Robert, You might try Compliance Engineering magazine. They have a lot of reference material on regulatory compliance for Medical, EMI / RFI, safety, etc. I use them for info on FCC and CE marking, but they also track medical devices compliance issues, especially the new European harmonized requirements. http://www.ce-mag.com Look for the Annual reference Guide, that should get you started.
