Rework of previously straightened panels is required when?

The correct choice highlights that rework of previously straightened panels is mandated when the owner's policy specifies such a requirement for repair. In the container inspection and repair process, adherence to the owner's policy is critical, as it dictates the standards and procedures to be followed for maintaining the integrity and usability of the container. If the owner’s policy stipulates that a panel must meet certain conditions or standards post-repair, then failing to rework it according to those guidelines could lead to issues regarding safety, functionality, or compliance with applicable regulations.

In this context, while considerable hammer marks, incorrect color, or changes in the original profile of the corrugation may indicate a need for rework, they may not necessarily trigger rework requirements unless explicitly stated by the owner’s policy. The emphasis on the owner’s directives underscores the importance of following established protocols in container repair and the variations that may exist depending on contract terms or operational standards.
