This standard specifies the physical and performance characteristics of cartridges used for storing and viewing processed 16 mm microfilm. The intent of the standard is to achieve compatibility between the cartridge and automatic threading readers and reader-printers. Accordingly, the standard addresses those physical features which interface with readers required to assure multireader usage. Also the winding of the processed microfilm on the reel and the physical characteristics of the leading end of the film are standardized to ensure proper interfacing of the cartridge with all readers of this type.
This standard should be used as a basis of design for future automatic threading readers and reader-printers to ensure that they accept the cartridges and film they contain over the full range of tolerances specified.
