Introduction
Although the current situation is not in accordance with this standard manufacturing film it is very rare, if once that happens, there will be a lot of insecurity gum
Sheet stored in libraries and archives due to improper handling of fire risk, long-term storage under hazardous conditions, there is a danger of spontaneous combustion
Insurance, and rapid combustion characteristics, therefore, the owner of the film to provide a measurement of their film is "safety photographic film" approach is
Necessary. This is the purpose of this standard.
