TPI 2 - provides procedures for testing & evaluating wood trusses designed & fabricated with metal connector plates. Destructive load tests of full scale trusses in accordance with these procedures provides a means of demonstrating that minimum adequate performance is obtainable from specific metal connector plates, various lumber types and grades, a particular truss design, particular fabrication procedures, etc.. TPI 2-1995 is referenced in UBC.

TPI 2 was first published as an ANSI Standard in 1995 (ANSI/TPI 2-1995) and later published as TPI 2 - 2002 in 2007 as a non-mandatory Appendix-E to ANSI/TPI 1-2007 Commentary.
