Magnetic Field Immunity Standards for Commercial Electronic Products

This web site is being maintained by John R. Barnes, who was the President and Chief Engineer of dBi Corporation from 2002 to September 30, 2013, when we closed because ObamaCrap made it too expensive for us to remain in business.

Magnetic Field Immunity tests check the behavior of products when exposed to powerline- frequency magnetic fields, such as from poorly- routed power wiring. Because these fields are continuous, and out of the user's control, immunity standards require the product to meet Performance Criterion A. I.e., it must operate normally, without any user intervention.

The table below summarizes the evolution of Magnetic Field Immunity standards for commercial electronic products. Medical electronics and military electronics may have their own special requirements. The links take you to summaries of the standards and their amendments. "(Modified)" means that the standard/ amendment differs from the reference standard/ amendment. Entries in bold text are currently active for undated references. Please note that in Australia and New Zealand, products only need to comply with safety and emission standards to bear the C-Tick mark.

These web pages can point you to regulations and standards applying to your product(s), but please refer to the regulations and standards themselves when deciding how to test your product(s). A regulation's or standard's title gives you strong clues as to what it covers, but its scope (usually section 1) tells you for sure. Carefully check the footnotes in tables, to see if your product falls into an exception that lets you avoid unnecessary tests (or sometimes requires additional special testing). Exceptions that can help you also sometimes hide in the Test Setup section (usually section 7). Also check the Test Report section (usually section 10) for any special documentation required.

dBi Corporation was a one-man test house (testing laboratory) based in Lexington, Kentucky, testing a wide variety of commercial electronic products for electromagnetic compatibility (EMC), electromagnetic interference (EMI), and electrostatic discharge (ESD) under its ISO 17025 accreditation. dBi was founded in Winchester, Kentucky in 1995 by Donald R. Bush, shortly after he retired from 30 years service with IBM Lexington's/ Lexmark's EMC Lab. John R. Barnes, who'd worked with Don at IBM Lexington and Lexmark, bought dBi in 2002 after Don's death, and moved the company to Lexington, Kentucky. John closed dBi at 11:59pm EDT on September 30, 2013, because ObamaCrap had increased operating expenses to the point that we could no longer afford to remain in business.

We'd like to thank all of the clients who chose dBi to test their products from 1995 to 2013. Below is a brief summary of our accomplishments during the 18 years we were in business.

From 1995 to 2001, under Don Bush's ownership and operation, dBi:
