ISO7742: About UL certification

Part Number: ISO7742

Hello support team,

I have some questions regarding UL certification of ISO7742DW.
I confirmed the status of ISO 7742 by UL certification search.
Just to be sure, I'd like to confirm the following contents.

A question
1. Is the UL certification condition correct as follows?
- UL file No: E181974
- Product category: FPPT 2
- Withstanding isolation voltage: 5700 Vac

2. The withstanding isolation voltage is specified as 5000 Vrms in the data sheet, why?
Isn't it 5700 Vrms?

3. cUL certification (FPPT8) does not seem to be certified. Is it correct?

Best regards,
M. Tachibana
