Overview - ISO 11928-1:2000 (Micrographics, Test Frame Characteristics)
ISO 11928-1:2000 specifies the characteristics of test frames used to evaluate the image quality of microforms produced by graphic COM recorders. The standard applies to COM recorders that output alphanumeric and graphic images onto black-and-white film. It defines test-frame layouts and measurable features to assess frame size, linearity, resolution, legibility, density, radial recording, curved-line reproduction, and character display/rotation.
Key topics and technical requirements
The standard focuses on precise, repeatable test patterns (test frames) to support quality control of microforms:
- Frame geometry and positioning
- Rectangular grid matching the recorder’s largest image size.
- Grid lines at intervals of one-eighth of the long axis from the frame centre, plus diagonals connecting corners and midpoints.
- Resolution, legibility and density
- Patterns of five-line groups with identifying letters to locate the point of resolution failure.
- Groups of lower‑case letter “e” in varying sizes, each identified by a numeral, to determine legibility limits.
- A designated area for measuring minimum optical density (may be separate).
- Radial recording
- Parallel pairs of radial lines spaced at 22.5°; separation in each pair equals line thickness - used to check radial fidelity.
- Curved-line reproduction
- Concentric circles with radial lines at 45°; outer circles drawn with double lines to assess curvature integrity.
- Character display and rotation
- Lines of characters at available character sizes and small rotated character samples in frame corners to test character rendering and rotation.
Normative references and context:
- Uses terminology from ISO 6196-7:1992 (computer micrographics vocabulary).
- Intended to help COM outputs be comparable with conventional microfilm standards such as ISO 3272-1/2/3.
Applications - who uses ISO 11928-1
- Manufacturers of graphic COM recorders and film output devices for design verification and product development.
- Quality-control engineers and test labs establishing routine image-quality checks.
- Archival and records managers ensuring COM-generated microforms meet archival standards and interoperate with microfilm systems.
- Document imaging professionals integrating COM outputs into microfilm-based workflows (e.g., aperture cards).

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. Each 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
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.
Attention is drawn to the possibility that some of the elements of this part of ISO 11928 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 11928-1 was prepared by Technical Committee ISO/TC 171, Document imaging
applications, Subcommittee SC 1, Quality.
ISO 11928 consists of the following parts, under the general title Micrographics — Quality control of graphic COM
recorders:
� Part 1: Characteristics of the test frames
� Part 2: Quality criteria and control
Introduction
This part of ISO 11928 has been prepared because increasing numbers of technical drawings are now produced
on COM, and, although their quality is usually reasonable, they are not always comparable with microfilm copies of
hard copy drawings. This can cause difficulty when both kinds of drawing are put into aperture cards and used in
systems designed to deal with microfilm copies of hard-copy-drawings.
This part of ISO 11928 has therefore been prepared to help users to establish procedures that should ensure that
the quality of COM-generated drawings is both acceptable in itself and comparable in quality with technical
drawings on conventional microfilm that complies with ISO 3272-1, ISO 3272-2 and ISO 3272-3.
