause 1, whereas the other
items are in clause 5, including ISM but not including any reference to
clause 1. The British Standard version of EN50082 actually draws
attention to this in the National Foreword. 

In EN61000-6-2, which is not identical to IEC61000-6-2, the four items
are all in clause 1, including ISM, with a footnote that ISM Class A is
meant.

SV: Industrial Locations

2002-02-20 Thread amund 

Jim,
You are correct, CISPR 11 refer to class A/B and the mains power
distribution system.
When I quoted the locations from EN50081-2 (emission), I forgot a footnote
so let me correct it:

- industrial, scientific and medical apparatus (ISM) (footnote 1) are
present
(footnote 1): As defined in EN55011, ISM class A.

The same footnote is present in EN50082-2.
Amund

Re: ITE for industrial locations

2001-12-05 Thread eric . lifsey 
Kim makes a good point about the mains isolation determining the standard 
to apply.

I might mention that EN 61326-1 makes no distinction regarding the mains 
network; it is only concerned with the application, or how severe the 
operating conditions might be WRT EMC.  There are surprisingly few 
definitions provided or needed in this EMC standard, and no conditions 
placed on "industrial" other than it is a harsh environment (per Annex A 
as provided in the 1998 amendment: "in close proximity to high-level 
sources of disturbances").

Hi Jeff and all

There are another issue here. When you say industrial could it also be 
light industrial ?

Remember that Industrial in EU is sites with it's own transformer at the 
mains.

If you are sure that your product is only Industrial just put a statement 
in the manual that the CE marking is for
Industrial locations only. Put the same statement with some more details 
in your Technical file and I  you can sleep
well in the future.

The only problem is if it is obvious that the product will be used in 
light industrial locations, then you should make
the statement very large and also put it into the marketing brochures.

Re: ITE for industrial locations

2001-12-05 Thread eric . lifsey 
Jeff et al,

Yes - it can be confusing, but IMO it's EN 61326-1:1997 A1:1998 for EMC of 
measurement, control, and laboratory equipment that applies.  Use the 
minimum requirements of Table 1, and possibly Annex A (industrial) if the 
equipment is advertised as enduring severe EMC locations.

IMO the ITE definition addresses function (insofar as Information 
Technology goes), but not application/location of the equipment, which is 
more important to EMC than a definition based on function.

If an ITE device is advertised and priced primarily for industrial 
locations, then it should not see use in the office/residential 
environment.  I suspect your pricing will naturally prevent most people 
from purchasing it.  For example, we make a pentium based computer in a 
couple different formats.  You can play games, browse the internet, or do 
word processing.  Priced at USD$4,000.00 with no keyboard, no chassis, no 
power supply, no mouse, no monitor.  So it isn't very appealing to the 
public where a higher speed office/home system can be purchased for 25% of 
that price and works out of the box.  It would be crazy to attempt to 
advertise our computers to the public, it would be wasted money.  So why 
test to ITE requirements, clearly a different location/application?

If on the other hand your device is priced and advertised for either 
market, then you could go either ITE or MCL.  (What is your empasis for 
sales?)  You could also consider in what way the safety requirements were 
met, as ITE (60950) or MCL (61010), and select the matching EMC standard 
or apply the correct safety standard.

Perhaps I should mention the fact that many industrial customers are 
buying inexpensive computers for their applications.  The cost is very 
appealing, and they can satisfy EMC thanks to high speed fiber optic bus 
extenders, Ethernet, or isolated serial busses that allow placement of the 
more fragile low cost computer in a "safe/safer" location (a benign 
control room) several meters away from the EMC, temperature, or other such 
hazards near factory machinery.  This approach is becoming very popular 
since it allows the industrial customer to keep pace with technology 
advancements at low cost.

Subject:ITE for industrial locations



Hello group,

I am in the process of defining a test plan for a product that fits nicely
into the definition of ITE as stated in
3.1 of EN55022:1998 and therefore into EN55024:1998 as well.  My issue is
that although it is obviously ITE
(Industrial network communication hardware) it is also designed for use in
industrial environments not
residential.  As hard as I try to justify designing the test plan around
EN61000-6-2 or even EN61326 I still
keep getting pulled back to the definition of ITE and therefore feel that
legally I must test to EN55022 and
EN55024.

I am seeing this as somewhat of a flaw in the system as I feel my product
should be evaluated to an
"Industrial" set of immunity tests.  Does anyone have any pointers on how 
I
can test the product within the
word of the law while still being able to sleep at night?  Must I try to
squeeze more out of the budget in
order to test to the legally required standards and then test again to the
ones that make sense?

I seem to remember a recent thread on this but of course I did not archive
it...

You do not 'legally' have to test to anything. Don't worry about the
CISPR-derived standards, which have not been written with different
environments fully in mind. If you are sure that the product is for the
industrial environment, then your professional duty is to apply the
'industrial' immunity standard.

No, it's a misunderstanding of the relationship between the Directive
and standards.

All you need to do is to *document* the reason for your decision to
apply the standards that you consider appropriate.

Absolutely NOT! There ARE no 'legally-required standards'. It is your
responsibility, as the manufacturer, to choose the appropriate
standards, using your technical and professional judgement. You cannot
even delegate this responsibility to a test-house.

RE: ITE for industrial locations

2001-12-04 Thread Gary McInturff 

Jeff,
I'm out of the office at the moment so winging it from memory, but I
believe the industrial scope addresses locations like power plants and
places with their own transformers etc - so its not commercial its really
industrial. Check the scope of the standard and make a choose from there. If
you are hanging these from power lines etc, you might also want to consider
heavy industrial.

Hello group,

I am in the process of defining a test plan for a product that fits nicely
into the definition of ITE as stated in
3.1 of EN55022:1998 and therefore into EN55024:1998 as well.  My issue is
that although it is obviously ITE
(Industrial network communication hardware) it is also designed for use in
industrial environments not 
residential.  As hard as I try to justify designing the test plan around
EN61000-6-2 or even EN61326 I still 
keep getting pulled back to the definition of ITE and therefore feel that
legally I must test to EN55022 and 
EN55024.  

I am seeing this as somewhat of a flaw in the system as I feel my product
should be evaluated to an 
"Industrial" set of immunity tests.  Does anyone have any pointers on how I
can test the product within the
word of the law while still being able to sleep at night?  Must I try to
squeeze more out of the budget in
order to test to the legally required standards and then test again to the
ones that make sense?

I seem to remember a recent thread on this but of course I did not archive
it...

Seeking words of enlightenment and thanking in advance.

Re: ITE for industrial locations

2001-12-04 Thread Kim Boll Jensen 
Hi Jeff and all

There are another issue here. When you say industrial could it also be light 
industrial ?

Remember that Industrial in EU is sites with it's own transformer at the mains.

If you are sure that your product is only Industrial just put a statement in 
the manual that the CE marking is for
Industrial locations only. Put the same statement with some more details in 
your Technical file and I  you can sleep
well in the future.

The only problem is if it is obvious that the product will be used in light 
industrial locations, then you should make
the statement very large and also put it into the marketing brochures.

Best regards,

Kim Boll Jensen

RE: ITE for industrial locations

2001-12-04 Thread CE-test - Ing. Gert Gremmen - ce-marking and more... 
Hello Jeff,

I suggest that you take the limit /test values from
EN 50082-2 for Industrial equipment, and take the test method
from EN 55024. You will see that the differences are
not that large, and you will feel comfortable having tested to
a more severe level of EN 55024 compatible with the limits
(even standard) as appropriate before EN 55024 was published
I suggest that you also test according to the published levels
of EN 55024 to ensure compliance to the letter of the standard.
Also (esp. ESD)may create problems at lower test values that do
not exist at higher values.
Normally extra costs will be very small using this approach.

If you still are not sure about your compliance to the requirements of
the EMC directive, ask a local Notified Body for a Statement of Opinion
about your files. You will find out that a good NB does not require you
to re-issue any tests, but just gives an onion about your approach
in view of the directives goals. That's why they are for.
Prices are much less then most think.

After all,

Regards,

Gert Gremmen, (Ing)

Test Levels for Surge in Industrial Locations

2001-05-11 Thread Bouse, John 


> Hello group,  
> 
Has anyone dealt with the "industrial" EMC test requirements for the
European Union?

In particular,  EN 61326  (EMC requirements for Electrical Equipment for
Measurement, 
Control and Laboratory Use)  specifies surge test levels of  1 kV
line-to-line and  2 kV 
> line-to-ground.
> 
> For apparently the same "industrial environment" (defined as Type 2),  EN
> 50270  
(Electrical Apparatus for the Detection and Measurement of Combustible
Gases, Toxic 
Gases or Oxygen)  specifies test levels of  2 kV line-to-line (differential
mode)  and  
> 4 kV line-to-ground (common mode).
> 
> I'd like to determine the following:
> 
a.   why would there be a difference in the surge levels for what appears to
be the same 
  industrial environment?  (perhaps because EN 50270 also applies to
apparatus for 
  use in hazardous areas?)

b.   is there is a commercially available AC-to-DC power supply  [an AC
adapter style, 
  230 VAC to 12 VDC at 2 Amps]  that can handle the higher level surge
defined in EN 50270?

All responses are greatly appreciated.
