• FCC 47 CFR is published in the Code of Federal Regulations in the early spring of each year- but only includes revisions up to October 1 of the previous year. So this published (and downloadable) version will be 6 to 18 months out of date.
• The FCC publishes a new or revised regulation as a "Report and Order" in the Federal Register. This Report and Order specifies the Effective Date for the regulation.
• The FCC may also publish a "Public Notice" in the Federal Register which reaffirms the effective date for the regulation.
• EMC/EMI/ESD records must be kept for 2 years "after the manufacture of said equipment has been permanently discontinued", or until the "conclusion of an investigation or proceeding ... involving the equipment".

These web pages can point you to regulations and standards applying to your product(s), but please refer to the regulations and standards themselves when deciding how to test your product(s). A regulation's or standard's title gives you strong clues as to what it covers, but its scope (usually section 1) tells you for sure. Carefully check the footnotes in tables, to see if your product falls into an exception that lets you avoid unnecessary tests (or sometimes requires additional special testing). Exceptions that can help you also sometimes hide in the Test Setup section (usually section 7). Also check the Test Report section (usually section 10) for any special documentation required.
