It really forms a part of the base design. In a broader sense it falls under "Testing" as a product must comply with the regulations of the country it will be sold into to actually meet the design requirements. It at least deserves a mention in the post, so I will update - thanks for pointing it out.<BR/><BR/>Disposal planning is an interesting one - where does it fit in? The only way that I think disposal can only work correctly is if it is inherently built into the design, so it has to go right up there with the final concept.Duncan Drennanhttp://blog.engineersimplicity.comnoreply@blogger.comtag:blogger.com,1999:blog-31006871.post-7030868984478463522008-07-03T11:00:00.000+02:002008-07-03T11:00:00.000+02:002008-07-03T11:00:00.000+02:00Hi Duncan<BR/><BR/>I would like to know what your take is on EMC testing and certification, an important part of most electronic development, especially if you ever plan to ship products to other countries. The design part should already be covered, but there is also the step involved for interaction with certification bodies and some extra costs to development.<BR/><BR/>Other kinds of certification also comes into play when your product will be used in certain environments, eg. <A HREF="http://archive.evaluationengineering.com/archive/articles/1203emc.htm" REL="nofollow">automotive</A> (see also <A HREF="http://www.sae.org/servlets/works/documentHome.do?comtID=TEVEES15" REL="nofollow">here</A>), <A HREF="http://www.rtca.org/downloads/ListofAvailableDocs_MARCH2008_WEB.htm" REL="nofollow">aviation</A>, and <A HREF="http://webstore.iec.ch/webstore/webstore.nsf/searchview/?searchView=&SearchOrder=4&SearchWV=TRUE&SearchMax=1000&Submit=OK&Query=power%20distribution" REL="nofollow">power distribution</A>.<BR/><BR/>There is also an impotant step for larger scale production to test for product quality, which consists of <A HREF="http://archive.evaluationengineering.com/archive/articles/1100reliability.htm" REL="nofollow">HALT and HASS tests</A>.<BR/><BR/>I've noticed that you don't have a step for disposal planning (when the product physically expires and the customer wants to dispose of it). This is something for which I feel we as engineers should take more responsibility, but which is mostly neglected.Francois Cilliershttp://www.blogger.com/profile/18115076426190748110noreply@blogger.com
