RE: RTTE - antennas

2003-05-16 Thread Gert Gremmen

Within the RTTE harmonized standards
fa. for SRD's a distinction is made between
equipment having

1/ internal and
2/ external or
3/ dedicated
 antenna's.

If your product is tested as an equipment having an external
antenna, the test program will be such that the type of
antenna should not have impact on the RTTE properties.
Of course, otherwise a HAM product (transceiver) would not
be able to be sold in Europe, as the antenna is unspecified.

As an antenna is basically a passive element (at least it should),
no detoriation of the transmitter properties is to be expected,
but for directional properties.
Some products won't be allowed with external antenna's,
if the requirement is to limit it's geographical
range (due to f.a. frequency sharing).


Then a dedicated antenna is part of the approval procedure.
Of course this IS the always case with internal antenna's.

Many SRD devices use dedicated or internal antenna's only.

I have to add that the requirement for external/dedicated
antenna is most often implemented on regulatory level,
and not specifically within the RTTE.
Any permission to use the equipment will be with a prescribed
antenna type, and often heigth. Of course,
this is country and product type dependent, and subject to
frequent changes and (hopefully) harmonization within  the EC.

It depends on which ETS/EN standard is applicable for the Radio some of them
have the antenna parameters specified as part of the spectrum parameters.

Assume a CE / RTTE approved radio transmitter system, which consists of an
indoor unit (modulator), an outdoor unit (HPA/LNB/OMT) and an antenna.

If you change to another type of antenna (passive), will the system still be
compliant to the RTTE directive ? Is antenna testing a part of the RTTE
testing ?

RE: CE directive (Warranty Defective Products)

2003-05-16 Thread Chuck Seyboldt


See 1999/44/EC for warranty for consumer products.

85/374/EEC relates to defective products.  Defective
products does not mean not conforming to specifications, but
means a product that causes at least 500 Euros worth of property
damage (other than the loss of the product itself) or personal
injury.  Some products that conform exactly to specifications
indeed do cause damage (and can be found defective); and some
products have gross deviation from their specifications yet never
cause property damage or personal injury.

85/374/EEC has been amended by 1999/34/EEC, requiring
member states to include primary agricultural products to the
list of products that can be defective.

While on the subject of general directives (not CE
marking), 92/59/EEC is a General Product Safety Directive for
products not specifically covered by any other Directive (e.g.
wind chimes, bird baths).

 All,

 As I read this document, I don't come up with the concept of a
 3 year warrantee on the product.  What I see is that the
 plaintiff (the person injured by the product) has 3 years from
 the time they figure out whose product it was that injured them
 to make their claim for damages.  This isn't a 3 year warrantee
 that the product works, or you will fix it.  This is a 3 year
 statute of limitations (as we would say in the US) during which
 time the person injured by the product must make a claim for
 compensation.

 A slightly different situation than - I bought my stereo 2
 years ago and it's broken.  Please fix it.

 Or am I missing something here?

RE: Automotive Directive

2003-05-16 Thread Chris Chileshe

Hi Bob,

You wrote ..

 I have a copy of the Directive 95/54/EEC on order.

Unless things have changed from when I last looked,
one should be able to download the directive from sources 
such as http://www.europa.eu.int

On naming, unlike the other directives, it ends in EC rather 
than EEC i.e. 95/54/EC

 The Directive only contains tests for broadband emissions, 
 narrowband emissions, and radiated immunity.

True. 

It sets limits for emissions based on ... CISPR 12 I think ..
and sets the radiated immunity level at 24V/m, so a general
test level of 30V/m is the norm. 

  No tests exist for conducted emissions, immunity to transients,
  or ESD.

True.

 Do (or can) auto manufacturers require tests outside of 
 the Automotive Directive?

Yes. And they do. Almost invariably, depending on the product. 
This is because the directive covers all equipment used in vehicles 
but makes no distinction between safety critical control-related 
equipment such as ABS, Steering, Engine management and less 
critical equipment like car stereos.

That it doesn't address the power supply transients has been 
deemed a shortcoming by some but has been defended by others 
in some circles where arguments such as the equipment could 
be self powered have been presented.

The Agricultural and Forestry vehicle manufacturers will often insist
you apply EN ISO 14982, which covers the requirements of the 
directive but includes the 'missing' tests. Individual manufacturers
then begin placing restrictions on how much quiescent current draw
your equipment is allowed to draw in 'stand-by'.

Often, it is best to think through how, when, where and by whom 
the equipment will be connected, and then devise a complete 
approvals strategy based on this info but I am sure you know all
this. 

In addition to including the additional tests, vehicle manufacturers
may also require higher stress levels for radiated immunity. 50V/m 
and 100V/m are common examples, and the conducted immunity 
spectrum often extends down from 30Mhz to audio frequencies.

RE: Automotive Directive

2003-05-16 Thread Barker, Neil

Bob,

The statements that you make are true.
The Directive only sets out minimum requirements. Any specific manufacturer
may require suppliers of sub-assemblies to meet some limit that exceeds
these minimum requirements. He is not obliged to accept any and all
sub-assemblies that meet the minimum requirements. Typically, the radiated
immunity requirements are quite low by automotive testing standards. Whereas
the Directive requires immunity to 24V/m, I have heard of manufacturers
testing to 200V/m.
As for immunity to transients, etc, ISO 7637 is very likely to be cited.
Hope this helps.
