Full title and description

ISO 10549:2000 — Micrographics — A6 size aperture cards. This International Standard defines the physical characteristics, materials and test methods for A6-size aperture cards used to store and handle 35 mm microfilm chips; it covers opaque, translucent and transparent-film (simulated aperture) card types and gives dimensional, material and defect criteria for interchange, handling and storage.

Abstract

ISO 10549:2000 specifies dimensions, construction details and test requirements for A6-format aperture cards used in micrographic applications. The standard aims to ensure compatibility between cards, readers and handling/storage systems by standardizing card grain direction, card thickness, corner and edge treatment, aperture location, build-up limits (for adhesive and suspension types) and acceptable defects. Annex A gives additional information on transparent film card characteristics.

Scope

ISO 10549:2000 applies to A6-size aperture cards intended to contain a chip of 35 mm microfilm (recorded in accordance with related microfilming standards). It covers the physical characteristics of cards (dimensions, grain/machine direction, thickness), permissible defects, preferred corner shapes, edge treatment, aperture location and construction differences between adhesive-type (opaque or translucent) cards and suspension/jacket-type cards. It also provides limits for build-up thickness caused by adhesives or support sheets and includes informative guidance on transparent film cards with simulated apertures. The standard is intended to support interchangeability and reliable handling with readers and automated retrieval equipment.

Key topics and requirements

• Defined overall dimensions and tolerances for A6-size aperture cards to ensure compatibility with readers and filing equipment.
• Specification of grain (machine) direction and recommendations for card handling and storage.
• Limits on card thickness and build-up for adhesive and suspension (jacket) types to avoid jams and ensure proper seating of microfilm chips.
• Requirements for aperture location and permissible deviation to ensure accurate framing of the microimage.
• Definitions of acceptable defects (tears, delamination, warping) and quality criteria for production.
• Guidance on transparent-film cards (simulated aperture) characteristics provided as informative annex material.

Typical use and users

Users: archival institutions, libraries, museums, governmental record offices, engineering and architectural drawing archives, micrographics producers and suppliers, and organizations that maintain long-term microfilm-based records or migration workflows. Typical use: specifying and procuring A6 aperture cards, manufacturing and quality control of aperture cards, ensuring interchangeability with aperture-card readers and automated handling systems, and establishing storage/handling procedures for microform collections.

Related standards

Standards commonly referenced together with ISO 10549 include ISO 3272 (microfilming of technical drawings and aperture card film formats and recording), ISO 6199 (photographic film characteristics for microfilms), and ISO/BS standards on barcodes and handling for aperture cards (examples: standards on use of bar codes on aperture cards). National adoptions (identical or derived) include NEN ISO 10549:2001 and various national implementations.

FAQ

Q: What is this standard?

A: ISO 10549:2000 is an International Standard that specifies the physical characteristics and test requirements for A6-size aperture cards used in micrographics (cards that carry a 35 mm microfilm chip).

Q: What does it cover?

A: It covers card dimensions and tolerances, grain/machine direction, thickness and build-up limits, aperture location, acceptable defects, and differences between adhesive and suspension (jacket) card constructions. It also includes informative material on transparent-film (simulated aperture) cards.

Q: Who typically uses it?

A: Archivists, libraries, record managers, micrographics manufacturers and suppliers, engineering and architectural archives, and any organization that preserves or exchanges microfilm-based records.

Q: Is it current or superseded?

A: ISO 10549:2000 has been withdrawn by ISO (stage: Withdrawal of International Standard). National catalogues and standards resellers list it as withdrawn; users should check national standards bodies for any replacing or successor documents or relevant newer standards for micrographics and electronic archiving.

Q: Is it part of a series?

A: It is part of the micrographics/document-imaging family of standards developed by ISO/TC 171 (Document imaging applications) and is commonly used alongside related ISO standards such as ISO 3272 and ISO 6199. Some countries issued national identical adoptions (for example NEN ISO 10549).

Q: What are the key keywords?
