Past NDS editions

Where can I find more information about past NDS editions?

The first edition of the National Design Specification for Wood Construction was printed in 1944 by the National Lumber Manufacturers Association (NLMA). Revisions of the 1944 edition of the Specification were issued in 1948, 1950, 1951, 1952 and 1953. New editions were published in 1957, 1960, 1962, 1968, 1971, 1973, 1977, 1982, 1986 and 1991. The 1968 edition was the first published under the Association's new name, the National Forest Products Association (NFPA). In 1993, NFPA merged with the American Paper Institute to form the American Forest & Paper Association (AFPA).

The scope of the Specification has remained essentially unchanged since the first edition was issued in 1944. Information on machine stress rated lumber and timber piles was introduced into the 1971 edition and expanded in the 1973 edition. The name of the Specification was changed to the "National Design Specification for Wood Construction" in the 1977 edition.

The oldest design values on record with AWC are from 1922. Click here to see them.

We have archival copies of the NDS beginning with the 1944 edition. Contact the Help Desk.
