Gary,
You could probably contact Gerard O'Brien of Photocircuits for information on the /126 specs. I just saw a very informative (and very good!) presentation by him regarding the slash sheets, among other things. His presentation included information about /126 & /129.
Gerard is a member of a couple of IPC committees, and I think maybe the chairman of one of them(?), so you can probably find his e-mail on the IPC web site.
As Dewey stated, there are some additional parameters that are mandatory testing for /126 which are not specified in /26. During Gerard O'Brien's presentation, I think he said that the /126 and /129 specs are aimed more at very high reliability applications. If you are going to lead-free processes but are not doing medical/life safety/aerospace/military type applications, it is very possible that some of the other proposed slash sheets like /99 or /124 might be sufficient for what you need.

Two materials right now that are procured to /26 will meet the
requirements of /126. The main difference is the mandating of testing
that used to be optional, higher decomp temperature, max Z-axis
expansion of 3% @ 260 C., and CAF resistance testing.

Subject: [TN] /126 Specification Sheet
Good morning,
I remember seeing a reference to a /126 laminate specification sheet.
Draft
3 of IPC-4101B stops at /96. Where would I obtain a copy of this
document
or , better yet, how does this laminate differ from the /26 material.
Thanks,
Gary Camac
