Important updated notice -
Please read: On July 28, 2010, the Southern Pine Inspection Bureau (SPIB) notified the industry that it was reviewing a report that testing on certain pieces of lumber fell below the expected design values assigned to the applicable visual grade determined under the In-Grade Testing Program, as published in the National Design Specification for Wood Construction.
In response to this report, SPIB reviewed its testing data during the past 17 years. Although SPIB did not find a decrease in the MOE (modulus of elasticity) in its review sufficient to trigger the next phase under the SPIB Resource Monitoring Program, it did find that further study of the matter would be prudent. As such, in November 2010, SPIB submitted a proposal to the American Lumber Standards Committee Board of Review (ALSC BOR) outlining the sampling, testing and analysis it intended to perform as part of its study.
On September 15, 2011, following this testing, the SPIB requested that the ALSC BOR approve a Supplement to the 2002 Grading Rules for Southern Pine Lumber. Please click here for a copy of this request. On October 19, 2011, the ALSC BOR deferred decision on this request for sixty days. Please click here for a copy of this deferral notice.
The ALSC BOR convened a second hearing on January 5, 2012. All interested parties were afforded an opportunity to provide comments at the hearing. The ALSC BOR issued its initial ruling on January 11, 2012, and a supplemental ruling on January 12, 2012.
In summary, the ALSC BOR approved SPIB's proposed design values changes for No. 2 and lower grades (i.e., No. 3, Stud, Construction, Standard and Utility) of 2x4 lumber with a recommended effective date of June 1, 2012. These design value changes will be applied to No. 2 and lower grades, 2" to 4" thick, 2" to 4" wide. The ALSC BOR did not approve SPIB's design value recommendations for 2x4 grades higher than No. 2, or for dimensions other than 2x4. The ALSC BOR noted that design values for these sizes and grades may not be determined by extrapolation from the No. 2 2x4 data, but will require independent testing. (Applicable resource documents are listed below.)
Although the ALSC BOR's ruling provides for future rather than immediate implementation of new design values for 2x4 lumber and the other widths requiring further testing, "it cautions all interested parties to take note of all available information in making design decisions in the interim." The ALSC BOR further advises, "All design professionals are advised in the strongest terms by the Board to evaluate this information in formulating their designs in the interim period."
