[PSES] ISM-use of a non-ISM frequency
Dear list members, Product in question is an ISM equipment. Classified according to EN 55011:2009/CISPR 11:2009 as class A, group 1 equipment. Using RF energy for a kind of skin treatment, with a probe at the end of a 1-1,5 m long cable. The EN 55011:2009/CISPR 11:2009 has increased radiation limits at the ISM frequencies, which are listed in table 1, but the product is using a frequency that is not in the table. Product is at stand by when the user is not pressing a button, emission being well under the limits. When the button is pressed, the frequency in use is about 5-15 dB above the limits (radiated/conducted). Also when all realistic means for reducing the emission have been introduced (including a good shielding of the cable, and reducing the power as much as possible). The button is pressed some seconds in periods. Using another frequency for the RF is unfortunately not possible. I think that asking a notified body and/or for a special permission/acceptance is a last chance for being able to CE-mark the product. Do you see others possibilities? Any experiance with such a permission, if at all possible?

That is correct. The FCC does not regulate immunity of equipment.

Re: [PSES] FCC and immunity
Very broadly, the USA FCC regulates (both intentional and unintentionable) emitters and not receivers when it promotes that efficient use concept. That's the way that the underlying Communications Act is applied. OTOH, they sometimes do get into control of receivers when they specify technical content like blocked frequency bands, minimum signal-to-noise ratios and tuning requirements. If that type of regulation on receivers was acceptable, then I don't see any barrier to the FCC someday deciding to impose immunity regulations on communication receivers. However, it would be a philosophical reach to try to apply immunity to all electronic devices in general.

Re: [PSES] SELV rated power supplies
Hi Dave: EN60950-1 is not equal to SELV. Certifications and reports do not necessarily indicate outputs are SELV, although careful reading of the test results can conclude that the outputs are SELV or not. Not all outputs of EN60950-1 power supplies are SELV and need not be. The power supplies are nevertheless EN60950-1 power supplies. The requirement for SELV is whether or not the circuit is accessible. Accessible circuits must be SELV. To perform a single-fault test, one must understand how the circuits operate, and what faults could cause the output to possibly exceed SELV limits. In today's power supply topology, such circuit analysis is not necessarily straight-forward. Your statement Therefore my contention is it cannot be assumed that a power supply listed as EN 60950-1 compliant on a manufacturer's data sheet is also SELV compliant unless explicitly stated so or proven in the test report results. is correct.
