There
is no variation in magnification aids requirements in J-STD-001 based upon class
of product. The requirement is defined in Paragraph 11.2.2.1 and Table
11-2 as a process requirement as indicated by the reference to Paragraph 1.4 and
thus applies to all classes.
The
closest you will come to variation in requirements by class might be the
application of detail requirements (or not) as imposed by MIL-STD-2000. General
requirements defined magnification aids differently than that those of the
Detailed Process requirements of Paragraph 5.4. If you are interested in
the actual references, give me a buzz and I will forward the criteria. There was
not a class distinction in the MIL STD since the requirements applied to product
produced for the specific contract as expressed. The Detailed Tasks were
required to be called out in contract to be imposed. Otherwise the default was
General requirements and what might be considered lesser requirements.
DOD-STD-2000 had about the same concept but the criteria varied as developed in
contract between Volume 4 (General Requirements) and Volume 1,2,3 (Detail
Requirements).
Good
luck and I hope this helps.

I have a question concerning the magnification
power based on the width/diameter of the land. Has it ever been stated in an
IPC document that magnification was based on the class of product? Does anyone
know if any of the mil stds. ever stated this?
Thanks,
