Thanks John, I was the one who mentioned OATS under an assumption that if doing very close distant compliance measurements then far field measurements might also need consideration for EMC emissions.
The first question for any company producing an electrical product should be, “what regulatory compliance is in place for our product type in countries X, Y, Z ? ” That should be the starting point and then the details follow from there and then, eventually, a presentation discussion to a “CEO” or senior executive management about how much it will cost to offer a complain device in the market space of greatest opportunity. Then finance and market need to determine ROI and opportunity cost. It should be a harmonious and balanced effort between marketing, engineering, and finance depts.

The ICNIRP documents are scientific reports recommending limits of exposure to electromagnetic field is the context of human health. I may have been misled by Brian Kunde's use of 'EMF', so directed him to the IEC standards based on the ICNIRP recommendations. If the context is electromagnetic compatibility, and it is emissions that are to be measured, not immunity, the standards produced by IEC SC77A might be more applicable, but treatment of 'very close distances' is rare. Some responders have not noticed the words 'very close distances', and have discussed open-air test sites. <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient> Virus-free. <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient> www.avg.com _____ This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
