Re: [PSES] EN62311 - Human Exposure to Electromagnetic Fields

[John Woodgate]

The frequency range is DC to 300 GHz, so power frequency magnetic fields 
are included. Some household appliances used to produce quite strong 
fields very close to the casing. Historically, bulk erasers for magnetic 
recording tape produced strong magnetic fields. The requirements include 
large 'safety factors' because research is ethically challenging, and 
adverse health effects are widely attributed to causes other than the 
real ones.

Be surprised if any LVD could cause EMF large enough to pose a danger

create those levels unintentionally at less than 1000V.

It applies to any LVD product, but there is a flow chart that shows 
that a simple assessment is possible if the product has no reasonable 
likelihood of producing sufficiently strong EMF.

    EN62311 is listed in OJ and a harmonized LVD standard.

    Does EN62311apply to any LVD product or only products containing
    radio transmitters?
