I assume that the system is a spread spectrum device. The frequency band is licence exempt in the US (not Canada - the 2.4GHz band can only be aproved on a case by case basis. Test spec is RSS 210 and/or RSS139(draft)). The test lab must be listed with the FCC (for US) and Industry Canda (for Canada). The spec for the US is 15.247 (intentional stuff), 15.207 (conducted emissions) and 15.209 (unintentional radiated emissions). You will also have to test the digital device per FCC Part 15 subpart B. Test results have to be submitted to the FCC for certification of the transceiver, the digital device may be certified or verified depending on Class/use. >I did some research to find out the applicable approbation's for Europe and >USA. >Europe: >EMC: Emission EN55022 Class B, Immunity Generic standard EN50082-1 ??? or >ETS 300 683 EMC standard for Short Range Devices operating on freq. between 9 >kHz and 25GHz or ETS 300 826 EMC for 2.4GHZ wideband transmission systems >and... or ETS 300 328 Technical product standard (however this standard is >NOT published in the official journal yet ??? For Europe, as it is a radio-communications device, you require Type approval and Type examination. Type approval tests (ETS 300 328) are to do with the way in which the device intentionally uses the radio spectrum. Type Examination tests (prETS 300 826) are more closely aligned with the EMC immunity tests. The results of both have to be submitted to a Notified Body - I strongly advise you contact a local lab capable of interfacing between you and the Notified body so that the test plan is approved prior to testing. > >Safety: ITE standard EN60950. Post: This approbation is unclear for me. Is >the ISM freq. really free, so are NO POST approvals needed in Europe and >USA ?? As I mentioned, the ISM band is licence-exempt. Provided that the device has been certified by the FCC against the relevant parts of FCC Part 15 Subpart C, the device can be used without the user obtaining a licence. In Europe, if the band is licence exempt, the same applies. Regards, Mark Mark Briggs [email protected] --------- This message is coming from the emc-pstc discussion list.
