# Applicability Test for Performance Targets Across Triggering Conditions

In safety-of-the-intended-functionality analysis under ISO 21448, an uncertainty threshold that keeps a LiDAR detector within a performance target under one condition had no procedure to check whether it still does under another. The threshold is transferred unchanged into the condition of use, and a statistical test decides at a stated error probability whether the target is applicable, not applicable or not determined, together with a lower bound on the independent units needed to show the target is met. On PointPillars ensembles over KITTI and nuScenes, counted in frames, the threshold transferred from nuScenes to KITTI was not applicable on all five splits; counted in recorded sequences, neither dataset held enough units to show any target limit met.
