There are huge differences between PVA adhesives. As far as the
"tests" go, you can throw them out the window.  They were done by
Norbert Baer at the NYU conservation center over 30 years ago, and
reprinted by the Guild of BookWorkers during that era.  It was very
useful info at the time.

I saw Dr. Baer at the Grolier Club a few years ago and asked him
whether those results were still valid. He said that the
manufacturers had changed formulas many times since then, and did not
disclose the changes. Some of the manufacturing companies had changed
hands as well. He advised not to rely on the old data.

I use Jade 403 for general purposes, but use Promacto A1023 for
boxmaking because of its high tack and fast set.
