IEEE 167A-1980

IEEE 167A-1980 is the IEEE Standard Facsimile Test Chart, a technical reference used to evaluate facsimile performance and image reproduction in computing and processing systems. It provides a common test target for checking how well a fax device captures, transmits, and renders detail, contrast, and alignment. For equipment designers, test labs, and procurement teams, IEEE 167A-1980 helps create more consistent comparisons and supports clearer acceptance testing. It is marked as superseded, so historical context matters when reviewing older systems.

IEEE 167A-1980 overview

This standard defines a facsimile test chart intended for objective assessment of transmission and reproduction quality. In the context of computing and processing, such a chart can help verify the behavior of components, circuits, devices, and systems involved in document imaging and transfer. IEEE 167A-1980 is useful where repeatable testing is needed to compare equipment performance under the same visual reference. The document is most relevant to legacy fax-related engineering, calibration, and evaluation work rather than modern consumer messaging workflows.

Typical use cases

The chart is typically used during facsimile equipment testing, bench evaluation, and performance comparison of image-handling devices. It can support checks of resolution, tone reproduction, registration, and overall fidelity in systems that scan, encode, transmit, or print document images. Engineers and technicians may use IEEE 167A-1980 when validating legacy communication hardware, documenting product behavior, or confirming that a device meets an expected baseline for image quality. It is also useful in service and maintenance settings where repeatable reference material is needed.

Why this standard matters

IEEE 167A-1980 matters because a common test chart reduces ambiguity in facsimile evaluation. When different teams use the same reference, results are easier to compare across designs, test sites, and production batches. That supports better compliance records, more reliable acceptance testing, and lower risk of misjudging image quality. For organizations dealing with older fax-based systems, the standard can still help preserve consistency in documentation, maintenance, and procurement decisions tied to legacy equipment.
