Which criterion is necessary for the repair of corner fittings?

The necessity for the repair of corner fittings is determined by several factors that directly impact the functionality and safety of the container. Corner fittings are critical components that play a vital role in securing the container to handling equipment and ensuring structural integrity during transport.

When corner fittings are cracked, structural weaknesses can develop that may jeopardize the container's ability to withstand the stresses of transportation. This cracking can lead to failure during handling or while the container is being loaded or unloaded.

If corner fittings are missing, this creates a significant safety concern. The absence of these fittings can prevent proper securement to container ships, trucks, or train cars, which could lead to accidents or damage during transit.

Damage that affects securement refers to any impairment that prevents the proper attachment of the container to handling equipment. This could include distortion or severe wear that compromises the fittings' ability to hold the container securely in place.

Therefore, all of these criteria—cracking, missing fittings, and damage affecting securement—are critical indicators that necessitate the repair of corner fittings. Addressing any one of these issues is essential to ensure the container's safety, functionality, and compliance with transport standards.
