Hello Folks,

Just got an estimate for the immunity part of the compliance tests at an
EMC lab: 21 hours. Ouch! I've never had it that long. Is this normal
these days? What's your recent experience? The data:

DUT: Medical equipment, not life-support but cardio-diagnostic stuff.
Pre-compliance looked great and I am sure we'll ace usual the radiated
and conducted emissions tests.

Included tests would be: AC current harmonics, AC flicker, ESD, radiated
immunity, conducted immunity, magnetic immunity, fast transitions, mains
port surge, voltage dips and interrupts.

I've never had this stuff take more than a day. That's why I am asking
for other opinions.

That sounds a bit long. Perhaps they have limited space so they need
to reconfigure their lab before doing a different test. A quote from
another lab wouldn't hurt.


It's a big round-the-clock lab and all the stations are permanently set
up. Our system is light, can be hand-carried to the next station by one
strong guy. Any hint what it would have taken in good ol' Europe? My
last time there is almost 20 years ago and susceptibility took less than
a day.

Over here the price is usually 'fixed'. EMC compliance starts at 8000
euro.
