Hi Amund,
I read your email (below). I'm no medical device expert; but I'm
wondering if the magnetic strength limit was set so high due to MRI
(Magnetic Resnonance Imaging) devices. My understanding is that MRI
devices produce HUGE magnetic field levels. According to a recent
newspaper story
Hi,
I can help much, but, for this paragraph, the rationale at the back of the
standard states that Annex AAA of the Collateral Standard IEC 60601-1-2
states that the limits and methodology are under consideration by technical
