What is the maximum allowable length and width of a crack?

The maximum allowable length and width of a crack is determined based on industry standards for maintaining the structural integrity and usability of dry vans. The selection of length and width values provides specific criteria that help ensure cargo safety and compliance with loading standards.

The correct choice indicates a maximum allowable crack length of 200mm and a width of 5mm. This specification helps ensure that any cracks present do not compromise the structural integrity of the dry van, which could lead to cargo damage or safety hazards during transportation. Limiting the width of the crack to 5mm is critical for avoiding larger fissures that could develop over time, worsening the condition of the dry van.

By adhering to these guidelines, operators can maintain the functionality of the van while also meeting safety regulations. The dimensions provided in the correct choice represent a balance between allowing for minor wear and tear while preventing more significant structural issues.
