This International Standard provides specifications and test procedures for establishing the safety of photographic films with respect to hazards from fire. The specifications are applicable to both unprocessed and processed¹⁾ films on any type of currently known plastic support.

These specifications cover silver films (both gelatin and non-gelatin types), colour films, diazo films, vesicular films, and striped or full-width magnetic films. Magnetic tapes and video recording tapes are excluded.

A field test for burning behaviour is described in informative annex B, and methods of marking film are defined in informative annex C. A simple test to distinguish non-safety nitrate-base film from cellulose ester and polyester-base film is given in informative annex D.

1) Normally, unprocessed and processed films have the same safety characteristics, so either one may be tested for conformance to these specifications. If an additional treatment, such as a lacquer coating, has been applied after processing, the safety characteristics may or may not be affected. In case of doubt, both unprocessed and processed films must be tested.
