Well, keep in mind you are talking about two different SIR methods for two
different purposes.
Method 2.6.3.7 is the most modern method for testing the effects of flux
residues, which is why it is used for J-STD-004.
Method 2.6.3.5, a copy of the Bellcore method, was designed to test the
cleanliness of board layers prior to lamination, not flux effects.

Likewise, IPC-9201A (2007), the Surface Insulation Handbook references
Method 2.6.3.7, but not 2.6.3.5.

Revision C (2010) of IPC-6012 has IPC-TM-650, Method 2.6.3.7 as an
applicable document, but not Method 2.6.3.5. Also I could find no
reference to a supersedure notice. I could not find Method 2.6.3.5 listed
anywhere I would have expected it to be.

Hi Richard
To the best of my knowledge that was called up by IPC 6012. I don't know
whether this is under review - but it should be (2007 = 5 year rule). I
will take this matter up with the group at APEX.
I suggest you apply some caution to the veracity of any data you produce,
as the method really needs to be updated. The old Bellcore GR-78-CORE was
superceded by method 2.6.3.7
Hope this helps
