Pallet Design System (PDS)

Developed and owned by:
National Wooden Pallet and Container Association (NWPCA)
eP

Research and development for early versions of PDS were conducted in cooperation with:
Pr

Center for Unit Load Design, Virginia Tech Department of Wood Science and Forest Products;
U.S.D.A. Forest Service and Forest Products Laboratory; APA - The Engineered Wood Association;
Software Technologies Laboratory, Virginia Tech Department of Industrial and Systems Engineering
The recommendations from PDS are based on the NWPCA's continuing program of laboratory and field research. They represent the best available engineering information compiled to date.
However, the quality of workmanship, the input data, and the conditions in which pallets are used may vary widely. Therefore, the Association cannot accept responsibility for pallet performance
or design as actually constructed. Wood pallets manufactured to this PDS design are for the sole purpose of storing and/or transporting material.
Th

Under no circumstance should any person stand, step, or lean upon them or otherwise use them for support.

Pallet Damage Rate Analysis

The Pallet Damage Rate Analysis simulates a series of forces and impacts applied to the pallet during each handling cycle.

d
The frequency and severity of these impacts are estimates based on laboratory measurements, warehouse observations,
and the Virginia Tech FasTrack Handling Cycle. The resistance to damage and the damage level requiring
component repair or replacement are based on laboratory testing and the NWPCA Uniform Standard for Wood Pallets.
