適用范圍：1.1 This standard prescribes the method for determining quantitatively the brittleness of photographic film.1.1.1 This test is not a universal brittleness test for all films in all possible applications. In a particular situation the test may not correctly rate films for brittleness, and some special test may have to be devised to duplicate the particular type of stress encountered.1.1.2 The method is applicable to film with or without a gelatin backing, and may also be applied to either raw or processed film, although the brittleness level of a given film may be quite different after processing from that before processing.
