AIIM MS29-1992, Micrographics - Cores and Spools for Microfilm Recording Equipment - Dimensions

This standard covers the common (16mm, 35mm and 105mm widths) cores and spools currently in sue by the microfilm industry in original recording equipment. Since this is primarily a listing of already approved standards where duplication of coverage exists with another ANSI or ISO standard, the standard with narrower tolerances has been used. It is not the purpose of this document to specify materials or construction. However, since they are critical, it will be noted that although metals, plastics, and paperboard are in use, not all can be inter-substituted for all sensitized film products.

Applicable standards are listed in the event further detail or other information is needed or desired.

Spools that are an integral component of a cartridge, cassette or magazine used in microfilm recording equipment are not covered by this standard.

The purpose of this standard is to provide guidance so manufacturers of spools and cores for micrographic use.
