How is a splice defined in the context of container repairs?

In the context of container repairs, a splice refers to a method used to join parts of a primary structural component, thus making a permanent repair to enhance the integrity of the container's structure. This process is crucial because it ensures that the structural components, which are vital to maintaining the overall strength and safety of the shipping container, are restored effectively. By securely connecting sections of material, a splice can help restore the load-bearing capabilities necessary for safe intermodal transport.

The other options indicate different types of repairs or classifications that do not align with the definition of a splice. For instance, a splice is not merely a repair for non-structural components, nor is it limited to reinforcements attached to minor defects or temporary fixes. Understanding the definition of a splice as a permanent solution to structural inadequacies is essential for ensuring that containers remain compliant with safety regulations while maintaining their operational integrity.
