Medical Device Insulated Wire Flammability Classifications FV-1, VW-1 and FT-1 (CSA)

[phase90]

Per the 3rd edition (601-1), insulated wire in a device needs to be equivalent FV-1 or better. In the data sheets of the wire I am using, it lists the rating as VW-1 and FT-1 (CSA). How do the two (three?) ratings compare?

Thank you for the information. They are not the same.
It does look like FT-1/VW-1 is more severe than 94V (5 applications of 15 second flame vs. 2 applications of 10 second flame).
