Can you give a more specific example of an accreditation requirement?  I 
know that labs can have things like a certified Quality Management 
System (QMS) and other processes under, say, ISO-9001 or ISO/IEC 17025.  
There's also things like NADCAP, although I wouldn't think phase noise 
measurements fit in the NADCAP bucket.

Those are mostly about record keeping and process control and 
documentation - Ultimately are you measurements traceable to some 
standard, are you reporting results in a standardized way, and so forth.

Typically, you have all your documentation, and then an independent 
assessor comes in and determines whether you meet the requirements for 
certification. They'll check to see if the way you do your work matches 
the process documentation, for instance.
