Описание (английский):

This International Standard specifies the cutting and perforating dimensions for 16 mm motion-picture film which is perforated 8 mm Type R, as well as the width of the motion-picture film after processing and slitting. NOTE - Film perforated in accordance with this International Standard is also referred to as "double 8 mm motion-picture film".

Abstract

Overview

Key Topics

Cutting Dimensions: Defines exact measurements for the width of the 16 mm film after it is slit and processed to guarantee standardized handling.
Perforating Dimensions: Details the size, pitch, and position of the 8 mm Type R perforations on the film edges, which are essential for film transport, alignment, and steady image capture.
Tolerance Levels: Specifies allowable variances to ensure manufacturing accuracy, critical for film compatibility with cameras and projectors.
Film Width After Processing: Establishes the finished film width as 15.95 mm ± 0.03 mm, ensuring consistent film handling and equipment setup.
Low-Shrinkage Film Definition: Describes characteristics of film base materials used, particularly films that shrink no more than 0.2% under standard storage, exposure, and processing conditions.
Dimensional Stability Considerations: Addresses factors such as temperature and humidity effects on film dimensions, important for maintaining image steadiness and film handling precision.
Uniformity of Perforations: Highlights the critical importance of consistent pitch and hole margin for stable film transport and image steadiness during projection or digitization.

Applications

Film Manufacturing: Enables precise cutting and perforating of 16 mm motion-picture films for uniform production quality.
Camera Design and Operation: Allows camera manufacturers to design mechanisms compatible with double 8 mm perforation standards, ensuring smooth film transport.
Film Processing Labs: Helps processing facilities ensure accurate film slitting and maintain film integrity post-development.
Projection and Scanning Equipment: Facilitates the design of projectors and scanners to handle double 8 mm film reliably with minimal mechanical errors.
Archival and Preservation: Supports film archivists by providing standard dimensional benchmarks for film storage, handling, and restoration.
Cinematography Research and Development: Provides a technical baseline for innovation in film and digital hybrid technologies where film perforations remain relevant.

Related Standards

ISO 543 – Cinematography - Motion-picture Safety Film - Definition, Testing, and Marking: Supports ISO 486 by defining the types of safety films used in perforation standards.
Other ISO cinematography standards related to film formats and performance may complement ISO 486 for comprehensive film production and handling guidelines.
National and regional standards on film material, cutting, and equipment design often reference or align with ISO 486 to ensure global compatibility.
