IMAGING MATERIALS - PROCESSED PHOTOGRAPHIC FILMS - METHODS FOR DETERMINING SCRATCH RESISTANCE
12-01-2013
Defines two test methods for evaluating the scratch resistance on either the emulsion or the base side. The two test methods usually give comparable results. It provides empirical laboratory tests made under controlled conditions, but does not necessarily predict the actual scratch resistance of a film in any particular commercial machine. Applies to evaluating the scratch resistance of dry processed photographic film.
