How do manufacturers test the load-bearing capacity of PVC sculpture joints?

Manufacturers test the load-bearing capacity of PVC sculpture joints through a series of rigorous methods to ensure durability and safety. Common techniques include static load testing, where weights are applied to the joints to measure resistance over time, and dynamic load testing, which simulates real-world stress and movement. Additionally, tensile and compression tests evaluate the joints' ability to withstand pulling and pushing forces. Advanced methods like finite element analysis (FEA) may also be used to predict performance under varying conditions. These tests help guarantee that PVC joints can support the intended weight and maintain structural integrity in both artistic and functional applications. Quality control standards, such as ASTM or ISO certifications, often guide these processes to ensure consistency and reliability.
