Specifically, take a look at FCC part 15 rules. It varies by country too (Fcc- USA, VCCI - Japan, CE - European Declaration of Conformity, etc, etc etc). Take a look on the back of your computer, handheld device, etc. The regulatory aspects of making a product are larger than you may think. Radiated Emissions (30MHz and up), from an electronic device are required, along with Conducted Emissions (150kHz - 30MHz - usually for AC powered products)in the US. More for other countried such as Europe. You usually need to test up to the fifth harmonic of the largest clock freq in the device. I believe there's an exception for non-production stuff where you can build 5 units before actually needing compliance. Battery operated may be different too. The point is that you need to be concerned when it goes into production. Try the Linx application note: http://www.linxtechnologies.com/ldocs/pdfs/AN00140.pdf Also, search for "EMC" - electromagnetic compatibility on the net, or EMC test houses. Usually costs ~$3000 to qualify a product.
