Safety isolation voltage vs working isolation voltage rating

We usually only mention safety isolation voltage. in some case, users concern the working isolation voltage. Can we derive the working voltage rating according to the product safety isolation voltage? Here it is for a reference. Does it make sense?

Typical break down voltage rating according to IEC 950

Isolation test voltage(rms)        Rated working voltage (rms)

1000                                        130

1500                                        230

3000                                        1100

6000                                        3050

    Discharging event is a probability event for a gap! More probability margin is needed!
