I've run into this in another way at different companies. 

As soon as one version of the product hits the mfring floor 
(and thus the lab), the marketing boys come with 10 or so 
different flavors of the product which they had in mind but 
never disclosed to anyone.  In some cases, drastically 
different configurations.  At least enough to cause me 
concern in terms of not only emissions but safety as well 
(i.e. power, accessibility, ...) 

It's extremely annoying to justify going back to the lab when 
everyone doesn't want to hear it since they've concluded all 
testing of one version of a product (and thus ALL versions 
of the product) is done and finished.

Hi there,
don't think safety and EMC are incompatible.
There is an very interesting article about the matter at
http://www.iee.org.uk/PAB/EMC/core.htm
I think they go by the rule speak softly  but carry a big stick

Regards

 Hi Tania,

 Well I think the metric that should be used is
 the number of user safety related occurences of
 IT equipment..I'll bet the number is low.!!

 Having been involved in Safety for a couple of years
 I was struck by the different approaches that
 the compliance regulators adopted. To be fair
 the system level approach IS the correct approach
 for EMC - after all the final assembly is the
 mechanism that will radiate or be susceptible.
 However, the EMC industry is facing a crossroads.
 If the regulators continue to maintain the current
 methodology(like King Canute) inspite of the
 tsunami of electronic products, then I fear there
 is no future for the standards. After all there are
 many bright managers out there who will come to the conclusion that the
emissions test is voided by the
 sheer volume of product that is released and the
 inability of mnufacturers to maintain the compliance
 without crippling cost and schedule.
