Abstract
The National Institute of Standards and Technology (NIST) is distributing for public comment a proposed revision of Voluntary Product Standard PS 2-25, Performance Standard for Wood Structural Panels. The revisions to the standard were coordinated by the APA--The Engineered Wood Association, (formally known as the American Plywood Association), prepared by the Standard Review Committee, and approved by the PS 2 Standing Committee. The proposed standard would establish the physical properties and structural performance criteria for assessing the acceptability of wood structural panels primarily used for construction sheathing and single floor applications and provide a basis for common understanding among the manufacturers, distributors, and users of these products. Interested parties are invited to review the proposed standard and submit comments to NIST.

Proposed Voluntary Product Standard PS 2-25, Performance Standard
for Wood Structural Panels
AGENCY: National Institute of Standards and Technology, Commerce.
ACTION: Notice of availability; request for comments.
-----------------------------------------------------------------------
SUMMARY: The National Institute of Standards and Technology (NIST) is
distributing for public comment a proposed revision of Voluntary
Product Standard PS 2-25, Performance Standard for Wood Structural
Panels. The revisions to the standard were coordinated by the APA--The
Engineered Wood Association, (formally known as the American Plywood
Association), prepared by the Standard Review Committee, and approved
by the PS 2 Standing Committee. The proposed standard would establish
the physical properties and structural performance criteria for
assessing the acceptability of wood structural panels primarily used
for construction sheathing and single floor applications and provide a
basis for common understanding among the manufacturers, distributors,
and users of these products. Interested parties are invited to review
the proposed standard and submit comments to NIST.
DATES: Written comments regarding the proposed revision, PS 2-25,
Performance Standard for Wood Structural Panels, should be submitted to
the Standards Coordination Office, NIST, no later than October 13,
2026. Written comments should be submitted according to the
instructions in the ADDRESSES section below. Submissions received after
that date may not be considered.
ADDRESSES: An electronic copy (an Adobe Acrobat File) of the proposed
standard, PS 2-25, Performance Standard for Wood Structural Panels, can
be obtained at the following website <a href="https://www.nist.gov/standardsgov/voluntary-product-standards-program">https://www.nist.gov/standardsgov/voluntary-product-standards-program</a>. This site also includes an
electronic copy of PS 2-18 (the existing standard). Written comments on
the proposed revision should be submitted to Nathalie Rioux, Standards
Coordination Office, NIST, 100 Bureau Drive, Stop 2100, Gaithersburg,
MD 20899-2100. Electronic comments may be submitted to
<a href="/cdn-cgi/l/email-protection#e99a9d88878d889b8d9aa987809a9dc78e869f"><span class="__cf_email__" data-cfemail="f88b8c99969c998a9c8bb896918b8cd69f978e">[email protected]</span></a>.
Instructions: Attachments will be accepted in plain text, Microsoft
Word, or Adobe PDF formats. Comments containing references, studies,
research, and other empirical data that are not widely published should
include copies of, or electronic links to, the referenced materials.
All submissions, including attachments and other supporting
materials, will become part of the public record and subject to public
disclosure. All comments responding to this document will be a matter
of public record. Relevant comments will generally be available during
and after the comment period closes on NIST's website at <a href="https://www.nist.gov/standardsgov/voluntary-product-standards-program">https://www.nist.gov/standardsgov/voluntary-product-standards-program</a>. NIST
will not accept comments accompanied by a request that part or all of
the material be treated confidentially because of its business
proprietary nature or for any other reason.
Therefore, commenters should not submit confidential business
information or otherwise sensitive, protected, or personal information,
such as account numbers, Social Security numbers, or any other
information they do not wish to be posted publicly (e.g., personal or
confidential business information).

SUPPLEMENTARY INFORMATION: Proposed Voluntary Product Standard PS 2-25,
Performance Standard for Wood Structural Panels, would establish
requirements, for those who choose to adhere to the standard, for
structural panels. This standard would establish the performance
requirements regarding adhesive bond performance, panel construction
and workmanship, dimensions and tolerances, and moisture content of
wood structural panels intended for construction sheathing and single
floor end uses as well as the certification and marking requirements
for panels.
The proposed revision of the standard has been developed and is
being processed in accordance with 15 CFR part 10, Procedures for the
Development of Voluntary Product Standards. The Standing Committee for
PS 2-25 is responsible for maintaining, revising, and interpreting the
standard and comprises producers, distributors, users, and others with
an interest in the standard.
After reviewing the standard, the Committee determined that updates
were needed to reflect current industry practices. The Committee held
meetings to review the standard and make needed changes.
The PS 2 Standing Committee voted on the revision, and it was
approved by 100% of the eighteen voting members. The Committee
submitted a report to NIST with the voting results and the draft
revised standard. NIST has determined that the revised standard should
be issued for public comment. Section C5 of PS 2-25 contains a summary
of significant changes.
Proposed Voluntary Product Standard PS 2-25, Performance Standard
for Wood Structural Panels, revises PS 2-18 and includes the following
changes:
1. Added definitions of Lot, Span Rating, and Veneer.
2. Added Bending Strength information in 6.4.2.1.
3. Added 3/8 Category 24/0 in Table 4.
4. Updated Figure 6 to fix the conversion of units; updated Figure
7 to fix ``mm'' that was cutoff in the image; updated Flowchart in
Appendix B by changing Small Bending to Small Static Bending.
5. Updated test procedure for Static Bending Stiffness capacity by
updating what each term in the equation refers to.
6. Updated Section 8 Marking and Certification by adding a
subsection on Accredited Certification Agency; revising Qualified
Inspection and Testing Agency subsection and adding a subsection on
Accredited Inspection Agency and a subsection on Accredited Testing
Laboratory; adding a subsection on Outsourcing (Subcontracting).
7. Added Section 9 on Quality Assurance Requirements which included
adding the following subsections Manufacturing Quality Program,
Inspection and Test Program, Sampling and Corrective Action.
The Standing Committee for PS 2-25 and NIST propose to revise the
standard accordingly after reviewing public comments. NIST will publish
a notice advising the public when PS 2-25 has been finalized.
Alicia Chambers,
NIST Executive Secretariat.
