Report of the Standards Committee

Proposals have been received from the ISA Secretariat for International Standardization of raw-film cores; 16-mm sound-film; projection reels; projection reel boxes; 8-mm film dimensions; and definition and marking of safety film. — Most of these proposals differ from the SMPE standards only in tolerance. Some of the tolerances appear to be unimportant and some important. The European practice for projection reels differs so widely from the American practice that it is deemed impossible to come to an international agreement. Standardization of 16-mm projection reel boxes appears to be outside the range of useful standardization. — The international standard definition of safety film has been cleared up in all points except the question of nitrogen content. — The question of sound-track dimensions for 35-mm and 16-mm film was clarified, to a considerable extent, at the Hollywood meeting of the Committee but no definite conclusions have yet been reached. — No satisfactory standard for 16-mm sound-film sprockets has yet been attained.
