RM6 based offline flyback cannot pass mains isolation test?

[Faringdon]

Hi,
Do you agree, an RM6 based offline flyback for 115VAC cannot pass isolation testing of "2500VAC for one minute"?
The secondary windings, when terminated to those pins, is too close... , ..basically, since the pins themselves are too close to the primary windings on the RM6 bobbin?

Do you know of any list of standard ferrite bobbins which cannot pass  "2500VAC for one minute"?

AFAIK the pins don't reach through to the winding side. So it should be possible to keep enough distance. Worst case consider potting with good dielectric strenght as a last resort - chances are you could get to the 20 kV range this way.

We designd and shipped 7000  PSU in 1980s, based on RM6, RM8

advise...avoid RM6 at all cost!

delicate, not rated for line safety, pins break

Use modern shape with split bobbin
