American Softwood Lumber Standard PS 20

One of the main functions of the ALSC is to maintain the American Softwood Lumber Standard (Voluntary Product Standard PS 20). The current edition is PS 20-10.

The ALSC serves as the standing committee for this document. It is developed in accordance with the Procedures for the Development of Voluntary Product Standards of the U.S.Department of Commerce.

Developed through a consensus process, PS 20 establishes sizes, green/dry relationships, methods of assigning design values, industry nomenclature, inspection provisions, re-inspection provisions, and grademarking requirements.

PS 20 provides the basis for policies and procedures developed by the ALSC and enforced through the Board of Review. The American Lumber Standard system is the result of this process.

PS 20 is published by the National Institute for Standards and Technology (NIST) operating under the U.S. Department of Commerce. PS 20 is available as an Adobe pdf version.
