According to their titles, these product family standards, which take effect 9-1999, apply to emissions (-1) and immunity (-2) of "audio, video, audiovisual and entertainment lighting control apparatus for professional use".
It is unclear to me what the word "professional" means in the context of these standards. Obviously, the standards to not apply to equipment for home use. I can understand that they may apply to equipment used by professional photographers, video operators, sound mixers, lighting technicians in theaters and entertainment groups such as rock bands. But, do they apply to equipment operated by "normal employees" in a retail, office or light industrial environment? Application examples would include CCTV, audio paging, and intercom equipment. Note that CCTV equipment for security applications is covered by EN 50130-4:1995. Can someone expand on what "professional" covers?
