Abstract
Overview
ISO 1154:1975, titled Information processing - Punched paper tape - Dimensions and location of feed holes and code holes, is an international standard developed by ISO to specify the physical characteristics of punched paper tape used for information processing and data exchange. The standard defines the precise dimensions and locations of both feed holes and code holes on paper tape, targeting punched paper tape with a nominal width of 25.4 mm (1 inch) and fully punched round holes. These specifications are critical for achieving reliable interchangeability and compatibility between data processing systems that use punched tape for storing or communicating digital information.
