The work aims to test the mechanical property of a light and environmental foam pallet for determining its rated load and evaluating its various working performances, so as to provide methods and thought for studying the performance of a new pallet. The mechanical property tests of light and environmental foam composite pallets were carried out according to ISO 8611—2011 pallet test standard. The mechanical property of this kind of composite pallet in the case of different uses was evaluated by combining the test data of different test items. The new foam composite pallet had good mechanical property in all tests. The rated loads of pallets were different in the case of different uses. The reliable data are provided for reasonably designing the pallet structure and scientifically choosing the pallet to be suitable for various logistics environments.
