RE: RTTE - antennas
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.

RE: CE directive (Warranty Defective Products)
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).

RE: Automotive Directive
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
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.
