Rationale

In an effort to resolve questions around the development of design values for tension parallel to grain when this property is not tested, a series of ballots to ASTM D2555 and D245 have been issued. After much further discussion, the Section agreed that D245 should indicate that Practice D245 is presently used primarily for the derivation of design values for larger members and that D1990 is the preferred method for developing design values for dimension lumber. This ballot adds this statement in a new Section 1.2, and includes D1990 in the list of referenced documents.
