Full title and description

ISO 24537:2007 — Micrographics — Dimensions for reels used for 16 mm and 35 mm microfilm. The standard specifies the essential dimensions of lightweight reels (plastic or metal) intended for storage and retrieval of processed 16 mm and 35 mm microfilm used in manually threaded equipment.

Abstract

ISO 24537:2007 defines the critical sizes and dimensional characteristics for lightweight microfilm reels to ensure interchangeability and safe handling in manually operated devices. It explicitly excludes reels intended for automated 16 mm retrieval systems (those are covered by ISO 7761) and excludes camera spools (covered by ISO 6148).

Scope

This standard applies to lightweight reels made of plastic or metal that are used to store and retrieve processed 16 mm and 35 mm microfilm in manually threaded equipment. It does not cover reels designed for automated 16 mm retrieval systems (see ISO 7761) and does not specify camera spool dimensions (see ISO 6148). The focus is on essential external and functional dimensions that promote compatibility and safe handling across equipment and suppliers.

Key topics and requirements

• Specification of essential external dimensions for 16 mm and 35 mm microfilm reels (diameter, hub, flange interfaces and related clearances).
• Material references for lightweight reels (plastic or metal) as they affect form and functional tolerances.
• Compatibility requirements for manually threaded microfilm equipment to ensure safe storage and retrieval.
• Clear exclusions and cross-references to related standards for automated retrieval reels and camera spools (ISO 7761 and ISO 6148).
• Tolerances and dimensional controls intended to support interchangeability between manufacturers and archival users.

Typical use and users

Primary users include archives, libraries, records-management organizations, micrographics equipment manufacturers, microfilm processing laboratories and suppliers of microfilm reels. The standard helps procurement, quality control and equipment design where manual threading and mechanical compatibility are required.

Related standards

Key related ISO standards referenced by ISO 24537:2007 include ISO 7761 (dimensions for reels used in automated 16 mm retrieval systems) and ISO 6148 (dimensions for camera spools). Users may also consult other micrographics and document-imaging standards published by ISO/TC 171 for broader archival and equipment requirements.
