The IICL recommends a reference dimension for an outward bow in a side panel to be?

The recommended reference dimension for an outward bow in a side panel, as established by the IICL, is 18 mm (11/16 in). This specification is important to ensure that containers maintain their structural integrity and functionality. An outward bow can affect the fit of the containers, especially when they are stacked or stored, potentially leading to issues such as improper sealing or increased wear on the panels.

In container inspection practice, adhering to the IICL's recommended measurements helps inspectors identify potential problems early and ensure containers are safe for use. By setting a standard at 18 mm, the IICL aims to minimize the risk of structural defects that could compromise the container's usability and safety. This dimension is grounded in ensuring containers can withstand various stresses encountered during transportation and storage while maintaining the integrity necessary to protect cargo effectively.
