- Scope
- This standard specifies the method for measuring and quantitatively expressing the curl properties of sheet, roll or strip photographic film and paper before and after development. This standard specifies three measurement methods: Method A is a method for measuring the degree of curl when the specimen is kept vertical. Methods B and C are methods for measuring curl when the specimen is in the horizontal position. Due to the difference in the shape and size of the sample, the values of the three measurement methods are not comparable to each other. None of the three methods can be used to determine the curl properties of photosensitive materials during processing and drying.
