There’s a new 2011 revision for ASTM D6251/D6251M, “Standard Specification for Wood-Cleated Panelboard Shipping Boxes.” The 16 page document covers the fabrication and closure of empty and full wood-cleated panelboard boxes (wooden crates).
Boxes are firstly classified according to box type: Type I, Type II, Type III, and Type IV. Then they’re further segregated according to class: Class 1 and Class 2. There’s additional classification for style: Style A, Style A1, Style B, and Style C through K. And also classification according to preservative treatment; Treatment A and Treatment B. Then lastly, according to load type: Type 1, Type 2, and Type 3.
Panels using this standard are fabricated by nailing, stapling, or gluing panelboard to cleats.
Specified requirements are given for fastener component test, fastener test for securing cleats to panelboard panels, lateral resistance test, direct withdrawal resistance test, oxine copper preservative test, zinc napthenate preservative test, and preservative dryness test.
The specification has been adopted by the U.S. government as a replacement for the popular Federal specifications, PPP-B-576 (cancelled in 1998) and PPP-B-601 (cancelled in 1999).
