IEEE 112-2004

IEEE 112-2004 is a technical standard for testing polyphase induction motors and generators, providing a structured procedure for evaluating performance and related electrical characteristics. In the context of power, energy, and industrial applications, it helps engineers and purchasers compare machine results more consistently and supports more reliable technical decisions. Because the document focuses on test procedure rather than product design, it is especially useful where repeatable measurement and clear reporting matter.

IEEE 112-2004 overview

This standard sets out a test procedure for polyphase induction motors and generators, with attention to how results are obtained and interpreted in engineering practice. IEEE 112-2004 is commonly used when a consistent method is needed for measuring operating behavior, losses, efficiency-related values, and other key characteristics of rotating electrical machines. Its role is to support comparable results across testing environments so that equipment can be assessed using a recognized technical framework.

Typical use cases

IEEE 112-2004 is typically relevant during factory testing, acceptance checks, and engineering validation of polyphase induction motors and generators. It may be used by manufacturers, test laboratories, and industrial buyers working with motors for pumps, fans, compressors, conveyors, and similar driven equipment. The standard is also useful in procurement and specification work where measured performance data must be reviewed against a defined procedure before equipment is selected or put into service.

Why this standard matters

Using IEEE 112-2004 helps reduce ambiguity in how machine tests are performed and reported. That matters when performance data influences design approval, efficiency comparisons, warranty discussions, or compliance records. A common test procedure also supports better risk control by making results more repeatable and easier to audit. For organizations handling polyphase induction machines, the standard provides a practical basis for consistent evaluation rather than informal or internally varied methods.
