UL Develops Standard For Plastic Pallets.
UL 2335 consists of two fire-performance tests: an idle pallet storage test and a commodity storage test. The idle pallet test involves burning six 12-ft-high stacks of pallets beneath a sprinklered ceiling. Test parameters are the number of sprinklers activated, stack stability, time for fire to extend to the end of the array, and maximum temperature of a steel beam over the fire. The commodity storage test uses a calorimeter to measure heat release from burning pallets loaded with Class II commodities such as bottles of non-flammable liquids or non-combustible foods stored in paper or wooden containers.
UL has already tested wood pallets to obtain baseline data for comparison with plastic pallets. UL also offers a small-scale pre-test to assist manufacturers in evaluating plastic pallets before committing to the more costly UL 2335 program. The pre-test uses pallet raw material-including pellets or regrind-and a small cone calorimeter. For more information, contact Joe Hirschmugl at UL (847) 664-1508.
