IEEE 167A.2-1996

IEEE 167A.2-1996 is a facsimile test chart standard for high-contrast gray scale testing in communication, networking and broadcast technologies. It defines a practical reference for evaluating how fax and related imaging systems reproduce tonal steps, contrast transitions, and overall image clarity. IEEE 167A.2-1996 is useful when consistent test input is needed to compare device performance, support calibration, or confirm that facsimile equipment handles grayscale detail in a repeatable way.

About IEEE 167A.2-1996

This standard addresses a specific facsimile test chart designed for high-contrast gray scale applications. Its technical value lies in providing a controlled image target that can be used to assess how transmitting and receiving equipment handles density changes and tonal separation. In practice, IEEE 167A.2-1996 helps create a common basis for testing and comparison, especially where image fidelity and contrast behavior are important to system evaluation and documentation.

Where is IEEE 167A.2-1996 used?

IEEE 167A.2-1996 is most relevant in facsimile test environments, imaging verification workflows, and equipment qualification work tied to communication and broadcast systems. It may be used by laboratories, service organizations, and manufacturers that need a consistent gray scale chart for checking transmission quality, scanner response, or print reproduction. The standard supports controlled testing where image contrast and tonal visibility must be reviewed against a known reference.

Importance in practice

In practice, the standard helps reduce variation in facsimile testing by giving engineers and technicians a stable reference for evaluation. That can improve consistency during design checks, procurement comparisons, and maintenance verification. By using IEEE 167A.2-1996, organizations can better judge whether equipment meets expected performance for grayscale reproduction and contrast handling. This lowers the risk of ambiguous test results and supports more reliable technical decisions.
