Basic environmental testing procedures - Part 3-2: Background information - Combined temperature/low...
Gives background information for Test Z/AM: Combined cold/low air pressure tests (IEC 68-2-40), and Test Z/BM: Combined dry heat/low air pressure tests (IEC 68-2-41).

Describes a 9-track, 8 rows per mm (rpmm) (200 rows per inch (rpi)) 12,7 mm (0,5 in) wide magnetic tape for interchangeability of tape between information processing systems which utilize 7-bit coded character set, specified in ISO 646. Refers solely to magnetic tape for digital recording, on which the direction of magnetization is nominally longitudinal as opposed to nominally transverse.
