Specifies the characteristics of 130 mm (5.25 in) flexible disk cartridges recorded at 13 262 ftprad, on 80 tracks on each side, so as to provide physical interchangeability between data processing systems. This Standard is identical with ISO 8630-1:1987.

This part of ISO 8630 specifies the dimensional, physical and magnetic characteristics of the cartridge so as to provide physical interchangeability between data processing systems.NOTE - Numeric values in the SI and/or Imperial measurement system in this part of ISO 8630 may have been rounded off and therefore are consistent with, but not exactly equal to, each other. Either system may be used, but the two should be neither intermixed nor re-converted. The original design was made using Imperial units and further developments were made using SI units.
