There seems to be some hysteria regarding "lab generated"
DoC's.

If a third party lab is acting as signatory, I agree in
principle with the statements made on the list, but such
actions have no value to a lab and only represent a
potential legal quagmire.

Since the DoC is legally binding (perhaps the wrong term)
document that could have monetary and other ramifications,
I can't imagine a third party lab wanting to put their neck
on the block.  Labs typically have no input into a
customer's engineering change processes, purchasing
agreements, spot procurement, manufacturing floor changes,
100% or production surveillance, etc.

Safety certification labs, for instance, that provide
"listing and marking services" typically perform quarterly
product audits, others annually.  EMC is a whole other bag
of gotchas, since component selection criteria is often
critical to compliant performance.

Many labs, however, will provide a template form DoC for
customers to sign.  This is a service for inexperienced
companies who need a leg up.  It is not the same as acting
as signatory.
