Card hole patterns assigned to the bit combinations of 7-bit and 8-bit codes.

This International Standard defines the implementation of the ISO 7-bit and 8-bit coded character sets on punched cards. It specifies the representation of 7-bit combinations and 8-bit combinations on 12-row punched cards. This representation is derived from, and compatible with, the code known as the “Hollerith Code??. It will ensure compatibility with a large proportion of existing punched card files.

This International Standard does not specify any redundancy nor does it define techniques for error control.

This International Standard is intended for the general interchange of information among data processing systems, when using the ISO 7-bit or 8-bit coded character sets on 12-row punched cards as data carrier.
