CAUTION: Test specimen may rotate during polishing causing it to fall off chuck. Close attention should be paid to test specimen and fingers or any loose clothing, hair, badge lanyards, etc. to ensure no entanglement occurs. Stand to side of chuck while apparatus is rotating. 12 Apply abrasive cloth to test specimen and continue grinding until any rust or irregularities are removed. 13 Final polishing is performed using a new piece of abrasive cloth and is performed immediately prior to running test. q Procedure Completed Date: Prepared By: Approved By:
