I fully agree with Richard Hughes – it is an interesting article but those of us who have conducted “Flight Safety” work will find it VERY weak is its content and treatment. Whilst EMC interferes (unless you are sitting in a microwave oven) - it is Product Safety (or the lack thereof) that kills! Furthermore I challenge anyone to demonstrate that the EMC related fatalities could not have been caused by a single components failure. Best regards Gregg

Note however that it states in regard to the LVD that: "The Low Voltage Directive (LVD) Although the LVD (73/23/EEC, modified by 93/68/EEC) is generally reckoned to cover functional safety, there are no words in its text that specifically mention it - never mind EMC-related functional safety" While this is accurate as far as it goes (and remembering that the Safety Objectives of the LVD were published in 1973), it could give people a false impression. The February 2001 version of the Commission publication "GUIDELINES ON THE APPLICATION OF COUNCIL DIRECTIVE 73/23/EEC" states: "The Commission interpret that all electromagnetic aspects relating to safety including functional safety are covered by the LVD." Many of you will be aware that a revision to the LVD is underway. At the present state of discussions the draft "essential requirements" are far more detailed than the old "safety objectives" and certainly include this issue. Of course, what the final text will be is not known with certainty at this time. Regards, Richard Hughes Personal opinions only, of course. -----Original Message----- From: drcuthbert [ mailto:[email protected]] Sent: 10 February 2003 19:27 To: [email protected] Subject: EMC-Related Functional Safety
