Zusammenfassung:	The testing of an article for deviations thereof from an optimum thickness range includes scanning the article by means of a thickness measuring device; making a plurality of thickness measurements of the article during each scan; averaging successive groups of a predetermined number of theoretical measurements during each scan; comparing the averages so obtained with predetermined desired averages and marking a visual record with symbols indicative of whether each group is within, greater than, or less than the desired average.
