Full title and description

St ISO 1729-1973 — Information processing — Unpunched paper tape — Specification. International Standard that specifies the physical and dimensional characteristics, mechanical properties and marking/coiling requirements for unpunched paper tape used for data interchange (Russian-language edition / distribution noted separately).

Abstract

Specifies requirements for unpunched (blank) paper tape intended for information-processing interchange: dimensions, tolerances, strength and tear resistance, surface quality, marking of coils, coiling and packing, and a sampling method for testing. The standard was published as ISO 1729 in December 1973.

General information

• Status: Withdrawn (standard lifecycle shows withdrawal).
• Publication date: December 1973 (Edition 1, 1973-12).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 35.220.10 — Information processing (paper tape/media).
• Edition / version: Edition 1 (ISO 1729:1973).
• Number of pages: 15 pages.

Scope

Defines the characteristics and minimum requirements of unpunched paper tape when supplied in the unpunched condition for use in information-processing equipment and interchange. It covers dimensional specifications (width, holeless margins), mechanical properties (tear and tensile strength), surface quality, coil marking and coiling practice, packing and a method of sampling for testing. The standard is intended to be used in conjunction with related punched-tape and character-set standards for data interchange.

Key topics and requirements

• Dimensional requirements: nominal widths and tolerances for unpunched tape and coil dimensions (inner/outer diameters).
• Mechanical properties: minimum internal tear resistance and static tensile strength criteria.
• Surface quality: limits on spots, pinholes, translucency, lint and dust to ensure reliable handling and recording.
• Coiling and marking: requirements for coil winding, colour of end markers, unmarked lead lengths and coil tightness to prevent telescoping.
• Sampling and testing: an annexed method of sampling a lot of coils for conformance testing (based on ISO/R paper sampling practice).

Typical use and users

Historically used by manufacturers and suppliers of information-processing media and tape-handling equipment, system integrators, archival institutions and organisations maintaining legacy data archives or museum/heritage computing equipment. Today the standard is mainly of historical or archival interest because modern data interchange uses electronic and magnetic media.

Related standards

Related information-processing and punched-tape/media standards include ISO/R 1974 and ISO 2144 (referenced for use with this document), and other contemporaneous standards on punched paper tape, coded character sets and graphical representations (examples appearing alongside ISO 1729 in historical listings include ISO 1154, ISO 1113, ISO 2047 and related NATO/STANAG references). These provide complementary requirements for punched tape dimensions, 7-bit coding and control-character representation.

FAQ

Q: What is this standard?

A: ISO 1729:1973 is an International Standard titled "Information processing — Unpunched paper tape — Specification" that defines physical, mechanical and handling requirements for unpunched paper tape used in data interchange.

Q: What does it cover?

A: It covers tape widths and tolerances, strength and tear-resistance requirements, surface quality, coiling and marking of coils, packing and a method of sampling a lot of coils for testing. It was intended to be used with related punched-tape and character-set standards.

Q: Who typically uses it?

A: Originally: media and tape manufacturers, operators of punched-tape equipment, system integrators and interoperability testing organisations. Today: archivists, museums, heritage computing specialists and standards researchers.

Q: Is it current or superseded?

A: ISO 1729:1973 is listed as withdrawn in the ISO lifecycle. It is not an active current standard and has been superseded in practice by modern data-storage and interchange media standards; consult ISO and national catalogues for the formal withdrawal/supersession record.

Q: Is it part of a series?

A: It forms part of the historical family of ISO information-processing media standards (paper tape, punched cards, magnetic tape and character-set standards) but is not a "part" of a single multipart series; it is cross-referenced with contemporaneous punched-tape and character-set documents.

Q: What are the key keywords?

A: Unpunched paper tape, paper tape specification, data interchange, tape coiling, tape mechanical properties, tape sampling.
