Hi Michael and the group,

With the exception tissue heating generated by some sources at very high 
frequencies, I wonder if the EM field exposure worries today are a bit 
overblown. I started my experiments in high voltage  (100,000+ Volts, and 
NOT static electricity) around age 13 and by age 14 was regularly immersing 
myself in 10,000+V/m, 300 kHz fields. It was fun, heating up screw driver 
blades from induction heating, lighting incandescent light bulbs (as well as 
fluorescent tubes) without wires, and more. About 600 Watts of RF energy was 
concentrated in the relatively small space I was in and I was uninjured! My 
kids all have two arms, two legs, and one head and I am still here almost 60 
years later and healthier than 90% of adults of any age from 18 on. Some of my 
friends say this explains a lot about me (frying brain cells) though.

I realize this is only one case, but have had a lot of high energy RF exposure 
throughout my life. Such as the field in my dorm room from my amateur radio 
transmitter being so strong that the fluorescent tubes in the room lit up with 
no power and blinked with Morse code. I had to remove the tubes from their 
fixtures and cover with towels so my roommate could sleep.

Still here,
Doug

It’s not quite an “unintentional radiator” but if you had a wireless charger 
which did not contain any communication (e.g., a dumb charging signal without 
handshaking),  then it would come within the scope of the EMCD and the LVD 
(not the RED), and RF Exposure would therefore be an issue under the LVD.

Be surprised if any LVD could cause EMF large enough to pose a danger to Human 
Health. Intentional transmitters maybe, a rare beast to 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?
