Full title and description

ISO 1039:1975 — Cinematography — Cores for motion-picture and magnetic film rolls — Dimensions. This International Standard specifies the sizes and dimensional requirements for cores used with motion-picture and magnetic film rolls. The 1975 edition is a short technical specification defining nominal core diameters and related geometric details for film handling and manufacture.

Abstract

The standard establishes dimensional requirements for the cores (spools) around which motion-picture and magnetic film rolls are wound. It was published as Edition 1 in May 1975 and provides nominal sizes and tolerances intended to ensure interchangeability of film rolls and compatibility with projectors, cameras and processing equipment.

General information

• Status: Withdrawn / superseded.
• Publication date: May 1975 (Edition 1, 1975-05).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 37.060.20 (Cinematography and photographic equipment).
• Edition / version: Edition 1 (1975).
• Number of pages: 4 pages.

Scope

ISO 1039:1975 applies to the cores used for motion-picture and magnetic film rolls and specifies their principal dimensions (diameters, lengths, and datum features) so that film rolls wound on these cores will be physically compatible with recording, projection, handling and processing equipment. The scope is limited to geometric core dimensions rather than material, manufacturing methods or testing procedures.

Key topics and requirements

• Definition of nominal core diameters and lengths for common motion-picture and magnetic film rolls.
• Tolerances and permissible dimensional variation for interchangeability.
• Specification of reference surfaces, flanges or locating features where applicable.
• Compatibility considerations with film transport and winding equipment.
• Notes on application to both cinematographic (photographic) film and magnetic recording film.

Typical use and users

Users include film equipment manufacturers (cores and spools), film laboratories, film archiving and restoration facilities, cinematography technicians, and suppliers of film-handling accessories. The standard is used when specifying replacement cores, designing compatible equipment, or documenting historical/legacy film formats where consistent core dimensions are required.

Related standards

ISO 1039:1975 was later revised and withdrawn. Subsequent related editions include ISO 1039:1988 (second edition) and ISO 1039:1995 (third edition), the latter being the currently maintained edition that consolidates earlier revisions. Related ISO work under ISO/TC 36 (cinematography) covers other film format and handling standards.

FAQ

Q: What is this standard?

A: ISO 1039:1975 is the first-edition International Standard that specified the dimensions of cores (spools) for motion-picture and magnetic film rolls.

Q: What does it cover?

A: It covers the principal geometric dimensions (nominal diameters, lengths, locating features and tolerances) of film cores to ensure physical compatibility between film rolls and handling/projecting equipment. It does not specify materials or manufacturing processes.

Q: Who typically uses it?

A: Manufacturers of cores and film-handling equipment, film laboratories, archivists, restorers and anyone specifying or sourcing replacement film cores or documenting legacy film formats.

Q: Is it current or superseded?

A: The 1975 edition has been withdrawn and superseded by later editions (notably ISO 1039:1988 and ISO 1039:1995). For current requirements refer to the latest active edition (ISO 1039:1995 as the consolidated edition).

Q: Is it part of a series?

A: ISO 1039 is a single-number standard that has multiple editions (1975, 1988, 1995). It is maintained under ISO technical committee ISO/TC 36 (cinematography) and relates to other standards addressing film formats, projection and handling.

Q: What are the key keywords?

A: Film cores, spools, dimensions, motion-picture film, magnetic film, interchangeability, cinematography, ISO 1039.
