Kevin and Lou,
Thank you for your inputs. I do have a copy of rev A that I just
finished reading and fully agree with your synopsis. This document
should be used as a guide in developing the test requirements for a
given PWB.
Have a great day!
Steve

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.

Subject: [TN] Inquiry on IPC-9252
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.
