You're probably correct but it sounds like you could be correct
without a customer. We all select components based upon our needs. The
component that most meets those needs, obviously, is the one that gets
selected first. If no other choice exists then I would look at what COULD be
made useful. From those choices I would begin selecting from those folks
that would agree to have it covered under the standard I needed. This is
not laziness its just pragmatic. Who is going to know more about the product
and have the needed documentation, second source vendors for critical parts,
trace layouts, voltage maps, or whatever else might be necessary for the
evaluation. Trying to work through a vendor to get information from them
adds significant time, effort and confusion to the process.
After it all gets done you may then be locked contractually into
providing the PCB exactly as built when investigated. That can limit your
ability to add second sources, board revisions, or even cost reduction, and
you'll end up with a non-standard part in your system as you implement those
kinds of changes and are forced to change part numbers rather than simple
rev changes.
You might want to consider performing the evaluation while charging
the customer a NRE charge to cover the time and cost. You even end up with a
wider product range than you had before. If the volume isn't there or any
other reason you don't want to sell the board, then I would stick with your
current position.

Hi everyone,
I was wondering if I have a PCB that could be used in a medical device as
well as in a PC does the board have to be tested to both standards. I
believe that it has to be tested only for ITE equipment, and the
manufacturer of the ISM device would have to comply to the iSM standard. Is
this correct?
Thanks in advance,
