What does it mean for a container material to be "cracked"?

When a container material is described as "cracked," it refers specifically to the presence of a break that penetrates the entire thickness of the material. This means that the structural integrity of the container is compromised, which can lead to significant issues regarding its ability to safely hold cargo. Cracks can be caused by various factors, including impacts, stress, environmental conditions, or fatigue, and they can become pathways for corrosion or moisture ingress, further worsening the material's condition.

A crack that penetrates completely also indicates that the container may no longer be safe for use, as it could fail under load. This distinction is critical in container inspections, as identifying cracks helps in determining whether the container can still be utilized or if it requires repairs or retirement from service.
