What measurement condition applies to front sill outward deformation when a spacer is used?

The correct response highlights that when a spacer is utilized, the front sill outward deformation should indeed make contact with the reference line. This requirement is crucial because it ensures that the dimensions of the dry van meet specific structural integrity and safety standards. The reference line serves as a benchmark for acceptable deformation; any significant deviation from this may indicate issues with the structure's design or integrity.

In this context, touching the reference line means that the deformation is within the acceptable limits, suggesting that the dry van is functioning as intended without excessive strain or potential for failure. The maintenance of this contact provides a consistent measurement for evaluating the performance of the dry van in service.

Considering alternative responses, having the deformation exceed the reference line could imply that the dry van may be under excessive stress, which is undesirable. A flexible condition is not appropriate in this case, as it could allow for variations that could compromise measurement reliability. Finally, an adjustable position above the reference line does not align with the standard criteria that necessitate consistent contact with the reference line to ensure appropriate deformation levels.
