Proof load testing is a critical process used to verify the strength and performance of a structure, component, or system under specified loads. This testing ensures that the item can safely carry its maximum intended load without experiencing failure or permanent deformation. Commonly used in industries such as construction, manufacturing, and shipping, proof load testing involves applying a load higher than the expected working load to demonstrate the safety margin. The process uses precise equipment and methodologies to validate design specifications and compliance with industry standards, ensuring the reliability and safety of products and structures in real-world applications.
