RE: Clocks and calculators Dear all , (I think I am opening a can of worms ... ) The earlier thread get me thinking about those items that are excluded (from FCC testing and now DOC) even if it "...generated and uses timing pulses at a rate in excess of 9000 pulses per second and uses digital techniques....". Can some of you reconfirm what was long held and believe to be true. The list includes: Wrist Watches, (... if it is small enough to be worn on a wrist....) Pocket Calculators, (or be put into a pocket...) Coffee Makers... (or that it trully makes coffee) AFAIK, these things was "exempted from testing to FCC standards" because they have not known to cause any EMC problem in the past. Please add to this list. I have for years never to seek out the reference and it is now time to hear from you quote the chapter and 'verse' where the FCC state that these are exempted.... sincerely, :-) Tim Foo "Sykes, William Thomas (Tom)" <[email protected]> wrote on 08/05/2004 07:27 AM All: Please refer to the "Guidelines on the application of Directive 89/336/EEC" at http://europa.eu.int/comm/enterprise/electr_equipment/emc/guides/chapfive.ht m . In Section 5.4 "Additional practical criteria (accepted by consensus) to exclude equipment from the scope of the EMC Directive." 5.4.1 "Practical criteria and illustrative examples" it states "Although it should in principle be considered as within the scope of the Directive, the following apparatus can be considered as exempted, based upon both of the following criteria, which have also been taken in account into the development of EMC standards: ...Other equipment fulfilling the criteria above:... Quartz wrist watches without additional functions (e.g. radio receivers)." So it appears that quartz watches are exempt by their own words, but if you have additional functions that involve a clock (oscillator), I would at least do a prescreen to see what kind of emissions were present.
