Technical Topic
Structural plywood and oriented strand board (OSB) produced to Voluntary Product Standard PS 1, Structural Plywood and Voluntary Product Standard PS 2, Performance Standard for Wood Structural Panels are manufactured to performance specifications that include dimensional tolerances. NIST regulations applicable to structural panels do not permit the minus 1/32-inch tolerance applied to nominal panel thickness as used in previous versions of PS 1 and PS 2.
