Overview

ISO 3023:1995 – Cinematography - 65 mm and 70 mm Unexposed Motion-Picture Film - Cutting and Perforating Dimensions is an internationally recognized standard developed by the International Organization for Standardization (ISO). This fourth edition, published in 1995, cancels and replaces the previous version from 1988, introducing technical revisions to ensure ongoing compatibility in the motion picture industry.

ISO 3023:1995 defines the cutting and perforating dimensions for unexposed 65 mm and 70 mm motion-picture film. The standard specifically applies to safety raw stock film, as outlined in ISO 543, ensuring that films meet precise dimensional criteria for professional cinematographic production.

Key Topics

• Cutting Dimensions: Specifies the exact width and edge measurements for unexposed 65 mm and 70 mm motion-picture films, critical for compatibility with cameras, printers, and post-production equipment.
• Perforation Dimensions: Details the size, shape, and pitch of perforations required for reliable film transport, image steadiness, and uniformity across different batches and manufacturers.
• Dimensional Stability: Addresses factors such as temperature, humidity, film shrinkage, and their impact on film dimensions, supporting consistent quality during handling and long-term storage.
• Safety Film Compliance: Applies exclusively to safety raw stock as defined in ISO 543, which governs the use of non-flammable film base materials, essential for safe production and archival storage.
• Measurement Conditions: Establishes standard conditions (e.g., 23°C temperature and 50% relative humidity) under which film measurements should be performed to minimize variability.

Applications

ISO 3023:1995 plays a crucial role in the cinematography industry by providing clear technical requirements for film manufacturers, laboratories, and content producers. Key applications include:

• Film Manufacturing: Enables consistent production of 65 mm and 70 mm motion-picture film stock with standardized dimensions, essential for compatibility across global supply chains.
• Motion Picture Production: Ensures that raw camera negative and print films will interface correctly with industry-standard cameras, printers, and projectors, reducing the risk of mechanical failure or image instability.
• Post-Production & Archiving: Supports uniformity in editing, duplication, restoration, and long-term storage of motion-picture films, especially for large-format and high-definition productions.
• International Trade: Facilitates cross-border movement and interchangeability of raw stock and finished film products by aligning dimensional specifications.
• Equipment Design: Guides camera and projector manufacturers, ensuring their equipment handles film safely and reliably, based on standardized perforation and cutting dimensions.

Related Standards

ISO 3023:1995 references and aligns with other key standards in cinematography and photographic film:

• ISO 543:1990 – Photography - Photographic Films - Specifications for Safety Film: This standard defines the requirements for non-flammable safety film base materials, fundamental for compliance with ISO 3023.
• Manufacturing and Measurement Standards: For professionals working with film at critical tolerances, adherence to ISO 3023 ensures seamless integration in film systems alongside relevant equipment standards.
• Other Cinematography Standards: ISO/TC 36 (Cinematography Technical Committee) oversees a suite of standards that encompass raw film materials, processing, and equipment compatibility.

By adhering to ISO 3023:1995, industry stakeholders ensure precision, safety, and international compatibility in the cutting and perforating of 65 mm and 70 mm unexposed motion-picture film, supporting the highest standards of quality in cinematic imaging and archival preservation.

Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national Standards bodies (ISO member bodies). The work
of preparing International Standards is normally carried out through ISO
technical committees. Esch member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 3023 was prepared by Technical Committee
