>From my initial reading on this topic, it seemed that these standards were
intended for studio-broadcast video/audio applications.  But a recent
thread seems to suggest, to me, that it also applicable to industrial
video.  We have two video acquisition boards that are intended for
"computer vision" applications (e.g. reading barcode, sorting...).  Does
55103 apply in it's scope?  If so, when is/was compliance mandatory?  (In
an old posting it was claimed that March 1997 was the mandatory date, but
that seems to leave no transition period.)  A transcription of the scope of
EN 55103 would be helpful.

The basic specifications (both '103-1 and '103-2) put equipment into
5 environment categories according to their use (E1 thru E5)
E1 residential
E2 Commercial and light industrial
E3 Urban outdoors
E4 Controlled emc enviroment
E5 heavy industrial
The emissions spec '103-1 basically calls up compliance (if its
applicable to the useage) to 10 phenomena
radiated e field emissions 55022 or (55013 if its applicable)
Radiated h field emissions  2 limits
conducted harmonics and flicker 61000-3-2/3
Conducted emissions 55022 55014 continuous and discontinuous (clicks)
inrush current of ac supply
antenna terminals of broadcast receivers 55013
conducted emissions signal and control lines 55022
Immunity 103-2 has the same equipment limits but calls up different
stress levels depending on the used environment (basically uses the
61000 class of immunity tests)
radiated immunity 80-1000MHz 3/10v/m 80%am 61000-4-3
esd 4/8kv 61000-4-2
magnetic immunity
fast transients signal and control ports 61000-4-4
audio interference signal and control ports
fast transients i/p and o/p dc ports and ac ports and functional
earth port
conducted immunity i/p o/p dc ports and ac ports and functional earth
ports 3/10v rms 80% am
ac voltage dips / interruptions / surges (common and differential
mode)
criteria's of pass/fail are detailed in '103-2
this is only a very brief resume i will be using the spec from here
on in and this is only my interpretation of it. if you need to know
more email me direct
