I can't speak to the EMC standards as I am a safety engineer but I have found that most changes/ amendments in safety standards, i.e. Audio/Video IEC60065 and ITE IEC60950 tend to be either relaxation of the requirements or clarifications based on user input to the various Agencies who populate the standards committees. In my experience I did not find the amendments that happen each year or so to the above safety standards as a bad thing or present a moving target as I believe they had little or no negative impact on product designs......
If you are talking UL safety standards I think you have a case as there have been several mid stream amendments in the UL6500 standard which made the requirements more stringent which impacted our designs requiring engineering work to comply...But in UL's defense they did make our products safer so this is not a complaint but a statement in fact.....Of course this added extra cost to the products so not everyone was happy......... EMC on the other hand may be a different kettle of fish??

But my point is that the purpose of a standard is to standardize. If the standard is a constantly changing target, the point of standardization is lost, or at least severely diminished. To paraphrase an old saw, "There comes a time in the life of every program to shoot the engineers and start production." I'm not advocating shooting anyone, but if the cycle time were limited to no less than five years, maybe there would be time to get the kinks out before the next revision. > From: John Woodgate <[email protected]> > Date: Wed, 11 Jan 2006 20:48:35 +0000 > To: [email protected] > Subject: Re: Making Standards Free, different take > > In message <bfeac273.354a9%[email protected]>, dated Wed, 11 > Jan 2006, Ken Javor <[email protected]> writes >> My comment was limited to EMC and product safety.
