Hello Eric and group, I've got the scope in front of me:
DOP 1-march-97 DOW 1-sept-1999 This standard for EMC immunity requirements applies to professional audio, video, audio-visual and entertainment lighting control apparatus as defined in clause 4 intended for use in the environments described in clause 5. ..... Clause 4 definitions professional apparatus : Apparatus to be used in trades, professions or industries and which is not intended for sale to the general public. Clause 5 Electromagnetic environment Environments E1 residential as defined in IEC 1000-2-5 class 1 and 2 E2 Commercial and light industrial f.a. theatres E3 Urban outdoors IEC 1000-2-5 class 6 E4 Controlled emc enviroment broadcasting studios or rural outdoor E5 heavy industrial As in EN 50082-1 and close to transmitters. I suppose , as barcode readers clearly fall into Class E2 or E5 , that this standard applies. You may however define your barcode reader card as NON-VIDEO , but industrial vision application. The definition video is not further explained , but to me this is related to processes were a video signal becomes available for further processing, recording etc. Video signal in the sense of composite video, or any other common video transfer standard. Security systems are also excluded. The normative appendix D speaks about: test procedure ... The output signal of audio apparatus is listened to, of video apparatus is DISPLAYED and VIEWED..... It's your choice now .......... Good luck and regards, Ing.

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.
