[PSES] Harmonics test requirement for Japan

Hi, Is there a requirement to test harmonics in Japan to obtain VCCI on an ITE equipment. There is a JIS C 61000-3-2 standard, but it is required by VCCI? If yes, I assume it is been tested to Japanese voltage. Sincerely, [img] Dieter Paasche Senior Product Developer Electrical / EMC Complia

Hi, I have seen that too at HP in Sacramento, CA. One antenna was in Vertical polarization and the other in Vertical. In my personal opinion, it is Ok for pre-scan, but I think it is complicated for the final scan. I think you still have to test each frequency and polarization one by one. Sinc

Re: [PSES] Notice about LVD compliance in a DoC for machinery?

I think that the EMC directive is not specifically mentioned in the MD as it is in RED, unless you consider it a radiation (annex 1 section "1.5.10. Radiation"). However EMC compliance is required in the electrical safety standard for machinery EN60204-1. Sincerely,      Dieter Paasche Se
