Data processing — Implementation of the ISO 7- bit and 8- bit coded character sets on punched cards
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.
The purpose is to establish certain basic requirements for the marking of steam traps, and to give recommendations for additional information markings. Has, in general, to be considered in conjunction with the specific requirements which may be agreed between the partners concerned. Specifies mandatory and optional markings for steam traps.
