What testing standards are used to evaluate the mechanical strength of WPC outdoor trash cans?

To ensure WPC (Wood-Plastic Composite) outdoor trash cans can withstand harsh conditions and public use, their mechanical strength is evaluated against specific international standards. Key standards include ASTM D7031 for wood-plastic composite products, which outlines tests for properties like stiffness and impact resistance. Load testing, often following principles from standards like ASTM D1185 for containers, assesses the trash can's ability to hold weight without deforming. Impact resistance is crucial; methods similar to ASTM D5420 (for plastic profiles) evaluate resistance to sudden blows. Additionally, long-term durability under load (creep resistance) and weathering tests (like ASTM D6662 for UV resistance) are vital. These standards collectively ensure the product's structural integrity, safety, and longevity in outdoor environments.
