Steve,

I have a copy of the IPC-9252, and have not referenced it on any PCB
drawings.  My reasoning here is that ideally the drawing specifies only the
tests and test parameters to be performed (generally referenced in
IPC-6012), and not the procedures and/or fixturing used to complete the
required tests.  The Scope statement of IPC-9252 is as follows: "This
document is presented to assist in selecting the test analyzer, test
parameters, test data, and fixturing required to perform electrical test(s)
on all unpopulated printed boards without embedded components (i.e.,
resistors, capacitors, etc).  The users must determine the test parameters
and fixturing requirements to test for continuity (open), isolation
(leakage/short), and other special characteristics (i.e., impedance, hipot,
capacitance, current carrying capacity, etc.) that will satisfactorily
evaluate the critical electrical characteristics of specific printed boards.
The testing levels in this document define some of these parameters."  I
view IPC-9252 as a technical document used to assist selecting which tests
you want or need, and also for a better understanding of how specified tests
are performed.

My 2-cents.

Good Morning,
I've been asked to look into adding IPC-9252 "Requirements for Electrical
Testing of Unpopulated Printed Boards" to our PWB drawings.
Although we currently have electrical test requirements on the drawings that
are adequate, I'm skeptical about imposing requirements that may be
superficial.  Does anyone have experience using this document?  Is this is a
widely used standard?  Pro's and Con's are appreciated. 
Thanks in advance for your responses.

Steve
