Do not confuse susceptibility of interference with immunity such as ESD, Fast Transient, etc. The susceptibility spoken of is that of Spectrum Protection, and the protection of licensed users, not ESD, RF immunity, etc. And, the actual law states "....(2) establishing minimum performance standards for home electronic equipment and systems to reduce their susceptibility to interference from radio frequency energy." But then that is the 1982 version. The Telecommunications Act of 1934 amended 1996 is the current law in force, not the 1982. Also, while irrelevant, the 1982 law only changed a few phrases to better describe specific instances. Such as adding "or home electronic equipment and systems" after "devices", and adding who can train and who can give amateur license testing. The relevant law (i.e. Telecommunications Act of 1934 as amended in 1996) says " The Commission may, consistent with the public interest, convenience, and necessity, make reasonable regulations (1) governing the interference potential of devices which in their operation are capable of emitting radio frequency energy by radiation, conduction, or other means in sufficient degree to cause harmful interference to radio communications; and (2) establishing minimum performance standards for home electronic equipment and systems to reduce their susceptibility to interference from radio frequency energy. Such regulations shall be applicable to the manufacture, import, sale, offer for sale, or shipment of such devices and home electronic equipment and systems, and to the use of such devices. Again, this is not immunity in the sense of radiated immunity, ESD, Fast Transient etc., but susceptibility only in regards to protection of the spectrum.

The FCC already has the authority it needs to require *some* RF immunity, and has since 1982: http://www.arrl.org/public-law-97-259 excerpt: The FCC has opted for voluntary standards, rather than formal rules and regulations. The FCC and the ARRL are both active in an industry group (in cooperation with the American National Standards Institute, ANSI) that is studying "RF immunity issues." The Accredited Standards Committee C-63, has set an RFI-rejection standard for certain home electronic equipment. The voluntary standard provides for immunity of consumer equipment to some levels of RF field strength. This standard is not sufficient for full-power amateur stations under "worst case" conditions, but it covers the majority of cases. Starting in the second half of the 1990s, consumers started to see some built-in immunity in consumer products. The industry has a ways to go, but there is some light at the end of the tunnel.
