IEEE P2665/D2, May 2022

IEEE P2665/D2, May 2022 is a draft recommended practice for statistical process control in EMC test laboratories. It addresses how laboratory data can be monitored and interpreted so that electromagnetic compatibility testing remains consistent, traceable, and better controlled over time. In the context of fields, waves, and electromagnetics, this document is relevant to teams that need to manage test variation and support dependable EMC results during development, qualification, and ongoing laboratory operations.

About IEEE P2665/D2, May 2022

IEEE P2665/D2, May 2022 focuses on applying statistical process control methods to EMC test laboratory work. Its purpose is to help laboratories observe process behavior, detect unusual variation, and maintain more stable test conditions. As a draft recommended practice, it is intended to guide technical decision-making rather than define a product specification. The standard is most relevant where repeatability, measurement discipline, and process awareness are important to electromagnetic compatibility testing and laboratory quality control.

Where is IEEE P2665/D2, May 2022 used?

This document is typically used in EMC test laboratories that perform emissions or immunity testing on electronic equipment, subsystems, and related components. It may also support engineering organizations that rely on outside labs and need confidence in test consistency. Workflows involving routine measurements, chamber-based testing, instrumentation checks, and trend review can benefit from the statistical methods described in IEEE P2665/D2, May 2022. It is especially useful where small shifts in setup or equipment behavior can affect reported EMC results.

Importance in practice

In practice, IEEE P2665/D2, May 2022 helps reduce uncertainty in EMC testing by encouraging disciplined monitoring of laboratory processes. That can support better repeatability, clearer identification of drift, and more reliable comparisons between test runs. For compliance work, controlled processes can lower the risk of inconsistent results that delay product approval or trigger retesting. It also helps laboratories document performance trends and strengthen confidence in measurements used for design decisions, procurement review, and technical reporting.
