http://www.amazon.com/exec/obidos/ASIN/188493210X/rfidhandbook-20 I got this book and have read it, more math than I want to work thru. It points out a lot of the pitfalls of measuring low freq EMF. Basically if you want only 50/60 Hz, get a meter tuned for that only. Otherwise a broader band meter will pick up higher frequencies more effectivily and they will be the high reading with no indication to you that it's from a freq. you are not interested in.
"Kunde, Brian" <[email protected]> wrote: My fellow colleagues, We would like to come up with an internal test to ball-park measure electromagnetic fields at line frequency (50/60Hz) to satisfy our customers when such requests are made regarding compliance to the EU's Physical Agents Directive (2004/40/EC). Any advice regarding test setup and test equipment would be appreciated. Our EMC/Safety lab does not have much expertise in EMF test methods and equipment. We assume that our products would have no problem meeting the directive's requirements, but when customers ask, we would like to give them something. Instead of spending a lot of time and money testing products at qualified labs, we are looking for a simple test setup and test equipment to perform some kind of test ourselves. 1. For IT and Laboratory equipment, what EMF test method standard should we be looking at? Is there a harmonized test standard? 2. What test equipment is required? A Google search popped up a lot of hand held products that claim to measure EMF. Would such products do what we need? 3. Is this approach doable, or have I embarrassed myself by even proposing such a test? Thanks to all in advance.
