Specifies three measuring methods for determining and expressing quantitatively the curl characteristics of unprocessed and processed photographic film and paper in sheet, roll, or strip forms: method A involves the determination of curl when the specimen is held in a vertical position, methods B and C with the specimen in a horizontal position. Values for the three methods are not comparable because of the differences in specimen configuration and size. The methods are not intended for use during processing or drying.
