Dig a little deeper. ICC-ES doesn't do testing. It's all paper-pushers. Go to their offices sometime and ask to see the test lab. Closest thing they have is a kitchen. So, how reliable is the rest of your post?
Not very.
ICC-ES is camping onto a legacy that is not theirs. ICC-ES is part of ICC. ICC was formed in 1995. ICC-ES was built out of pieces of the legacy code organizations (see quoted material from ICC below).
So if years matter, as you suggest, then TPI and AWPA are the go-to guys. Not ICC-ES. Note: ICC-ES uses AWPA references quite liberally as do the I-Codes (read the ECOB ES report you posted if you don't believe me). Same for the AC. So, if you going to slam AWPA, you are tainting those that are using their specs for profit, such as ICC and ICC-ES.....and ECOB, though ECOB has been ordered to stop. (Longvester is correct on that point)
History
The International Code Council (ICC) was established in 1994 as a non-profit organization dedicated to developing a single set of comprehensive and coordinated national model construction codes. The founders of the ICC are Building Officials and Code Administrators International, Inc. (BOCA), International Conference of Building Officials (ICBO), and Southern Building Code Congress International, Inc. (SBCCI). Since the early part of the last century, these non-profit organizations developed three separate sets of model codes used throughout the United States. Although regional code development has been effective and responsive to our country’s needs, the time came for a single set of codes. The nation’s three model code groups responded by creating the International Code Council and by developing codes without regional limitations; the International Codes.
