35.220.10 - Paper cards and tapes

Defines implementation of ISO 7-bit and 8-bit coded character sets on punched cards as well as the representation of 7-bit and 8-bit combinations on 12-row punched cards. This representation is derived from, and compatible with, the Hollorith Code. Ensures widely compatibility with existing punched card files. Intended for general interchange of information among data processing systems.

Provides representation of 7-bit coded character set on punched tape 25,4 mm (1 in) in width. Applicable in conjunction with ISO 646, 1154, 1729.

Lays down the dimensions of take-up (or storage) reels with separable flanges, and of cores, so that rolls of perforated tape may be interchanged among machines of various manufacturers. It is also intended to serve as a guide in the coordination of equipment design. A compatible reel and core are described. These can be used together or either one can be used separaterly to transfer tape from one machine to another.

Establishes dimensions and location of feed holes in punched paper tape for data interchange. Applies to punched paper tape with a nominal width of 25,4 mm with fully punched round holes.

Defines the characteristics of general-purpose unpunched paper cards to be used information interchange between different punched card devices. References: ISO/R534; ISO/R 536; ISO/R 1974; ISO/R 2144; ISO 2493; ISO 2494; ISO 2758.
