I read in !emc-pstc that cherryclo...@aol.com wrote (in <131.6a66623.296 70...@aol.com>) about 'EMC-related safety issues', on Fri, 4 Jan 2002: >As I recall, the EU's Product Liability Directive (85/374/EEC amended by >99/34/EC) requires manufacturers to produce products that are: "as safe as >people generally have the right to expect".

How do you decide what tests to do **for weaknesses you don't suspect**? Isn't that fundamentally impossible? >And yes, you must consider foreseeable misuse and stupid users too. (The >trouble with trying to make something foolproof is that fools are so >ingenious!) Exactly! Is replacing the mains fuse in a product with a bit of fencing wire 'foreseeable misuse'? I have put this question to an IEC safety committee; it's not just a debating point! > >Then hopefully you won't ever find yourself trying to defend your design >decisions in a court of law. Hopefully! Will your CEO accept that 'hopefully' your design won't put him in jail for corporate manslaughter? But can you ever give a better assurance than 'hopefully', at the necessary 1 in a billion probability level? I think not. >Also, your company's exposure to significant financial and commercial risks >will be reduced - this is the key to justifying the expense of good safety >design to your employers. But it seems that the expense of 'good safety design', as determined by some safety experts, is going through the roof. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero. ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
