ASTM D1185 defines six pallet test methods producing standard capacity ratings: static compression (max apparent load), dynamic compression (vibration/transit), racking (supported on ends only), fork-lift handling, sling handling, and inclined impact. Standard 48x40 GMA stringer pallets test at 4,600 lbs static / 2,800 lbs dynamic / 2,800 lbs racked. Block pallets typically test 5,500 lbs static / 3,800 lbs racked. Recycled Grade A pallets test 3,500 lbs static, Grade B 2,200 lbs. Heavy-duty industrial pallets can test up to 8,000+ lbs static. Specify ASTM D1185 ratings in your RFQ to ensure capacity match.
