Field trial requirements
Group, Are there any EU legal requirements regarding the supply of products for field trials that have not yet completed the CE process. Is it legal to do so provided the products are labelled accordingly, (Evaluation sample etc), installed in restricted locations and are still the property of the manufacturer (thus in effect not being made available as defined in the new / global approach) many thanks.

Correct submissions
Group, If a piece of telecoms equipment has the facility to use for example a headset that is not supplied with the product, for emc purposes it is necessary to perform conducted and radiated Immunity with a head set, however I have sampled 5 different headsets on the market (there are many more out there) with dramatic differences to the 1Khz demodulated tone on the line and acoustic (some have a comfortable pass, some fail). With this in mind how would an EMC submission be handled.

EU manufacturers
I hope someone can set me straight on the following matter regarding Technical Construction Documentation (LVD) in the following scenario: Manufacturer A produces and sells a product to the market and also sells it to Manufacturer B, Manufacturer B just re-names the product and also sells the same product under the new name as their own, I know that Manufacturer B produces a D of C but in this case has Manufacturer B got to produce a Technical construction file or just make a reference to Manufacturer A. Also just to confuse things both manufacturers are in the EU. Jon Jones - --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

RE: Immunity testing of Headset
Geoff, I have had further thoughts on the headset immunity testing: The requirements of an artificial hand on a telephone handset is to simulate a human hand on the handset, normally within a handset there are 2 wires being fed through the handset to the earpiece which would be enveloped in this copper hand. So as far as I can see and as the headset is hands free there would be no requirement for a copper hand. If the artificial hand were to be used as due diligence to the standard the question would arise as to where it would be placed, as normally there is no wires in the head band of the headset. Either between the Mic and earpiece (along the plastic arm) or around the connecting wire of the headset? Ideally both would be tested but due to time restraints etc not preferred. Regards, Jon Jones Senior Approvals Engineer Ascom Telecommunications Ltd. Jon, EN55024 uses the IEC 61000-4-x series to define the test set-up. I had a quick look at 61000-4-6 and could only find a reference to a handset. This, in turn refers to IEC CISPR 16-1 for the details of the artificial hand. The telephony sections of EN55024 are based on a standard POTS or ISDN audio telephone with a handset. In the real world, the effects of a human holding a handset and wearing a headset would be similar. Most handsets have a similar shape, and are catered for by CISPR 16. The answer to your question may be buried deep in one of the normative references. For EN55024 Annex A, you will need to measure the sound pressure level at the earphone, as you would with a normal handset. If you placed part of the headset in the artificial hand, you would be showing due diligence in meeting the spirit, if not the letter, of the test set-up. My opinion, not necessarily that of my employer.

RS232 un-earthed!
Group, Does anyone have any experience in the safety testing RS232 ports that is part of an un-earthed SELV circuit? In normal practice I understand that pin 1 is earthed for screening purposes etc, but are there any special circumstances where an earthed connection on the RS232 would be unfavourable.
