Includes the quality of magnetic characteristics, track layout, and a track format, used on a 130 mm (5,25 in) flexilble disk cartridge, recorded at 7 958 ftprad on one side using two-frequency recording at a track of 1.9 tracks per millimetre (tpmm) (48 tracks per inch (tpi)) intended for data interchange between data processing systems.
Cellular plastics — Determination of the coefficient of linear thermal expansion of rigid materials ...
Specifies two methods for determing the coefficient of linear thermal expansion. Method A is the preferred method, it gives a value on a large sample at a chosen temperature. Method B should be employed to obtain an average coefficient for the temperature interval between the cryogenic temperature and the ambient temperature. In an annex the test apparatures for both methods are described in…
