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.

These web pages are freely offered to anyone who wishes to use them. No warranty for their use is expressed or implied. The most-current versions may be downloaded from the our web site at http://www.dbicorporation.com/.

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.

Robust Electronic Design, Inc. is the research arm of dBi Corporation, an A2LA-accredited EMC/EMI/ESD testing and consulting company based in Lexington, Kentucky. Our staff has been directly involved in putting over 115 major electronic products into mass production at Sycor, IBM, and Lexmark, as well as doing the EMC/ EMI/ ESD engineering tests and FCC/ CE-Marking approval tests for over 231 products and 3 testers developed by clients-- bringing them into compliance with both domestic and international laws and standards. Our staff has also served as an expert witness on electronics in three lawsuits. We have over 36 years experience in the computer and electronics industries developing electronic products and electronic equipment that:
  1. Work.
  2. Are safe and reliable.
  3. Can be manufactured, tested, repaired, and serviced economically.
  4. May be sold and used worldwide.
  5. Can be easily adapted/enhanced to meet new and changing requirements.

Our President, John R. Barnes, is a Professional Engineer (PE) licensed in the state of Kentucky, a NARTE-Certified Electromagnetic Compatibility Engineer (NCE), a NARTE-Certified Electromagnetic Compatibility Technician (NCT), a NARTE-Certified Electrostatic Discharge Control Engineer (ESDC Eng), a NARTE-Certified Electrostatic Discharge Control Technician (ESDC Tech), a NARTE-Certified Product Safety Engineer (PSE), a Senior Member of the IEEE (SM IEEE), and an Advanced-class amateur radio operator. He has written three books: Electronic System Design: Interference and Noise Control Techniques, which was published in English in 1987 and in Russian in 1990; and Robust Electronic Design Reference Book, Volumes I and II, which came out in 2004. John has also written articles on designing electronics for electrostatic discharge (ESD) immunity for Printed Circuit Design and Conformity magazines.
