Fascinating thought processes here. Who will protect the consumer? And from whom?
It is one thing to impose EMI requirements on equipment to be installed in close proximity on platforms. There as pointed out the close proximity of susceptible equipment to high power sources, and not mentioned but also key, the juxtaposition of sensitive receivers to unintentional rf sources, makes the imposition of equipment-level requirements economical alternatives to checking compatibility solely at the point of integration. But this idea that the poor defenseless consumer must be protected against the uncaring free market by the beneficent state – where does that come from? It may well be as Mr. Woodgate states in Europe, that with high population densities and a dense electromagnetic environment that enough problems surfaced to make it again an economical solution to introduce an artificially leveled playing field via government mandate. But in the absence of that situation, which is clearly where we are at in the USA, it is either comical or tragical that someone feels that the government must step in to provide protection not afforded by the invisible hand of the free market. If I buy a laptop that freezes or loses its memory when I open it up at an airport, I make a mental note not to buy a product from that company again. Now in cases where the free market doesn’t work, you may need some extra help. If I don’t wake up from a medical operation because the equipment used during that operation malfunctioned, then there will be a free market correction, but it is too late to help me out. So there the FDA steps in. But the idea of government stepping in where it isn’t absolutely mandatory can’t help but dredge up memories of all the absolutely ridiculous pronouncements that continuously emanate from on high. For those of you who live in California, or who have ever traveled there, just how many health hazards are “known to the State of California” ? And what is the rate-of-increase of such postings? One would come to the conclusion that either the state of California is much smarter than the rest of the forty-nine states, or that CA is a very unhealthy place to live.

In the railway industry at least it gives us some idea if a piece of equipment is going to last more than 5 minutes. Without the standards everything would have to be subject to extensive and expensive testing on the trains. I think the consumer would notice the removal of the standards with increased equipment failures and reliability issues with equipment in the home - who wants their washing machine skipping the spin cycle because someone stood too close with a mobile phone. In truth it may not be the FCC concern as such but if not them who will protect the consumer?
