Most Building Codes require that wood design meet the requirements of the "National Design Specification for Wood Construction". The N.D.S. is an ANSI standard, ANSI/AFPA NDS-2001.
The standard is developed mainly by the American Forest & Paper Association. AFPA is made up of different associations in the lumber industry. AITC APA, as mentioned by a previous reply are members of AFPA along with other groups such as the Western Wood Products Association and the Southern Forest Products Association.
I don't think there is any direct involvment between AFPA and the Forest Products Laboratory in Madision, although there maybe FPL staff member both on the ANSI commitee and the AFPA technical commitees.
Since the FPL is one of the leading wood research labs in the world,the N.D.S. is based on a lot of FPL research.
