ISO 18908:2000

Imaging materials — Photographic film — Determination of folding endurance

This International Standard specifies a method for determining and quantitatively expressing the folding endurance

of photographic film. The method is based on the MIT folding-endurance tester described in annex B. It is an

analytical test and is not intended to simulate practical use conditions.

This International Standard is applicable to film with or without a gelatin backing. It may also be applied to either

raw or processed film, although the flexibility level of a given film can be quite different after processing.

Equipment similar to that described in this International Standard may be used provided that a correlation has been

established between the results obtained using such equipment and the results obtained using the equipment

described.
