Full title and description

ISO 1020:1974 — Cinematography — Spools, daylight loading type for double‑8 mm motion‑picture cameras — Dimensions. This International Standard specifies external and internal dimensions, gauging and spindle hole details for daylight‑loading spools intended for double‑8 mm Type R motion‑picture film (nominal capacities 7.5 m / 25 ft, 15 m / 50 ft and 30 m / 100 ft).

Abstract

ISO 1020:1974 defines dimensional requirements and features (flanges, gauging dimensions, spindle splines and arrangements) for daylight‑loading spools used in double‑8 mm cameras. The document is short (diagrams and dimensional tables), intended to ensure interchangeability and correct mounting of spools and spindles between cameras, projectors and related accessories. The standard was published in 1974 and later withdrawn; Russian‑language PDF versions and reprints have been offered by standards distributors.

Scope

The standard applies to daylight‑loading spools for double‑8 mm Type R motion‑picture film with nominal capacities of 7.5 m (25 ft), 15 m (50 ft) and 30 m (100 ft). It specifies flange and hub dimensions, gauging dimensions, and the form of spindle holes (including 3‑ and 4‑splined patterns) to ensure mechanical compatibility with cameras and spindles; it notes that high‑speed camera spools may require more careful balancing and are not necessarily covered.

Key topics and requirements

• Dimensional drawings and tolerance tables for daylight‑loading spools (flange diameters, hub widths, gauging points).
• Specification of nominal spool capacities for double‑8 mm Type R film (7.5 m, 15 m, 30 m) and equivalent feet values (25 ft, 50 ft, 100 ft).
• Details for spindle‑hole configurations including 3‑ and 4‑splined holes to match camera/projector spindles.
• Gauging dimensions and features to ensure interchangeability between manufacturers.
• Notes on balancing and special considerations for high‑speed camera spools.

Typical use and users

Used by camera and projector manufacturers, film equipment designers, restoration laboratories, archives, film‑format adapters and specialist suppliers of motion‑picture consumables. Collectors and technicians working with vintage double‑8 mm cameras may consult the standard (or a translated PDF) when producing or checking replacement spools and adapters.

Related standards

Standards referenced or related to film dimensions and handling include ISO 486 (perforation and cutting for 8 mm and 16 mm film referenced in the standard), and later/parallel cinematography standards produced by ISO/TC 36 (for example, standards on projection film leader, storage/handling and multichannel sound records). Users should consult the current ISO catalog for updated or successor cinematography standards.

FAQ

Q: What is this standard?

A: ISO 1020:1974 is an ISO specification giving dimensional requirements for daylight‑loading spools used with double‑8 mm (Type R) motion‑picture film.

Q: What does it cover?

A: It covers external and internal spool dimensions, gauging points, spindle‑hole (spline) forms, and nominal spool capacities (7.5 m / 25 ft, 15 m / 50 ft, 30 m / 100 ft), plus notes on balancing for high‑speed spools.

Q: Who typically uses it?

A: Camera and projector manufacturers, restoration shops, archives, specialist suppliers of spools and adapters, and technicians working with vintage double‑8 mm equipment. Distributors of historical standards or language translations may supply PDF copies for reference.

Q: Is it current or superseded?

A: ISO 1020:1974 has been withdrawn (withdrawal action recorded in ISO records and withdrawn from some national listings). Users should not treat it as an active current ISO recommendation; consult current ISO/TC 36 outputs and later cinematography standards for up‑to‑date requirements. A withdrawal action was recorded by ISO and national bodies (withdrawn listings noted from 2006).

Q: Is it part of a series?

A: It is a standalone dimensional standard within the cinematography group of ISO standards (ISO/TC 36). Other related cinematography standards (storage, leaders, sound records, perforation standards) form the broader set of ISO cinematography publications.

Q: What are the key keywords?

A: double‑8 mm, Type R, daylight‑loading spool, spool dimensions, spindle spline, ISO 1020:1974, cinematography, withdrawn, Russian PDF.
