Re: [PSES] Necessary Lab accreditations, class 2 permissible change

[John Woodgate]

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!

[PSES] Necessary Lab accreditations, class 2 permissible change

[Brian Gregory]

  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! Colorado
