I'll guess it's this way: If your equipment requires a computer system to
work, and you sell that system, then you're responsible for compliance of
what you sell, even if you didn't make it. But I haven't seen power supply
emissions tested with everything plugged into one outlet. Seems to me,
separately powered devices must be separately tested for harmonics and
conducted emissions. Might as well test a whole office of networked
computers -- plugged into one outlet -- for harmonics.

One of our products is sold as a system with several other non-connected
products as well as a computer system and printer. We brought this product
to a well known EMC Testing facility to perform Harmonics testing. They
required that we plugged our product, as well as all of the peripheral
devices, into a power strip and they then tested the complete system
together for Harmonics. Obviously, it failed.
Has anyone else had an EMC Lab make this request of testing the complete
system? Is anyone aware of any document that requires system testing for
Harmonics?
All responses are appreciated.
