Fire Testing - EN 50339 Not 20 minutes

Hi fellas,

I don't know if I'm in the right section now but we're generally working under 17025 as a laboratory.

I'm mainly doing fire tests today on cable but I can't seem to find a solid answer in the standard EN 50399.
We have a limit of heat at 250 degrees Celsius to not damage our equipment.

In this example I reached the 250+ degrees and had to manually extinguish the fire, BUT according to my data from our software the cable is still in Class D, which is approved.

My question is; When I can't run the test for the full period of 20 minutes, are my data valid as a result OR is it just failed?

Thanks in advance.
