I read in !emc-pstc that Massimo Polignano <massimo.polign...@esaote.com> wrote (in <OFB42F2B94.C5CABD33-ONC1256AF4 ..00369...@esaote.com>) about 'Keep off the grass: RF emissions!', on Mon, 29 Oct 2001: >Is there any applicable product standard dealing with EMC and safety of >that kind of devices?
In Europe, the Generic EMC Standards would apply plus whatever ETSI standards cover the radio part. For safety, I suppose EN60335-1 if the propulsion is electric. >Do you think it is to be handled as an intentional RF transmitter, >similarly to an ISM? Yes. Unless it's actually an induction system rather than an EM-wave system, in which case the answer gets less definite. What frequency does the transmitter use? >Let's consider it is not an intentional transmitter, as the emission >depends on the broadness of the reference loop, does it make sense to do >measurement at three or ten meters? You probably need to measure the magnetic field if the transmitter has a loop antenna, not the electric field, so the 3m/10m distance requirement is not relevant. But there probably needs to be a specified distance, maybe 1 m. >Do you think immunity as well can be anlysed regardless the actual >installation? Immunity is VERY important. We don't want these things running amok every time an EM disturbance occurs! -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Eat mink and be dreary! ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
