Description / Abstract:
This International Standard specifies methods for determining and
expressing quantitatively the curl characteristics of unprocessed and
processed photographic film and paper in sheet, roll, or strip forms.
It specifies three measuring methods: 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.
These methods are not intended for use in determining the curl
characteristics of photographic materials during processing or drying.
