How is rear sill outward deformation measured?

The correct method for measuring rear sill outward deformation involves using a 5mm spacer. This measurement is critical in assessing the structural integrity of the dry van. A 5mm spacer allows for a standardized way to gauge deformation accurately without introducing variables that could arise from using different spacer sizes.

Utilizing a specific spacer size helps to achieve consistency in measurements across different evaluations, ensuring that the deformation is analyzed accurately. The choice of a 5mm spacer strikes a balance between being thick enough to provide a clear measurement reference while still being thin enough to allow for precise readings of minor deformations.

Other spacer sizes do not provide the same level of standardization and might lead to inaccuracies in the reading, which could misrepresent the actual condition of the rear sill. Hence, using a 5mm spacer facilitates a reliable methodology for inspection in accordance with industry practices.
