This Standard defines specifications and test procedures for establishing the safety of photographic films with respect to hazards from fire. The specifications covers both unprocessed and processed films on any type of currently known plastic support. These specifications applies to silver films (both gelatin and non-gelatin types), colour films, diazo films, vesicular films, and striped or full-width magnetic films.

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 annexB, and methods of marking film are defined in informative annexC. A simple test to distinguish non-safety nitrate-base film from cellulose ester and polyester-base film is given in informative annexD.
