Re: Impact using two different materials for product enclosure in radiation and immun
This is an engineering issue, not a regulatory one.
Some thoughts, not necessarily everything you need:
Can you be sure that the two enclosure-segments are conductively bonded at a sufficiently close spacing that there is no potential difference across the joint across the full range of relevant emissions frequencies?
Can you be sure that there won't be a gap between the enclosure-segments of greater width than say a quarter-wavelength of the highest frequency of interest?
Will there be conductive contact between bare metals and a DC potential across the joint, either directly or due to RF rectification, such that electrolytic corrosion might occur?
