IEEE 106-1972

IEEE 106-1972 is a technical standard for test procedures for toroidal magnetic amplifier cores, including core material data. It focuses on how these magnetic components are evaluated in power, energy, and industrial applications where consistent performance matters. By defining a common testing approach, the standard helps engineers compare core behavior more reliably and supports more controlled design and procurement decisions for magnetic amplifier systems.

IEEE 106-1972 overview

This standard sets out a structured procedure for testing toroidal magnetic amplifier cores and for handling related core material data. In practice, that means it is concerned with how core characteristics are measured and reported so results can be compared across suppliers, batches, or designs. As an inactive IEEE 106-1972 document, it remains relevant for legacy equipment, technical reference work, and review of earlier magnetic amplifier practices in components and systems engineering.

Typical use cases

IEEE 106-1972 is typically useful when specifying or evaluating toroidal cores for magnetic amplifiers used in control and power-related circuitry. It may support laboratory test work, incoming material verification, and component selection for older industrial control equipment, power conditioning assemblies, or specialty magnetic devices. The inclusion of core material data makes it especially helpful where material properties must be compared alongside test results to support consistent performance expectations.

Why this standard matters

For manufacturers, laboratories, and buyers working with magnetic amplifier cores, IEEE 106-1972 helps reduce uncertainty in how test results are obtained and interpreted. That can improve consistency in design validation, procurement, and quality control, especially when different core materials or production lots are involved. Clear test procedures also help limit disputes over performance claims and make it easier to document compliance with established engineering practice for toroidal magnetic components.
