5、.1 The dried films are conditioned at 37.8C(100F)inorder to simulate service aging.This method utilizes theGardner straight-line washability apparatus as a means forcontrolled removal of the dried films.A heavily weighted padis employed as a means of arriving at a scrubbing force similarto that of h
