The previous batch's mixed-road test results serve as a reference only; this batch still has to be checked against the actual material. Urban, gradient, and unpaved-road records should share one version baseline, and when an update appears, keep the old version and explain the change. Drawing a whole-vehicle fit conclusion from a single route is a clear hold point, so do not continue payment or delivery before the correction and re-check are done. When closing the mixed-road test file, use this cross-border vehicle procurement guide to check the earlier and later records. Before shipping resumes, someone who took no part in the original work should review the mixed-road test sheet.
