What are you changing about the Y-caps? If it's just a new supplier and
the caps conform to the required component standard, there is no
degradation. Reducing he capacitance would be a degradation for EMC but
not for safety.
Who determines the class is the person who has all the necessary data.
The test house of surveillance authority check the decision.

Hello EMC experts,
A question came up today about filing new results to FCC for our
legacy product.
1. If the filing is only for FCC, then the lab providing the report
does not need A2LA accreditation,
2. If the filing is for a safety report, then the lab does need A2LA
accreditation.
Have I got that right?
We're filing some small board changes, including Y-caps and can't
figure out if this is a Class 2 permissible change, defined as:
" includes those modifications which degrade the performance
characteristics as reported to the Commission"
3. How or who determines if our change is Class 2 (degraded
performance) or Class 1?
We think the results are better, but it's not like we got uniformly
more margin across the board.
Thanks!
