As engineers, we should consider the safety implications of what we design, test or otherwise work on. EMI is part of that. What is considered a safety risk depends a great deal on corporate policy, the legal, political and popular climate in one's state of residence, and the kind of equipment under consideration.
As it happens, the issue of pacemaker vulnerability is addressed in more regulations than USC 47. That is why, in the United States, we have not only a limit on microwave oven leakage, but also pacemaker warning signs on microwave ovens used by the public. The robotic arm is a great example. Others are automotive airbags, or electronically controlled brakes. These sort of things are the reason why industry associations develop limits of their own. Those limits accommodate both a performance requirement and practical aspects; they can't make the product too expensive to build or no one will be able to sell them at a profit. They can't be unreliable in the field or people won't buy them at all. And they can't cause too many problems, or the company will be sued. One factor weighs against another. We are at the balance point. Regards, Cortland Richmond (What I write here is mine alone. My employer does not Concur, agree or else endorse These words, their tone, or thought.)
