C.16.RM:4.5 - Test the repaired contribution at the needed scope

Choose a comparison capable of exposing the defect the repair addresses. For computation, compare with an independently obtained result for the same mathematical input. For an omitted influence, use a relevant reference condition, intervention or already available contrast. For a claimed operating range, include the range boundary or change of behavior on which the claim depends.

Read the result through the repaired measurement relation. Propagate the uncertainty that could change the receiving answer, and use C.16.IR when compatible alternatives or an outer bound require interpretation. A closer numerical match can still leave a consequential ambiguity.

When the comparison leaves the needed answer unresolved, return to the remaining contribution. A further repair may be justified, or the useful result may be a narrower claim, a changed use or a stop. Do not expand a successful local comparison into a wider range claim without the corresponding basis.
