With chart imply about the production process being observed?What would a point outside the upper or lower control limits on a statistical process control?
A point outside the control limits means the event is out of control (not necessarily out of spec). You would need to provide more info about the part, process and test being done to better understand if this is a problem and how big. In any case, a point of out control means ';pay attention to me, something has changed.';
