Revised Plywood Standard Now Available

(Tacoma, WA) APA – The Engineered Wood Association has announced that the Office of Standards and Services of the National Institute of Standards and Technology (NIST) has completed the revisions to Voluntary Product Standard PS 1-95 Construction and Industrial Plywood. Originally submitted by APA in 1966, and sponsored by APA ever since, the standard provides expanded and updated requirements for producing, marketing and specifying structural plywood for construction and industrial uses. PS 1, which also covers overlaid plywood panels, has undergone four revisions since its inception.

The revised standard, U.S. Product Standard PS 1-07 Structural Plywood, reflects the industry’s continuous evolution in manufacturing and end-use applications. For instance, the standard provides new overlay grade notations that reflect improvements in overlay technologies. High Density Overlay (HDO) grades are now differentiated into HDO-Concrete Form and HDO-Industrial, while MDO grades are differentiated into MDO-Concrete Form and MDO-General.

“PS 1-07 provides increased grade clarity so that producers can better serve market demands for specific attributes, such as strength, durability, reuse and finish,” said Steve Zylkowski, Director of Quality Services Division for APA.  “As manufacturers begin phasing in these changes, end-users can expect to see new grades rolling out of mills in the latter part of this year.
 

A list of the major changes follows.
